Endoscopic management of benign tumors extending into the infratemporal fossa: a two-surgeon transnasal approach.

Abstract

Preliminary results of the endoscopic two-surgeon technique for the management of benign infratemporal fossa tumors are presented. Four patients with juvenile nasopharyngeal angiofibroma, a patient with an inverting papilloma, and a patient with a maxillary nerve schwannoma were reviewed. The average age was 22.7 years; the male-to-female ratio was 5:1. The endoscopic anatomy and surgical technique are presented. The two-surgeon technique allowed complete resection of all six tumors extending into the infratemporal fossa. There has been no recurrence of tumor within the infratemporal fossa, after a mean follow-up of 31.3 months (SD = 11.2 mo). The two-surgeon transnasal technique allows benign infratemporal fossa tumors to be resected endoscopically.
