Vestibular neurectomy was performed on a 42 year-old man with left Meniere's disease. The patient had been suffering from persistent vertigo attacks with left tinnitus. Neurectomy was performed using Silver-stein's retrosigmoid approach. An ABR and a Silverstein's nerve stimulator monitor were used to monitor cochlear and facial nerve function during surgery. The vestibular nerve and the cochlear nerve were separated along the cleavage plane, and the vestibular nerve was cut preserving the cochlear nerve. Facial nerve function was complete after the surgery. The average hearing level was 61.7dB before the surgery, and 53.3dB after the surgery. No vertigo attack has been noted after the surgery, and the patient has returned to work. Vestibular neurectomy is considered to be a very effective treatment for persistent Meniere's disease.
