Quantitative Analysis of “Kawase's Triangle” versus “Modified Anterior Petrosectomy (MAP) Rhomboid” Approach for Extended Middle Cranial Fossa Lesions Extending into Posterior Cranial Fossa

Abstract

Objective: Extended middle cranial fossa approach with transtentorial extension (Kawase's Triangle approach) is an established operative technique for anterior petrosectomy. We used cadaveric model and performed computerized quantitative analysis to compare 'Kawase's' and 'Modified Anteior Petrosectomy (MAP) ie Dolenc's + Kawase's' approach for lesions around petroclival region.
