Approximately 10% of patients suffered from persistent vertigo, despite an optimal conservative treatment, are considered as intractable MD.1 To date, many methods have been attempted to treat these patients, including a variety of surgeries: selective vestibular neurotomy, labyrinthectomy and endolymphatic sac surgeries. The surgery can block the movement of endolymph in the canals to eliminate vertigo attacks induced by position changing Patients with advanced-stage MD suffered more from hearing deterioration postoperatively.
