When hearing is poor and not worth saving, labyrinthectomy is a recommended treatment for controlling vertigo. The procedure involves removal of the inner ear membranes, once again to keep the abnormal inputs from the diseased inner ear from reaching the brain. The surgery can be performed through the ear canal or through a mastoidectomy approach. The vertigo cure rates are very high, but complete loss of hearing in the treated ear is expected since the inner ear is destroyed. A short period of vertigo is expected after the operation, and for this reason patients are kept in the hospital and treated with anti-vertigo medications for usually 1-3 days after the operation. Vestibular therapy hastens recovery of balance function following the surgery.
