Morphometric analysis of internal acoustic meatus

To study the morphometric analysis of internal acoustic meatus.

The internal acoustic meatus (iam) is a short bony canal that lies between the posterior surface of the petrous pyramid and the bony labyrinth within the dense petrous part of the temporal bone. The cn vii (facial nerve), cn vii (vestibulotrochlear nerve) and labyrinth vessels pass through the internal acoustic meatus. The internal acoustic meatus is important as a region in which acoustic neuromas occur.
