  Objective: Optimal surgical indications for cochleovestibular neurovascular compression syndrome (CNVC) remain controversial. We examined the surgical indications and timing of surgery for CNVC. Methods: The surgical outcomes of 30 patients (32 sides) with vertigo, tinnitus and hearing loss were evaluated. CNVC was diagnosed according to five items for clinical features with a scoring system of 1 or 0 based on the following features: a history, neurological and otological findings, an ABR evaluation, and vascular contact with the eighth cranial nerve on MR or air CT imaging. Patients with scores of 4-5 were diagnosed with CNVC. In addition, three modulation types of tinnitus using median nerve stimulation were evaluated in CNVC (28 sides) and other diseases (12 sides), and classified as suppression (S-type), no change (N-type), and excitation (..
