Abstract
The orbit is a natural bony cavity communicating with extracranial and intracranial spaces through three openings: the superior orbital fissure (SOF), which connects the orbit with the middle cranial fossa; the inferior orbital fissure (IOF), which connects the orbit with the pterygopalatine, infratemporal, and temporal fossae; and the optic canal (OC), which connects the orbit with the supratentorial intradural space (Fig. 3.1) [1]. A detailed knowledge of the microsurgical anatomy of these bony openings, their contents, and the anatomical relationships of the encased structures is necessary for safe surgery, whether to or through the orbit.
