60年代初,House和Doyle将手术显微镜用于小脑桥脑肿瘤切除术并改进了手术径路。术后听力保存有了可能。Wade和House认为如果病人的纯音测听丧失50dB或更多,语言辨别率低于50％,这种听力无保存价值。Smith和Lagger认为如按这种标准来选择破坏听力还是保存听力的手术,则许多病人术后定将失去听力。因病人有可能患双侧小脑桥脑角肿瘤或对侧突发性聋。如采用破坏性手术,未将值得保存的残存听力保存下来,将导致双侧听力丧失。如彻底切除肿瘤,最好要保持内耳及听神
In the early 1960s, House and Doyle used a surgical microscope for resection of cerebellar pontine brain tumors and improved the surgical approach. Postoperative hearing preservation is possible. Wade and House argue that hearing loss is not preserved if the patient has 50 dB or more of pure tone audiometry and less than 50% speech recognition. According to Smith and Lagger, many patients are set to lose their hearing after surgery if they choose to undermine or preserve their hearing on this basis. Because of the patient may have bilateral cerebellar pontine tumor or contralateral sudden deafness. If destructive surgery is used, the residual hearing loss that is worth preserving will not result in bilateral hearing loss. Such as complete removal of the tumor, it is best to keep the inner ear and listen to God
