Fracture Of The Orbital Roof

Non displaced isolated blow in isolated blow out or blowup supraorbital rim involvement without frontal. Approaches include extracranial intracranial and endonasal endoscopic. Orbital roof fractures are particularly important because of their association with intracranial injury.

There are several different configurations of orbital roof fractures including.

Fracture of the orbital roof.

Coronal slices hard tissue window of the same isolated right orbital roof fracture. The following pages provide general information regarding orbital anatomy and dissection. Dural tears are associated with csf leakage and pneumocephalus. This frequently causes downward and forward displacement of the globe.

The clinical picture is often multiple because of involvement of cranial cerebral and facial injuries. Bilateral orbital roof fractures are rare events usually associated with high energy impact trauma. Another mechanism of injury is a blow in fracture where there is an inferiorly directed supraorbital force. The approach used is determined by the surgical needs of the patient.

Fractures of the roof of the orbit are typically associated with trauma to the forehead frontal bone are are often extensions of superior orbital rim fractures. Isolated non displaced orbital roof fractures most commonly seen in children and rarely require surgical intervention. Orbital roof fractures are more common in childhood as the frontal sinus has not yet pneumatised therefore all posterior force to the superior orbital rim is transferred to the anterior cranial base. When the inner table of the orbital roof is not involved and there is no dural tear the orbital fracture can be accessed by superior orbitotomy.

The primary diagnostic and therapeutic approaches aim to safeguard the cerebral state and to intercept the consequences of severe orbital trauma. Once the orbital floor is exposed periorbital dissection is performed. Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach. Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit.
