Volumetric analysis of endoscopic and traditional surgical approaches to the infratemporal fossa.

Objectives/hypothesis: In an effort to decrease morbidity, skull base surgeons have explored less invasive approaches to the infratemporal fossa, including endonasal-endoscopy, minicraniotomies, and transantral endoscopic and microscopic corridors. This project presents quantitative data that assesses the practicality, and volumetric exposure afforded by endonasal and open approaches to the infratemporal fossa.

Study Design: First, the study defines the anatomy of endoscopic-endonasal and preauricular approaches to the infratemporal fossa.
