Orbital fractures involve breaks in the bones surrounding the eye socket. The orbit is formed by 7 bones and contains important structures. Types of fractures include those of the orbital floor, walls, and roof. Signs may include bruising, double vision, and numbness. Evaluation involves imaging like CT and examining for vision and eye muscle issues. Treatment depends on severity but may involve monitoring, antibiotics, steroids, or surgery to repair the fracture. Surgical risks include infection, numbness, and rarely blindness.

Orbital Fractures - The Role of an OphthalmologistAnkit Punjabi
Orbital fractures are a common finding in maxillofacial trauma. although a multi-disciplinary approach is essential, the role of ophthalmologist cannot be overemphazised. here we discuss the same.
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.

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.

3. Topics for Discussion
• Orbital anatomy
• Types of fractures
• Signs and symptoms
• Management
3
4. Orbital Anatomy
• The bony orbit refers to the shell of bone
which surrounds and protects the eye.
• The bony orbit is a pyramidal cavity with an
elliptical base presenting anteriorly and the
apex posteriorly
4
8. Superior Orbital Wall
• Formed by:
– Frontal bone
– Lesser wing of sphenoid
• Functions as:
– Floor anterior fossa
• Important structures:
– Supraorbital notch which transmits the
supraorbital nerve
8
9. Medial Orbital Wall
• Formed by (from anterior to posterior):
– Maxilla
– Lacrimal bone
– Ethmoid
– Sphenoid
• Important structures:
– Lamina papyracea
9
10. Lamina Papyracea
• Thin segment of the medial orbital wall
• Separates the orbit from the ethmoid air cells
10
12. Orbital Floor
• Formed by:
– Maxilla
– Palatine
• Important structures:
– Infraorbital groove
• Transverses floor from lateral to medial
• Location of infraorbital nerve which supplies sensation
to check and ipsilateral upper alveolus and teeth
12
13. Orbital Floor
• Forms roof of maxillary sinus
• Location of more blow out fractures due to
inherent weakness of bone overlying maxillary
sinus
13
14. Three important apertures at the
apex of bony orbit
• Optic canal
• Superior orbital fissure
• Inferior orbital fissure
14
19. Clinical Correlation
• Superior orbital fissure syndrome
– Ptosis
– External Ophthalmoplegia ( III, IV &VI )
– Anaesthesia of cornea (Nasociliary)
– Ipsilateral Numbness forehead, lateral orbital skin
• Orbital Apex Syndrome
– All of the above
– Visual Loss
19
20. Inferior orbital Fissure
• Connects to pterygopalantine fossa
• Located between floor and lateral wall
• Transmits:
– Maxillary division Trigeminal nerve
– Infra orbital Artery
– Zygomatic Nerve
– Sphenopalatine Ganglion Branches
– Ophthalmic Vein Branches
20
21. Blowout Fractures of Orbit
• Originally defined as orbital floor fractures
without fracture orbital rim, but with
entrapment one or more soft tissue structures
21
22. Blowout Fractures
• Blowout fractures now refer to fractures of the:
– Orbital floor
– Medial wall
– Lateral wall
– Superior wall
• “pure” blowout fractures – trapdoor rotation to
bone fragments involving central area of bone
• “impure” fracture – fracture line extends to orbital
rim
22
23. Physiology of Blowout Fracture
• The bony defect is filled with soft tissue and
fat from the orbit
• Alters support mechanisms for EOM
• EOM can become entrapped
• Direct muscle damage can result
23
24. Common causes of orbital
fractures
• Falling
• Aggression
• Sporting events
• MVAs
24
27. Initial Evaluation
• History
– Time and mechanism of injury
– Change in appearance of eye
– State of vision immediately after injury
• Immediate loss of vision – severe damage to retina
• Loss of light perception - vascular occlusion or optic nerve
compression
• Initial good vision – compression optic neuropathy
27
39. Initial Management
• ABC
• C-Spine
• Analgesia
• Nurse Head up
• Ice affected area
• Broad spectrum antibiotics
• Steroids
• No nose blowing

40. Indications for Surgery
• Retrobulbar haematoma
• Diplopia
• Enophthalmos >2 mm
• Substantial soft tissue herniation into
maxillary sinus
• Displaced fracture esp if palpable step at rim
40
41. Contraindications to surgery
• Hyphema
• Retinal detachment
• Globe perforation
• Only seeing eye
• Medically unstable patient

43. Factors to consider for surgery
• Site
• Location
• Severity
• What needs to be corrected
43
44. Orbital Implants

– Alloplastic material
• Teflon
• Marlex
• PDS
44
45. Complications of Surgery
