Hearing changes and questionnaire responses in patients with paramedian suboccipital vestibular neurectomy

In order to determine the effectiveness of paramedian suboccipital transmea tal vestibular neurectomy, pre- and postoperative neurotological studies we re conducted and questionnaire responses of 30 patients who underwent surge ry were evaluated. Hearing was maintained within 10 dB of the preoperative level or improved in 54% of patients 2 years after surgery. Questionnaire r esponses indicated that all patients suffering from intractable vertigo exp erienced no vertiginous symptoms after surgery. Based on this study, we con clude that paramedian suboccipital transmeatal vestibular neurectomy is a u seful method for relieving ear-related vertigo.
