Endolymphatic Sac Decompression

Abstract

The endolymphatic sac (ELS) decompression can be performed for patients with Meniere’s disease that have failed conservative treatment such as dietary changes and medical therapy. The full pathophysiological mechanisms that result in Meniere’s disease are not entirely understood. The variation in techniques for performing ELS decompression support this; there is no concrete data to justify one approach over another. Regardless, in the correct patient, ELS decompression can significantly alleviate the patient’s symptoms. To do so, a mastoidectomy is performed to expose the bony labyrinth as well as the bone overlying the sigmoid sinus. Decompression of the sac can be accomplished by removing overlying bone, incising the dura, or stenting the dura open.
