摘　　要：目的:探讨颞骨外段面神经干的定位方法。方法:对10例(20侧)成人头颅湿标本用上颈段侧方入路进行逐层解剖,观测颞骨外段面神经干与周围结构的毗邻关系。结果:颞骨外段面神经干位置恒定、暴露清晰,外耳道软骨尖距离面神经干(9.60±1.64)mm,鼓乳切迹内侧(12.26±2.14)mm为面神经干。结论:外耳道软骨尖、鼓乳切迹、二腹肌后腹及腮腺后上缘可作为颞骨外段面神经干的定位标志。Aim:To explore the method for locating extratemporal segment of facial nerve trunk.Methods:A total of 10 samples of adult cadaver heads(20 sides)were used for microsurgical dissection with a lateral approach on upper cervix,and the anatomy structures of peri-extratemporal segment of facial nerve trunk were observed.Results:The position of extratemporal segment of facial nerve trunk was invariable,and exposured clearly.The distance of extratemporal segment of facial nerve trunk to the tip of the tragal point...
