This frequently causes downward and forward displacement of the globe. The ultimate diagnosis is made by computed tomography ct of the face. Coronal slices hard tissue window of the same isolated right orbital roof fracture. Contrast is not needed.

Although sagittal sections are also helpful in some cases the axial images are less so. Fracture of the left zygomaticomaxillary attachmnet with fracture of the anterior and lateral maxillary walls inferior orbital rim fracture and left maxillary hemosinus. Once the orbital floor is exposed periorbital dissection is performed. Angulated displaced fractures fragments are seen projecting downwards within the orbit indenting the superior rectus muscle.

The following pages provide general information regarding orbital anatomy and dissection. Exposure of orbital roof fractures is normally via preexisting lacerations upper blepharoplasty incisionsor probably most often via coronal approach. Sagittal slices hard tissue window of an isolated right orbital roof fracture. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma.

Most orbital roof fractures are blow in fractures displacement of the bone is towards the orbit. When they do happen they may be associated with intracranial hemorrhages traumatic optic neuropathy and csf leakage into the orbit. It is more prevalent in young men.
