乳突切迹与侧颅底重要结构的解剖学观测及应用

目的:通过测量乳突切迹与侧颅底重要骨性结构的距离,为临床相关应用提供解剖学参考。方法:取成人颅骨标本50例(去颅盖标本8例,整颅42例)100侧,测量乳突切迹及其与侧颅底重要孔、裂和管的距离。结果:左右侧乳突切迹后缘距茎乳孔、颈静脉孔外侧缘、颈动脉管外口后缘、破裂孔、棘孔、卵圆孔距离分别为25.16±3.73cm和25.02±3.58cm、30.92±3.50cm和30.45±3.49cm、38.22±3.57cm和38.14±3.43cm、57.23±3.71cm和57.14±3.44cm、47.94±3.83cm和48.32±3.54cm、53.70±3.98cm和53.55±3.75cm。结论:以乳突切迹后缘做为侧颅底手术的定位标志能够为临床相关应用提供较方便、准确的定位参考。

The anatomical observation and application of the mastoid incisure and lateral-basalis important structures

Objective:By measuring the distance of mastoid incisure and the importance of lateral skull base bone structure,to provide the anatomical reference for clinical relevant applications.Method:A total of 50 cases of adult skull specimens were taken(8 remove calvaria specimens,42 cases of entire cranial) 100 sides,measuring the distance of mastoid incisure and the important holes,cleft and tube distance of lateral skull base.Result:The distance of Posterior margin of left and right side mastoid incisure to styl...
