About the Procedure

A mastoidectomy is performed exposing the endolymphatic sac (a small structure attached to the inner ear that is responsible for fluid balance). A incision is created into the structure and a shunt is inserted allowing drainage of fluid when inner ear pressure is elevated. As the inner ear contains only a few drops of fluid, resorption of the fluid occurs in the mastoid cavity.
