经乳突进路行内淋巴囊引流术来治疗美尼尔氏病,如缺乏局部解剖知识,手术不当,可引起严重并发症。为此,作者们对20例无耳病的尸体颞骨进行了该手术的局部解剖学研究。死者年龄为21～70岁。先在尸体颞骨上完成经乳突的内淋巴囊引流术。然后,在和环钻骨管轴垂直的平面,即和乳突平行的平面上分层锯开乳突,在手术显微镜下研究切面的局部解剖关系。结果如下:(1)从乳突皮质到内淋巴囊的平均距离为 The mastoid process line lymphatic drainage for the treatment of Meniere’s disease, such as the lack of local anatomy, improper operation, can cause serious complications. To this end, the authors performed a topical anatomic study of 20 cases of ear-free corpse temporal bones. The deceased is 21 to 70 years old. First in the body temporal bone through the mastoid endolymphatic drainage. The mastoid process was then stratified in a plane perpendicular to the pericardial axis, the plane parallel to the mastoid, and the anatomy of the section was studied under a surgical microscope. The results are as follows: (1) from the mastoid cortex to the average distance of the lymphatic sac
