This document summarizes a study on correcting deviated nasal septums through septoplasty with turbinoplasty and the use of an intranasal flexible plastic splint. The study was conducted in Libya from 2012-2014 and included 75 patients, most of whom were male. Deviated nasal septums were diagnosed using various examination techniques and treated with septoplasty, turbinoplasty, and insertion of an intranasal splint. Patients who received the splint recovered faster with fewer complications like synechia formation. The study concludes that combining septoplasty with turbinoplasty and use of an intranasal splint improves outcomes by reducing complications and allowing for faster recovery.

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.

Background: Septoplasty is a common surgical
procedure performed by otolaryngologists for the correction of
deviated nasal septum. This surgery may be associated with
numerous complications. To minimize these complications,
otolaryngologists frequently pack both nasal cavities with
different types of nasal packing. Despite all its advantages,
nasal packing is also associated with some disadvantages. To
avoid these issues, many surgeons use suturing techniques to
obviate the need for packing after surgery.
Objective: To determine the efficacy and safety of trans-septal
suture technique in preventing complications and decreasing
morbidity after septoplasty in comparison with nasal packing.
Patients and methods: Prospective comparative study. This
study was conducted in the department of Otolaryngology -
Head and Neck Surgery, Rizgary Teaching Hospital - Erbil,
from the 6th of May 2014 to the 30th of November 2014.
A total of 60 patients aged 18-45 years, undergoing septoplasty,
were included in the study. Before surgery, patients were
randomly divided into two equal groups. Group (A) with transseptal
suture technique was compared with group (B) in which
nasal packing with Merocel was done. Postoperative morbidity
in terms of pain, bleeding, postnasal drip, sleep disturbance,
dysphagia, headache and epiphora along with postoperative
complications including septal hematoma, septal perforation,
crustation and synechiae formation were assessed over a follow
up period of four weeks.
Results: Out of 60 patients, 37 patients were males (61.7%)
and 23 patients were females (38.3%). Patients with nasal
packing had significantly more postoperative pain (P<0.05)><0.05). There was no significant difference between
the two groups with respect to nasal bleeding, septal
hematoma, septal perforation, crustation and synechiae
formation.
Conclusion: Septoplasty can be safely performed using transseptal
suturing technique without nasal packing.
Any deviation in the normal nasal septum is called DNS (Deviated Nasal Septum).
Deviated Nasal Septum may be caused by mechanical trauma and may be
associated with some developmental defects.

Complications of lower anterior implants| Complications of Dental Implants by...Dr. Rajat Sachdeva
Implants are tooth-root like structure place beneath the jaw-bone.
although it is best replacement of natural teeth, complications are still there, surgical complications like hemorrhage and hematoma neurosensory disturbance and damages of adjacent teeth which occurs due to in-proficient surgical exercise.
Biologic complication like inflammation dehiscence and recession periimplantitis and bone loss occurs due to patient's ignorance of hygiene.
Technical Complication like implants fracture, screw loosening, prosthesis fracture.
and some miscellaneous complication, which occurs and should care as soon as possible.
An impeccable procedure is needed to perform a perfect Implants procedure.

Emergency management of patients with facial trauma
Dr. Ahmed M. Adawy Professor Emeritus, Dept. Oral & Maxillofacial Surg. Former Dean, Faculty of Dental Medicine
Al-Azhar University.
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.
Background: Septoplasty is one of the commonest nasal surgeries
performed by otolaryngologist. Silicone is the most common
material used for nasal splints. Trans-septal suturing technique
has been described to approximate the mucosal flaps after septal
procedures to reduce the complication rate; however there are
few studies proving the efficacy.
Objective: This study is to elucidate the efficacy of trans-septal
suture method in preventing complications, discomfort and pain
in comparison with intranasal splinting using silicone plates after
septoplasty.
Patients and methods: This is a prospective study of 59 adult
patients underwent Septoplasty, between August 2013-January
2014 in Rizgary Teaching Hospital - Erbil city. Patients were
divided into 2 groups; trans-septal suture and silicone, 29 and 30
patients respectively. Visual analogue scale was used to evaluate
postoperative pain, bleeding, post-nasal drip, dysphagia and
sleep disturbance for three days. Epiphora and septal hematoma
are also evaluated. Septal perforation, crustation, and adhesion
were evaluated at 4th postoperative week.
Results: The severity of pain and post nasal drip were
significantly lower in trans-septal suture group than silicone
group (P< 0.05). The septal hematoma and septal perforation
were not seen in the study. No any significant difference found
concerning epiphora, crustation and adhesion.
Conclusion: we conclude that, suturing can be used safely in
septoplasty sp

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.

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!

sinusitis, facial pains, headache, postnasal drip, noisy breathing during sleep etc. Aim of this study is to improve
the surgery procedure with the use of intranasal flexible plastic splint and fast recovery of DNS patients from
blockade and free of synechia formation in the nose and breathe freely and improved drainage.
Deviated Nasal Septum (DNS) study was conducted at Al-khoms teaching hospital, Al-khoms, Libya for 3 years
from 2012 to 2014. 75 cases were admitted with DNS problems during the study. DNS was diagnosed with the
help of Head lamp, anterior and posterior rhinoscopy and a nasal speculum and confirmed with PNS X-ray and
CT- Scan. Septoplasty is one of the most common surgical procedures in the speciality of Otorhinolaryngology.
Septoplasty was performed with Turbinoplasty (partial bilateral inferior turbinectomy) and intranasal flexible
plastic splint.
Among the admitted 75 in-patients, there were 64 (85%) male patients and 11(15%) female patients with DNS
problems. These DNS were noted more in the adult male than female. The result, more DNS in the male adult
indicate in the present study mainly that these DNS may be due to nasal trauma or the trauma in the childhood
can cause the DNS in the adult life because any degree of septal deviation usually becomes more pronounced
with time in septoplasty. The time taken to recover was 2-3 weeks with proper daily nasal care. But 13 cases
had partial nasal obstruction and development of intranasal small adhesion between lateral nasal wall and
septal wall (Synechia).
The study indicates that male has more DNS problems than female. Septoplasty with Turbinoplasty and intra
nasal flexible plastic splint reduces the Synechia formation and intranasal haematoma. This improves the
overall health of DNS patients to lead the fast recovery for free breathe and quality life.
Key Words: Deviated nasal septum, Synechia, Septoplasty, Plastic splint.
I. Introduction:
The nasal septum is a composite plate like structure made up of membrane, bone and cartilage. The
nasal septum divides the two halves of the nose into right and left nasal cavities. In Deviated nasal septum
(DNS), nasal septum is ideally central and slightly deviated to one side or the other (Moore, 1994). DNS can
occur either in developmental during origin, over period of time or by trauma such as a hit, sport trauma or an
accident. Mladina and Subaric (2003) categorized the Posterior septal deformities are inherited and an anterior
deformities are caused by environmental factors like injury in the nose and the central massif of the face.
Takahashi (1977) expressed that man seems to be the only mammal species in which deformation occurs.
Frequency of nasal septum deformation is determined by the genetic, cultural and environmental factors. Types
of DNS are based on the shape of the deviation, parts of the septum deviated and location of the deviation.
Deviation of the septum may be in the form of a “C” or S shaped; bony and cartilaginous or mixed type of
deviations. Sometimes High DNS or Caudal deviations (Donald, 1994). These changes may change the function
of septum in the nose like warming, humidity, filtering, olfaction and phonation (Kosama et al., 2005).
Septoplasty is one of the most common surgical procedure in the speciality of Otorhinolaryngology
(Nunes et al.,2000). Therefore there are frequent thoughts among ENT specialists regarding to improve this
procedure in different aspects, indications, time of surgery, techniques, safety measures and post operative care.
One of the big issues regarding this procedure is the post-operative sequel and complications of developing
Synechia, oro-facial odema, air way obstruction, disturbing the drainage, epistaxis, nausea and vomiting, atropic
rhinitis, induction of allergic rhinitis, septal perforation and post operative pain (Bofares, 2013).
Aim of this study is to improve the surgery procedure with the use of intranasal flexible plastic splint
and fast recovery of DNS patients from blockade in the nose and breathe freely and improved drainage.
II. Materials and Methods:
The study was conducted at Al-khoms Teaching hospital, Al-khoms, Libya from 2012 to 2014. 75
cases (64 male and 11 females) with DNS problems, between the age group of 10 and 40 were admitted in this
study. The patients (all in-patients) for nasal septal surgery were informed and collected the consent of the

patient and his/her parents. Patients with Hypertension and Diabetes were excluded. Cases were grouped into
with or without intranasal plastic splint.
DNS was diagnosed with the help of Head lamp, Anterior and posterior Rhinoscopy and a Nasal
speculum and confirmed with PNS X-ray and CT- Scan. Septoplasty was performed with Turbinoplasty (partial
bilateral inferior turbinectomy) and intranasal flexible plastic splint (Folien plastic splint). Surgery was done
under general Anesthesia with partial bilateral inferior turbinectomy to remove the nasal obstruction. The
intranasal plastic splint was kept inside and sutured within the nose after surgery by the Hemitransfixation
procedure. The splint was fixed not tight by needle and suture to avoid the pressure necrosis.
Post operative care was followed once in a day. Nasal care in the form of suction clearance of nose
with the help of spray with the mixture of 2% Xylocain (local anesthesia), Otrevin and diluted Adrenaline.
After 3 post operative days, the intranasal flexible plastic splint was removed. In 4-6 days, patients were allowed
to go home and asked them to come for the follow-up daily once in a day for post nasal care.

Septoplasty is the most common surgical procedure in the speciality of ENT. Post operative problem is
a significant problem that lead to the inability to tolerate the pain and feelings. Among the admitted 75 in-
patients, there were 64 (85%) male patients and 11(15%) female patients with DNS problems. These DNS were
noted more in the adult male than female. Similar result was also observed in Poland (Tuel et al., 2009) and in
Croatia (Subaric and Mladina (2002). The result, more DNS in the male adult indicate in the present study
mainly that these DNS may be due to nasal trauma by a hit, sports trauma, physical activities of boys or an
accident or the trauma in the childhood can cause the DNS in the adult life because any degree of septal
deviation usually becomes more pronounced with time. But the result of Rehman et al., (2012) showed
contradictory to the present study that the females have more prevalence of DNS. In 56 (Cartilagenous DNS)
cases, 39 cases of male and 4 cases of females with intranasal flexible splint and 10 male and 3 females without
intranasal flexible splint. Remaining 19 cases were having the Carilagenous and bony combined type of DNS.
All cases with usage of splint were recovered fast and felt ease in the post operative care. Musani et al.,(2012)
also have observed positive correlation between the improvement of quality of life and septal surgery. But 13
cases from the without intranasal flexible plastic splint group, have observed the development of intranasal
small adhesion between lateral nasal wall and septal wall (Synechia) and intranasal septal haematoma. Due to
this haematoma, there was a development of septal abscess and delay in the recovery. Baljosevic et al., (2011)
were done the same procedure with children in Serbia for early correction and cosmetic nose deformities. One
case was with septal perforation and another case with abscess was observed. The time taken for recovery was
2-3 weeks with proper daily nasal care. So the cases with intranasal flexible plastic splint, have recovered fast
without any synechia formation. Dalal et al.,(2013) have used endoscopic approach to the septoplasty to reduce
the operative time and improve the surgical outcome.
IV. Conclusion:
As the Septoplasty is one of the common procedures in ENT speciality, the combined procedure with
Turbinoplasty and usage of intranasal flexible plastic splint has improved the septoplasty procedures by
reducing the Synechia and intranasal septal haematoma and abcess, which in turn speed up the recovery of
patients and reduce stay in the hospital and medical expenses. Continuous researches are recommended to
resolve all the problems which are associated with it.
