Anatomy and Physiology
The endolymphatic sac is an extension of the membranous labyrinth, located in the posterior part of the temporal bone. It regulates endolymphatic fluid pressure and volume, crucial for inner ear function.

Endolymphatic sac surgery is primarily indicated in the treatment of Meniere's disease, believed to be related to an imbalance in endolymph production and absorption.
Endolymphatic sac surgery aims to reduce endolymphatic pressure through decompression or diversion of fluid. It may involve exposing the sac by removing bone and dura, followed by shunt placement or sac decompression.
