title: Surgical anatomy of the petrous apex as it relates to the enlarged middle cranial fossa approaches.
abstract: This work was designed to study the surgical anatomy of the petrous apex as it relates to the enlarged middle cranial fossa approaches, on 25 temporal bones. In this study we suggest dividing the petrous apex into two topographic areas: an anterior triangular and a posterior quadrangular area with respect to the posterior border of the Gasserian ganglion. Anatomic descriptions endorsed by relevant measurements of these areas are provided in this study.
