Of the 50 cerebellopontine angle tumors diagnosed during a three and one half year period, 36 were removed (all totally) using one of the three approaches to the cerebellopontine angle. Six patients, all elderly (over age 70) with obstructive hydrocephalus and complicating medical problems, had ventriculoperitoneal shunts inserted. One of these subsequently required tumor excision 10 months later. Of the 35 patients with normal functioning facial nerves pre-operatively, 34 (97 per cent) had the nerve spared surgically. Of 12 patients in whom hearing conservation was attempted, the cochlear nerve was spared in eight. However, useful hearing was preserved in one, with sound appreciated only in another.
在三年半的时间里诊断出的50例桥小脑角肿瘤中，36例通过三种桥小脑角入路之一被全部切除。6例患者均为老年（70岁以上），伴有梗阻性脑积水及其他复杂的医疗问题，接受了脑室腹腔分流术。其中1例患者在10个月后需要进行肿瘤切除。术前面神经功能正常的35例患者中，34例（97%）的神经在手术中得以保留。在尝试保留听力的12例患者中，8例的蜗神经得以保留。然而，只有1例患者保留了有用听力，另1例仅能感知声音。
