OBJECTIVES: The aim of this study was to provide the anatomic rationale for a transnasal approach to the orbital apex and cavernous sinus, and to evaluate its applicability and efficiency. METHODS: One hundred patients with lesions of the orbital apex, cavernous sinus, optic nerve, clivus, parapharyngeal space, infratemporal fossa, or pterygopalatine fossa were reviewed over a 10-year period. All patients underwent an endoscopic transnasal approach to the orbital apex and cavernous sinus. The surgical technique required a standard endoscopic sinus surgery set. The possible complications were recorded and classified as intraoperative or postoperative. RESULTS: There were complications in 8 cases: 4 intraoperative and 4 postoperative. The intraoperative complications included rupture of the internal carotid artery in 1 patient and cerebrospinal fluid leak in 3 patients. All intraoperative complications were resolved during surgery. The postoperative complications were transitory eyelid ptosis in 2 patients (resolved in 6 months) and transitory diplopia with immediate deficit of the medial rectus muscle in 2 patients (completely resolved in 1 month). CONCLUSIONS: With the use of this technique, the surgeon can precisely identify the position of the surgical instrument without losing his or her way, thereby significantly reducing the rate of complications.
