Endoscopic Management of Benign Tumors Extending Into the Infratemporal Fossa: A Two-Surgeon Transnasal Approach

OBJECTIVES/HYPOTHESIS: Preliminary results of the endoscopic two-surgeon technique for the management of benign infratemporal fossa tumors are presented. METHODS: 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. RESULTS: 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). CONCLUSION: The two-surgeon transnasal technique allows benign infratemporal fossa tumors to be resected endoscopically.
