CT scan of the temporal bone demonstrating bony canal of the intratemporal part of the facial nerve red. The intratemporal part of the facial nerve has three segments: labyrinthine from IAC to geniculate ganglion , tympanic from geniculate ganglion to pyramidal eminence and mastoid from pyramidal eminence to stylomastoid foramen.

Anatomical Features of Intratemporal Course of Facial Nerve and its Variations

Facial nerve has the longest and complex course in its bony canal. The anatomical variations make the nerve prone to injury during mastoid surgeries. Having a thorough anatomical knowledge and its variations is must for the surgeons to avoid injury to this vital structure and for the safe surgery. The objective of the study was to describe the anatomical variations of intratemporal portion of facial nerve.
Objectives: To present the imaging findings and anatomical locations of a series of 88 facial nerve neuromas from two centers over a year period. We describe the salient radiological features of neuromas in each anatomical location and outline the ways in which modern imaging techniques have altered our perception of this entity. Study design: A retrospective review of tumors presenting to two tertiary care referral institutions since
