Mb. Naguib et al., SURGICAL ANATOMY OF THE PETROUS APEX AS IT RELATES TO THE ENLARGED MIDDLE CRANIAL FOSSA APPROACHES, Otolaryngology and head and neck surgery, 111(4), 1994, pp. 488-493
This work was designed to study the surgical anatomy of the petrous ap
ex as it relates to the enlarged middle cranial fossa approaches, on 2
5 temporal bones. In this study we suggest dividing the petrous apex i
nto two topographic areas: an anterior triangular and a posterior quad
rangular area with respect to the posterior border of the Gasserian ga
nglion. Anatomic descriptions endorsed by relevant measurements of the
se areas are provided in this study.
