目的探讨内所道桥小脑角肿瘤手术耳科进路的地位。方法１９９１～１９９６年期间采用迷路进路或迷路、乙状窦后联合进路手术的１１例内听道桥小脑角肿瘤术后２～７年的疗效进行分析。结果本组病例无１例死亡，术后面神经功能保存率高。结论迷路进路切除内听道桥小脑角肿瘤不需开颅，对脑干和小脑的损伤小，且可以从内所道底起解剖面神经，对面神经的损伤也小。此进路适宜直径＜３．５ｃｍ，患耳语言频率平均听阈大于４０ｄＢ的内所道桥小脑角肿瘤。 Objective To investigate the status of surgical otological approach to intracapsular cerebellar angle neoplasia. Methods The clinical data of 11 patients with cerebellopontine angle of the auditory canal during 2 years and 7 years after operation of labyrinthine approach or labyrinthine approach combined with posterior sigmoid sinus surgery were analyzed from 1991 to 1996. Results No case of death in this group of patients, facial nerve function preservation rate. Conclusions Lost pathology of intracranial cerebellar angle lesion without intracranial cranioplasty has less damage to the brain stem and cerebellum, and can dissect the facial nerve from the end of the tunnel and damage the facial nerve. This approach is suitable for diameter <3.5cm, suffering from hearing loss of the average hearing threshold frequency greater than 40dB of the intraocular bridge of the cerebellopontine angle tumors.
