Abstract

Orbital surgery is one of the highly specialized branches at the crossroads of ophthalmology, neurosurgery and maxillofacial surgery. The orbit is a small space of 30 ml volume and is surrounded by bone, paranasal sinuses and cranial cavity. The complex of the eyeball and its neurosensory, motor and secretory appendages compacted within this small space, thereby posing a danger of functional impairment with slight mechanical insult. Surgery in this specialized area, therefore, lies in the domain of the experienced ophthalmic plastic surgeon that is familiar with the anatomy and physiology of the orbit and periorbital structures. Over the last three decades, advances in investigative techniques, anesthesia and surgical techniques have vastly improved the operative potential for orbital diseases. Radiologic procedures, such as computed tomography and magnetic resonance imaging, allow the ophthalmic surgeon to accurately localize the lesion and plan the surgical approach. The use of hypotensive anesthesia, intraoperative magnification and special instrumentation allows meticulous dissection of orbital structures.
