听神经瘤手术主要目的是彻底切除肿瘤和保留面神经功能。近10年来,对手术病人同时予以保存听力引起人们越来越多地关注。但除个别病例外,目前对此类病人的肿瘤复发率和听力保持的远期效果缺少研究。该作者自80例桥小脑肿瘤中选择22例行保存听力的手术。其中20例为听神经瘤,2例脑膜瘤。该组病人听力损失平均小于60dB,肿瘤小于2cm,均行枕下进路手术,所有术后保存听力的病人每年行纯音测听、语言测听、听性脑干诱发电位和CT检查。22例病人中11例术后有保存听力,在3～5年观察中,其中2人死于冠状动脉性疾
The main purpose of acoustic neuroma surgery is to completely remove the tumor and retain facial nerve function. In the past 10 years, the preservation of hearing loss for surgical patients has drawn more and more attention. However, with the exception of individual cases, there is currently no research on the long-term effects of tumor recurrence and hearing preservation on such patients. The author selected 22 cases of hearing preservation surgery from 80 cases of cerebellopontine brain tumors. 20 cases of acoustic neuroma, 2 cases of meningioma. The group of patients with hearing loss average less than 60dB, the tumor is less than 2cm, undergoing suboccipital approach, all patients with hearing preservation after each line of pure tone audiometry, audiometry, auditory brainstem response and CT examination. Of the 22 patients, 11 had preserved hearing after surgery and 2 of the 22 patients died of coronary artery disease in 3 to 5 years
