Dr. Ahmed M. Adawy, Professor Emeritus, Dep. Oral & Maxillofacial Surgery. Former Dean, Faculty of Dental Medicine, Al-Azhar University. Condylar fractures represent one of the most controversial issues in maxillofacial traumatology regarding classification, diagnoses and therapeutic management. Classification systems of condylar fracture is discussed. Diagnosis is usually based on history clinical examination and radiographic finding. Treatment ranges from observation, jaw exercises to closed or opened interventions. For years closed reduction was thought to be essentially complication-free. Several serious complications however have been reported including temporomandibular joint ankyloses, malocclusion, mandibular deviation and the generative joint pathology. The absolute and relative indications for open reduction is given. The debate between supporters of open or closed reduction is still continuing and the issue has not been resolved. However, the final choice treatment modality should takes into account the location of the fracture, age of the patient, presence or absence of other associated injuries, cosmetic impact of the surgery and presence of other systemic medical conditions.

Mandibular angle fractures account for 23% to 42% of all facial fractures. Fracture of mandibular angle can be classified as (A) Vertical favorable or unfavorable, (B) Horizontally favorable of unfavorable. Traditionally, mandibular angle fractures have been treated with either closed reduction and inter-maxillary fixation or open reduction and internal fixation with or without inter-maxillary fixation. Patients treated with inter-maxillary fixation have a restricted airway and loose excess weight. Rigid internal fixation and early return to function have eliminated the use of wire osteosenthysis and prolonged use of inter-maxillary fixation. The principal of rigid fixation, however, have inherent set of disadvantages including damage to the inferior alveolar nerve and the marginal mandibular branch of facial nerve. Postoperative malocclusion rates are also high. With the introduction of semi-rigid technique fracture of the mandibular angle could be treated according to Champy’s Ideal lines of osteosenthysis. The technique involves placement of a single monocortial miniplate on the superior border of the mandible. However, some studies suggested using a second miniplate along the inferior border. Wether one or two miniplates should be used is still debatable. The application of 3D plates may provide additional stability in 3 dimension and good resistance against torque forces.

Mandibular fractures
Dr. Ahmed M. Adawy
Professor Emeritus, Dept. Oral & Maxillofacial Surg.
Former Dean, Faculty of Dental Medicine
Al-Azhar University
Fractures of the mandible are a common form of facial injury in adults and occur most frequently in males during the third decade of life. The main causes of mandibular fractures are road traffic accidents, interpersonal violence, falls and sport injuries. Mandibular fractures are classified according to various criteria. The three main factors to consider are the cause of the fracture, the type of fracture and the site of the fracture. Clinical diagnosis as well as radiographic examinations are presented. Treatment modalities are discussed. Moreover, treatment-related complications are given.
Clinical & surgical management of the mandibular condylar process fractures has generated a great deal of controversy in maxillofacial trauma and there are many various approaches to treat this injury. Before, many surgeons seem to favor closed treatment with maxillomandibular fixation (MMF), but recently open treatment of condylar fractures with rigid internal fixation (RIF) has become more common & acceptable. The objective of this presentation was to evaluate the factors that determine the choice of method for treatment of condylar fractures: open or closed, pointing out their indications, contra-indications, advantages and disadvantages.
Facial trauma is without doubt a most challenging area within the specialty of oral and maxillofacial surgery. Trauma with all its aspects has great importance, being the main cause of morbidity and mortality with rising frequency worldwide, especially in recent decades. Traumatic facial injuries are often associated with high mortality and varying degrees of physical, functional, psychological damage, cosmetic disfigurement, and concomitant injuries to other organs that may be added complicating factors. Road traffic accidents represent the main cause of facial trauma. According to WHO, Egypt leads the Middle East when it comes to road accidents, with an average of 12,000 people killed annually. Interpersonal violence is the second most prevalent etiologic factor. Our society is progressively becoming more and more violent and impatient, perhaps due to overcrowding, so the frequency of patients reporting in emergency with facial bones fracture is increasing.
During the last three decades, significant advances have occurred in the methods of fixation used for facial bone fractures, resulting in improved functional and aesthetic outcomes. Surgical techniques have been moving away from delayed closed reduction with internal wires suspension to early open reduction and internal plate fixation. The transition from wire osteosynthesis to rigid internal fixation in facial bone fractures using different micro or mini-plates and screw systems is regarded as one of the greatest advances in the field of maxillofacial surgery. I hope this book reflects the latest trends, concepts and innovations in the care of patients with facial trauma.
For convenience, the text is divided into 3 sections. Section 1 deals with primary care of the patients. Section 2 is concerned with midface fractures. In section 3 management of trauma to the lower face is discussed. Upper face injuries are not included and the reader could find the subject elsewhere under the topic of craniofacial traumatology. From the basic to the most complex, readers will find that each chapter is sequentially organized to provide a concise, and practical description of the operative details. The goal was to provide the reader with a fully comprehensive, yet highly illustrated text on the subject of facial trauma.
Zygomatic Complex Fractures
Dr. Ahmed M. Adawy
Professor Emeritus, Dept. Oral & Maxillofacial Surg.
Former Dean, Faculty of Dental Medicine
Al-Azhar University
The term “zygomatic complex” refers to zygomatic bone and parts of maxilla, frontal, temporal and sphenoid bone. Fracture of the zygomatic complex, also known as a quadripod fracture, and formerly referred to as a tripod fracture, varies in severity from a simple crack to major disruption. The etiology, clinical presentations, and radiographic findings are presented. Classification systems are mentioned. The management of zygomatic complex fracture depends on the degree of displacement and the resultant esthetical and functional deficit. As a general rule, non- displaced or minimal displaced fracture can usually be treated conservatively. On the other hand, open reduction and internal fixation is applied in all dislocated, instable, and comminuted fractures of the zygomatic bone. Different surgical approaches and fixation methods are discussed.

Maxillofacial trauma is without doubt a most challenging area within the specialty of oral and maxillofacial surgery. As with all traumas, basic Advanced Trauma Life Support principles (ATLS) should be applied to the initial assessment of the casualty. The primary survey is given by the letters ABCDE.
• Airway maintenance with cervical spine protection.
• Breathing and ventilation.
• Circulation with hemorrhage control.
• Disability: neurological status.
• Exposure/environmental control - undress the patient but prevent hypothermia.
Each was explored and discussed.
The primary goal of the present book is to produce a comprehensive text that fully integrates the latest concepts and techniques in management of odontogenic infections. The main aim is to provide the readers with an update information regarding pathophysiology, clinical and radiographic presentation, microbiology, diagnosis, management, and complications of odontogenic infections. Accordingly, the text has been divided into six chapters. Chapter one is concerned with oral microbiology and immunology. Chapter two is dealing with the pathophysiology of odontogenic infections. In chapter three, management of odontogenic infections is presented. In chapter four, antibiotic therapy of odontogenic infections is given. Chapter five deals with life-threatening complications. In chapter six osteomyelitis of the jaws is discussed.
Nasal and nasoethmoidal fractures.
Dr. Ahmed M. Adawy
Professor Emeritus, Dept. Oral & Maxillofacial Surg.
Former Dean, Faculty of Dental Medicine
Al-Azhar University
Nasal bone fractures comprise up to 50% of all facial fractures. Nasal fractures can be classified in two broad categories based on impact force: lateral-type versus frontal-type injuries. Lateral-type injuries tend to be more common, have fewer residual anatomic and functional defects compared with frontal injuries, and are more amenable to closed reduction. Frontal injuries classically produce a posteriorly displaced fracture where the nasal septum is always involved. They have a higher risk of residual post-surgical deformity, and as the impact force increases, nasal, orbital, and ethmoidal fractures occur in combination. The extent of the septal injury determines the appropriate technique for septal correction. Closed reduction of fractured nasal bone can be performed by elevation of depressed bones or depression of elevated bones to restore the symmetry of the nasal aperture. Septal injuries that cannot be realigned with a closed reduction should be addressed with open techniques. Symmetrical fixation of the bones, restoration of orbital volume, globe position, frontonasal angle, and nasal projection are essential for a satisfactory cosmetic outcome.
Management of soft tissue injuries in facial traumaAhmed Adawy

Professor Emeritus, Dept. Oral & Maxillofacial Surg.
Former Dean, Faculty of Dental Medicine, Al-Azhar University.
Soft-tissue injuries are the most common presentation following maxillofacial trauma. In general, injuries can initially be classified as open or closed wounds. A closed wound is one that damages underlying tissue and/or structures without breaking the skin. Examples of closed wounds include hematomas, contusions, and crush injuries. In contrast, open wounds involve a break in the skin, which exposes the underlying structures to the external environment. Open wounds include simple and complex lacerations, avulsions, punctures, abrasions, accidental tattooing, and retained foreign body. Detailed description of management is presented. The principles of repair is discussed.

The term “blow out” refers to partial herniation of the orbital contents through one of its walls. This usually occurs via blunt force trauma to the eye. Most often, the orbital floor is fractured in conjunction with the inferior orbital rim “impure” blowout fracture, but “pure” orbital floor fractures, with intact orbital rim can be seen. An extensive and careful history, physical examination, together with CT scans is vital for the diagnosis of orbital floor fractures. The timing of treatment, surgical approaches, and reconstruction of the orbital floor are presented.
Facial bone fractures: an overview
Dr. Ahmed M. Adawy
Professor Emeritus, Dept. Oral & Maxillofacial Surg.
Former Dean, Faculty of Dental Medicine
Al-Azhar University
The bone and soft tissues of the face are able to absorb the energy from impact forces. Force to the bone in the elastic range causing the deformation and after force removal, bone returns to its previous state, but if the force be greater than the elasticity of bone, a permanent displacement occurs and be irreversible. Furthermore, when these forces exceed the strength of these tissues, a variety of fractures can occur. The buttress theory proposes that the midfacial region is like a framework that is stabilized by horizontal and vertical buttresses. The most common causes of maxillofacial trauma are traffic accidents, injuries from fights, sport accidents or falls. The Le Fort’s classification is based on low-velocity trauma, and does not completely reflect the breadth of high-velocity fractures encountered in modern practice. Currently, facial fractures are classified into central midface fractures, lateral midface fractures and mandibular fractures. Nasal, nasoethmoidal, Zygomatic bone, and orbital fractures are presented. Today, surgical techniques have been moving away from delayed closed reduction with internal wires suspension to early open reduction and internal plate fixation. Different treatment approaches exist to restore the facial skeleton using the different facial buttresses as landmarks.

Salivary glands are exocrine glands that produce saliva through a series of ducts. The glands may be affected by a wide range of disorders. They can be involved with acute and chronic inflammatory processes, give rise to benign and malignant tumors, manifest congenital abnormalities or represent involvement of a systemic disorder. Further, partial or complete obstruction of the ductal element can occurs. Physical examination and diagnostic aids are presented. Current surgical managements of these disorders are discussed.
Oral surgery during pregnancy
Dr. Ahmed M. Adawy
Professor Emeritus, Dep. Oral & Maxillofacial Surg.
Former Dean, Faculty of Dental Medicine
Al-Azhar University
Pregnancy, also known as gestation, is the time during which a fetus develops inside a woman's uterus. Pregnancy is typically divided into three trimesters. The common belief has been that, if an oral surgery procedure is recommended, but it’s not an emergency, the second trimester is the ideal time. Pregnancy however, is not a disease and pregnant woman should not be treated differently than the general population. In short, it could be concluded that:
• Dental care is safe and essential during pregnancy
• Pregnancy is not a reason to defer routine dental care or treatment
• Diagnostic measures, including needed dental x-rays, can be undertaken safely
• Emergency care should be provided at any time during pregnancy
Diabetes mellitus is a group of metabolic diseases characterized by high blood glucose level caused by either absolute or relative deficiency of insulin. Classifications,sings and symptoms,complications,and prevalence of the disease particularly in Egypt are presented. Management of diabetic patients undergoing oral surgical procedures is discussed.
Differential diagnosis of oral and maxillofacial lesionsAhmed Adawy
A wide variety of lesions from the soft and hard tissues may arise in the orofacial region. Clinical diagnosis is a cognitive process of applying logic and knowledge in a series of step-by-step decisions, to create a list of possible diagnosis.

The condition of being prognathic indicates abnormal forward projection of one or of both jaws beyond the established normal relationship with the cranial base. The skeletal manifestation can be due to mandibular anterior positioning (prognathism) or growth excess (macrognathia), maxillary posterior positioning (retrognathism) or growth deficiency (micrognathia), or a combination of both. The prevalence of mandibular prognathism, the etiologic factors, evaluation of patients, and treatment modalities are presented.

1.Autogenous bone grafts in the form of nonvascularized free bone transfer, or vascularized tissue transfer, either pedicled or based on microvascular anastomosis
2. Distraction osteogenesis
3. Alloplastic materials (with or without bone)
4. Tissue engineered grafts

By definition, a cyst is a “pouch” or sac without an opening, provided with a distinct membrane, and containing fluid or semifluid material, abnormally developed in one of the natural cavities or in the substance of an organ. Cysts of the oral region may be epithelial or non-epithelial, odontogenic or non-odontogenic, developmental, or inflammatory in origin. The distribution of jaw cysts according to diagnosis in a general population is given. The treatment of choice is dependent on the size and localization of the lesion, the bone integrity of the cystic wall, its proximity to vital structures and patient age.Treatment modalities are discussed.
Arthrocentesis of the temporomandibular jointAhmed Adawy
Dr. Ahmed M. Adawy, Professor Emeritus, Dep. Oral & Maxillofacial Surgery. Former Dean, Faculty of Dental Medicine, Al-Azhar University. Arthrocentesis of the temporomandibular joint refers to lavage of the upper joint space, hydraulic pressure and manipulation to release adhesions of the “anchored disc phenomenon” and improve motion. The technique of arthrocentesis is discussed together with the indications and contraindications of the procedure. Further, the presentation includes modifications of the standard technique.
Teeth in The Line of Mandibular FracturesAhmed Adawy
Dr. Ahmed M. Adawy, Professor Emeritus, Dep. Oral & Maxillofacial Surgery. Former Dean, Faculty of Dental Medicine, Al-Azhar University. Approximately 60% of fractures of the mandible occur in the teeth bearing area. Incisors and third molars are the most commonly involved teeth on the fracture lines. The damaged to the tooth involved at the fracture site may include exposure of the root surface subluxation, avulsion or root fracture. This may lead to the vitalization, consequent infection and complicated healing of the fraction. Wether to remove or preserve the tooth in line of fraction is discussed. Certain guidelines have been suggested.
Mandibular Radiolucencies; A Systematic Approach to DiagnosisAhmed Adawy
Dr. Ahmed M. Adawy, Professor Emeritus, Dep. Oral & Maxillofacial Surgery. Former Dean, Faculty
of Dental Medicine, Al-Azhar University. Conventional radiography may revel a variety of
radiolucent legions in the mandible. Interpretation of such radiolucencies can be challenging either
because the clinical presentation may be non specific or because the ;legion is detected
incidentally. Further, interpretation may vary from one examiner to another. thus, systemic
approach is necessary to diagnose the legion or at least provide a meaningful deferential
diagnosis. This approach should focus on specific radiographic parameters. Initially, the legion
should be placed in the category of either normal or abnormal. The presented parameters includes
describing the legion in terms of: 1- Location, 2- Margins, 3- Size and shape, 4- Effect on
surrounding structures. Obviously, however diagnosis of a legion should never be made
exclusively on the bases of radiographic interpretation. Radiographic interpretation should be used
along with clinical information and other tests to formulate a deferential diagnosis.
Dr. Ahmed M. Adawy, Professor Emeritus, Dep. Oral & Maxillofacial Surgery. Former Dean, Faculty of Dental Medicine, Al-Azhar University. Ameloblastoma is benign slow-growing but locally invasive neoplasm of odontogenic origin. In 2005, the WHO has classified ameloblastomas into multi cystic, unicystic and peripheral subtypes. The clinical picture, radiographic findings and differential diagnosis are presented. Treatment of ameloblastomas is primarily surgical. There has been some debate regarding the most appropriate method for removing. These range from conservative to radical modes. Some authors advocate conservative approach and thought that ameloblastoma are essentially benign in nature and should be treated as such. However, this conservative approach result in recurrence rates of 55% to 90%of the cases. Currently, the standard of care for ameloblastoma includes en bloc resection with 1-2 combine margin and immediate bone reconstruction. Despite the medical nature of a surgical resection, it may actually involve less morbidity than extensive hard and soft tissue resection with associated extensive morbidity that may be warranted in case of recurrence following inadequate primary treatment.
Dr. Ahmed M. Adawy, Professor Emeritus, Dep. Oral & Maxillofacial Surgery. Former Dean, Faculty of Dental Medicine
Al-Azhar University. Impacted teeth can be defined as those prevented from eruption at the expected time due to physical barrier. The etiology, frequency of impactions are given. Classification systems are based on the depth, angulation, and available space. Complications associated with lower third molar impaction are discussed and methods of treatment are explained. Comparison between maxillary third molar and mandibular one is given. Upper canine is the second most commonly impacted tooth after third molars. It form the foundation of an esthetic smile. The management of impacted canine is interdisciplinary management comprises of a team of an orthodontist, oral surgeon, and periodontist.

Maxillary sinusitis is an inflammation of the sinus. Odontogenic causes represent nearly 30% of the etiology. Clinical and radiographic examinations are discussed together with treatment plan.
Oro-antral fistula is a rare complication of surgery at the posterior maxillary region. Several techniques for closure are presented. Additionally, information about sinus lift procedure is given.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

3. Fractures of mandibular condyle can be counted among
the most controversial issues in maxillofacial
traumatology regarding classification, diagnosis and
therapeutic management.
Despite the fact that the temporomandibular joint is well
protected in the glenoid fossa, and that the condylar
process is relatively well protected by the zygomatic
arch against direct injury, condylar injuries are relatively
common. Condylar fractures represent 29-40% of the
fractures of the facial skeleton, and about 20-35% of all
mandibular fractures
.
(1)
4. In terms of strength, the condylar neck constitutes the
weakest region of the entire mandible and is therefore the
most susceptible to fracture as a result of indirect forces,
where the forces of impact are transmitted along the
mandible from distant sites such as the angle, body or
symphysis to the condylar neck. The central force in the
middle of chin can cause a bilateral condylar fracture. The
most common causative factors are physical trauma,
accident, fall, sports injury, gunshot wounds and industrial
hazard. Unilateral fractures occur approximately 3 times
more frequently than bilateral fractures do, but bilateral
fractures are not uncommon
5. Several classification systems have been developed.
Generally, there are two types of fracture,
intracapsular and extracapsular, but for practical
purposes, the anatomical level of the fracture is
divided into three sites: the condylar head
(intracapsular), the condylar neck (high or low) and
the subcondylar region (2). The fracture is farther
classified as: undisplaced, deviated, displaced (with
medial or lateral overlap, or complete separation),
and dislocated (outside the glenoid fossa) (3)
6.
7. One of the most commonly used classifications was
that developed by Spiessel and Schroll (4). They
distinguish between fractures of the condylar base
and neck, and based on the fracture position and the
relationship between the fracture fragment and
glenoid fossa
8. Type I, condylar
neck fracture,
without deviation/
displacement of
the fragments.
Spiessel and Schroll, 1972
9. Type II, low condylar
neck fracture with
deviation/displacement.
Frequently there is still
contact between the
bone fragments
Spiessel and Schroll, 1972
10. Type III, high
condylar neck
fracture with
anterior, posterior,
medial, or lateral
deviation/displaceme
nt. As a rule, there is
no contact between
the fragments
Spiessel and Schroll, 1972
14. In addition, according to Lindahl (5), fractures of the
condyles can be classified into six classes, vertical slit
of the head (class I), horizontal break but mildly or not
displaced (II), displacement of the segments (III), there
may be medial overlap (IV) or lateral overlap (V) of
the displaced smaller proximal segment and a possible
partial or complete dislocation of the segment. Rarely,
fractures of the condyle may also be communited
(class VI) especially with gunshot injuries
15. History of falls, blows to the contralateral face or
ipsilateral preauricular area, or chin injuries should
alert the examiner to the possibility of a
condylar/subcondylar injury. Because of the U-shaped
mandibular anatomy, patients thought to have a single
mandibular fracture often have others. Also, the
patient with a subcondylar fracture often has another
mandibular fracture. Nevertheless, an isolated
subcondylar or intracapsular fracture is quite possible
16. By inspecting patients with a fracture of the mandibular condyle,
one or more of the following clinical signs and symptoms could
usually be noticed:
1) Swelling over the preauricular region
2) Possible bleeding from the ear
3) A laceration or contusion of the chin
4) Facial asymmetry due to soft tissue edema or secondary to
shortening of the mandibular ramus
5) Varying degree of limited mandibular movement
6) Pain and tenderness to palpation over the affected TMJ
7) Deviation of the mandibular midline with posterior open bite
8) Marked anterior open bite may indicate bilateral condylar
fractures
18. A fractured condyle does not translate down the articular
eminence on jaw opening. The unopposed translation of the
opposite condyle deviates the chin toward the fractured side
19. A fractured condyle usually is distracted antromedially by the lateral
ptergoid muscle. This produces a shortened functional height of the
ramus by the pull of the elevator muscles. The ipsilateral molar teeth
act as a fulcrum to produce a slight contralateral anterior open bite
20. Plain radiography (most commonly) and CT scanning
help to ascertain the location of the fracture, the
degree and direction of displacement, and the presence
or absence of associated injuries. Panoramic
radiography is a useful study. Anteroposterior (AP)
Towne’s view is particularly helpful for ascertaining
the mediolateral position of the respective fractured
segments, information not readily available from a
panoramic view
23. CT scanning in axial and coronal planes can yield
much information about this area provided that the
sections are sufficiently close to obtain images of the
area and provided the practitioner is intimately
familiar with the pertinent anatomy. CT scanning does
provide the most information about intracapsular
fractures
26. Treatment ranges from observation, jaw exercises to
closed or open interventions (6). In almost every instance,
unless associated with other mandibular fractures, isolated
intracapsular fractures, should be treated solely with
physical therapy. If properly rehabilitated, most of the
patients regain proper occlusion and full range of
mandibular movements. In the early rehabilitative phase,
controlling the occlusion (usually by means of arch bars
and elastics) while emphasizing return of normal range of
motion is important. The patient should be instructed in
wide range of motion exercises immediately post injury
27. Treatment of subcondylar condyle is among the most
controversial issues in maxillofacial trauma (7).
Ideally, treatment of condylar fractures must realize
three main aims: consolidation of the bony fragments ,
anatomic correction of the segments, and restoration
of joint function which typically involves pain-free
movement mouth opening beyond 40 mm. and the
restoration of the preoperative occlusion and facial
symmetry. Of these three goals, the restoration of joint
function is the most important (8)
28. For years, closed treatment using inter maxillary
fixation was the preferred method of treatment and
was thought to be essentially complication free.
Basically, the technique is conservative nonsurgical
one. Thus it eliminates the need for hospital stay and
prevents the possible intra and postoperative
complications associated with open reduction, namely
bleeding, infection, auriculotemporal nerve injury,
facial nerve paralysis, and visible scaring. Although
anatomic reduction is not possible with closed
reduction, it was believed that the selective exercises
lead to functional adaptation and remodeling of the bony
structures and the surrounding soft tissues (9)
29. For closed reduction, intermaxillary fixation is conducted using
arch bar and wire, followed by maintaining of the fixation of
the maxilla and mandible for 2 to 4 weeks. Elastic traction is
then used for additional 2 weeks to maintain normal occlusion.
Aggressive physical therapy and close follow-up is then
conducted for a period of 6-12 weeks. Closed reduction is
indicated for pediatric and geriatric patients and for medically
compromised patients as well. Of the utmost importance for all
patients, is the physical therapy regimens. Physical therapy
consists of a series of opening exercises. Some devices on the
market, such as the Therabite, can assist a patient with these
exercises. An alternative and inexpensive method consists of a
stack of tongue blades that can be increased in number each
day
30.
31. However, serious complications have been reported in
cases treated with closed reduction including,
temporomandibular Joint ankylosis, malocclusion,
mandibular deviation, and pathological changes to the
condylar process (10). Further, it has been noted that
patients treated by closed methods, compared to those
treated by open methods, developed asymmetries
characterized by significantly shorter posterior facial
and ramus heights on the side of injury, and more
tilting of the occlusal plane (11)
32. Open reduction means principally, exact anatomical
reduction under direct vision and at the same time
retention and internal fixation of the fracture by means of
functionally stable osteosynthesis.
Zide and Kent (12) summarized the indications for treating
subcondylar fractures in open manner as absolute and
relative:
Absolute Indications:
a. Displacement into the middle cranial fossa
b. Impossibility of obtaining adequate occlusion by closed
reduction
c. Lateral extracapsular displacement of the condyle
d. Invasion of a foreign body (e.g.: gunshot wound)
33. Relative Indications:
a. Bilateral condylar fracture in edentulous patients
when splinting is impossible
b. Unilateral or bilateral condylar fractures when
splinting is not recommended for medical reasons
or adequate post operative physiotherapy is
impossible
c. Bilateral condylar fractures associated with
comminuted mid-facial fractures
d. Bilateral condylar fractures associated with
significant pre-injury malocclusion
34. Multiple approaches are possible in order to visualize and
reduce submandibular fractures. Extraoral approaches
include the preauricular, retroauricular, retromandibular,
and submandibular incisions, often in combination.
Intraoral approaches include the mandibular vestibular
incision with or without the use of an endoscope. In both
cases, a transbuccal trocar for the placement of some or all
of the screws is usually necessary. Whatever approach is
chosen, once the fracture is exposed, it must be reduced.
Whether the fracture must be fixated and how stable that
fixation should be are also topics of much debate
35. Wire fixation and intramedullary pins have been used
to stabilize these fractures. More recently, miniplates
and screws are in use. Argument exists as to whether
these constitute rigid fixation. Certainly, a miniplate
that rigidly fixates the condylar segment in a
nonphysiologic position sets up the patient for pain,
poor function, and degenerative joint disease. Again,
occlusal control and physiotherapy remain crucial to
successful outcomes
36. position of two plates used to stabilize a subcondylar fracture
37. The debate between the supporters of open or closed
reduction is still continuing and the issue has not been
resolved. At present, except for the highly located
intraarticular fractures, open surgery appears to be the
main stream approach for treating mandibular fractures at
the condylar neck or subcondylar level. However, the final
choice of treatment modality for each individual patient
should takes into account a number of factors, including
position of the condyle, location of the fracture, age of the
patient, presence or absence of other associated injuries,
presence of other systemic medical conditions, history of
previous joint disease, cosmetic impact of the surgery, and
desires of the patient
