Abstract
Hearing preservation in patients with vestibular schwannomas remains difficult by microsurgery or radiosurgery. In this study, awake surgery via the retrosigmoid approach was performed for vestibular schwannomas (volume, 11.6±11.2ml; range, 1.3-26.4ml) in eight consecutive patients with preoperative quartering of pure tone audiometry (PTA) of 53±27dB. After surgery, hearing was preserved in seven patients and improved in one patient. The postoperative quartering PTA was 51±21dB. Serviceable hearing (class A+B+C) using the American Association of Otolaryngology-Head and Neck Surgery (AAO-HNS) classification was preserved in all patients. Preoperative useful hearing (AAO-HNS class A+B) was observed in three patients, and useful hearing was preserved in all three of these patients after surgery. In addition, useful facial nerve function (House-Blackmann Grade 1) was preserved in all patients. These results suggest that awake surgery for vestibular schwannomas is associated with low patient morbidity, including with respect to hearing and facial nerve function.
