20世纪60年代美国House引进显微外科技术,开创了以听神经瘤切除术为代表的耳神经显微外科。此后,各国耳科专家在此基础上又衍生了多种进入内耳道、桥小脑角、岩尖和斜坡等难以到达的颅底深部手术入路。彻底切除内耳道肿瘤,完整保留和恢复面神经甚至耳蜗神经功能是此类手术治疗的理想结果[1]。但目前内耳道手术肿瘤全切率及术中面神经解剖及功能保留率不尽理想,仍是耳神经外科领域所面临的难题,其影响因素包括肿瘤的大小,肿瘤与面神经的关系,
The 1960s United States House introduction of microsurgery technology, created by the acoustic neuroma resection of the otoscope nerve microsurgery. Since then, the ear experts from all over the country have derived many kinds of intracranial deep intra-ear canal, bridge cerebellar angle, petrous apex and slope, which are difficult to reach. Thorough resection of internal ear tumors, complete preservation and restoration of facial nerve and even cochlear nerve function is the ideal result of such surgical treatment [1]. However, the total excision rate of intraoral canal surgery and the anatomic and functional retention rate of intraoperative facial nerve are still unsatisfactory, which are still the problems in the field of neurosurgery. The influencing factors include the size of tumor, the relationship between tumor and facial nerve,
