| Popis: | The orbit represents one of the most complex anatomical structures in the body, tightly packed with critical neurovascular elements and surrounded by a well-organized system of muscles, bone, fat, and connective tissue. The orbit, and more specifically the optic nerve and central retinal artery, can serve as a central gateway or landmark to guide surgical approaches to the intraorbital and exo-orbital space (i.e. anterior cranial base). Orbital anatomy and approaches can be organized in a 360° orientation, based on the relative position of the optic nerve and the central retinal artery, and is separated into the following corridors (intra- and exo-orbital extensions): 1) Superior (transciliary, supraciliary, and frontoorbital), 2) Inferior: endoscopic endonasal approach (EEA) transmaxillary, 3) Lateral (superior lateral orbitotomy, pterional and orbitozygomatic), and 4) Medial (EEA transorbital and superior medial orbitotomy). Based on our experience and as described by Dr. Rhoton, a thorough knowledge of intraorbital anatomy for the neurosurgeon is perhaps more important when the pathology extends into the adjacent cranial base (or vice versa) or when intraorbital nerves and arteries (i.e. optic nerve and ophthalmic artery) are projecting into the anterior cranial base, requiring careful management of these structures. Regardless of the surgical approach taken to the intraorbital space or its exo-orbital projections, we advise the surgeon to act judiciously and practically, focusing on patient well-being. |
