Transpterygoid Endoscopic Approach for Inverted Papilloma of the Sphenoid Sinus: A Case Report
Main Article Content
Abstract
We describe a clinical case of a woman with an inverted papilloma in the sphenoidal sinus.
The sphenoid was highly pneumatized, and the inverted papilloma extended into a lateral recess of the sinus beyond the paraclival segment of the internal carotid artery, which was prominent.
We performed a unilateral endonasal approach, combining a bilateral sphenoidotomy with a posterior septectomy and a transpterygoid approach to expose the lateral pneumatized recess of the sphenoid located behind the posterior wall of the maxilla.
We resected completely the inverted papilloma with no evidence of recurrence.
