ANATOMY OF THE EAR  
THE INNER EAR

THE INNER EAR

Description : The inner ear is located deeply within the petrous part of the temporal bone and is beyond the range of the otoscope. However, modern diagnostic imaging techniques have improved our ability to inspect this region, thereby enhancing our understanding of the effects of both congenital and acquired disorders of hearing and balance.

A knowledge of the basic anatomy of the inner ear is required to appreciate both the mechanisms of normal inner ear function and the paths by which structural changes can result from diseases arising in the middle ear cleft or surrounding regions.

The inner ear consists of two parts-the bony labyrinth and the membranous labyrinth.The inner ear is located deeply within the petrous part of the temporal bone and is beyond the range of the otoscope.
