听神经瘤手术中的听力保护在少数病例中是可能的。虽然已经发表了许多关于听力保护的文章，但很少有关于长期听力结果的研究，也不知道在尝试听力保护时是否会增加肿瘤复发率。自1984年2月至1987年11月连续手术治疗桥小脑角肿瘤80例，其中22例行乙状窦后入路听力保留术。先前发表的一项研究报告称，11例患者保留了有用的听力。7名患者在3至5年后继续保持有用的听力；3名患者表现出逐渐但轻微的下降。这些患者没有肿瘤复发，但有2名患者在早期手术并失去了听力，出现了肿瘤复发。
Hearing preservation in acoustic neuroma surgery is possible in a limited number of cases. Although there have been many articles published about hearing preservation, there have been few studies of long-term hearing results, nor is it known if there is an increased rate of tumor recurrence when hearing preservation is attempted. Twenty-two patients who underwent a hearing preservation procedure via the retrosigmoid approach were selected from 80 consecutive patients with cerebellopontine angle tumors operated on from February 1984 to November 1987. Useful hearing was retained in 11 cases as reported in a previously published study. Seven patients continue to have useful hearing after 3 to 5 years; 3 have shown a gradual but slight decline. There has been no tumor recurrence in these patients, but 2 patients, operated on early in the series and who had lost hearing, had recurrent tumor.
