1 概述 目前,听神经瘤和其它桥小脑角肿瘤手术切除主要有3种基本入路。 枕下入路方便快捷,但需将病人置于侧卧位、坐位或半坐位,需不同程度牵拉小脑(肿瘤较大时对小脑的损伤更为明显),尚有空气栓塞风险和术后颈痛、顽固性头痛的可能。尽管如此,多数术者仍偏爱此入路,因为各种类型桥小脑角肿瘤,不论大小,经此入路手术均有利于保留听力。
1 Overview At present, there are three basic approaches to surgical resection of acoustic neuroma and other cerebellopontine angle tumors. Suboccipital approach convenient and quick, but the patient needs to be placed in the lateral position, sitting or semi-sitting, to varying degrees, pulling the cerebellum (tumor larger damage to the cerebellum is more obvious), there are still the risk of air embolism and postoperative Neck pain, stubborn headache may be. Nevertheless, most surgeons still prefer this approach, because all types of cerebellopontine angle tumors, regardless of size, after this operation are conducive to keep the hearing.
