摘要
为了探讨面神经颅外段的走行,对120例由于各种原因进行保留面神经的腮腺腺叶切除术的患者,在术中对其面神经出颅后的走行、分支及其与邻近组织的关系等进行了解剖测量观察。观测包括面神经主干的长度、宽度以及各个分支发出的部位,各个分支的解剖特点。结果表明:颞支位置深在,分支较多;颧支位置深在,较粗大,分支相对较少,位置恒定;颊支分为①上下颊支型;②融为一支型;③一支再分型三种情况;下颌缘支位置较表浅,较细且走行长,分支多为2~3支。对手术时如何利用邻近解剖关系正确地寻找面神经进行了分析。
To explore the course and anatomic characteristics of the extra-cranial section of the fa- cial nerve,the authors carried out this clinical study in 120 patients undergoing parotidectomy by dissect- ing and measuring the facial nerve and its branches,regarding its length,diameter and numbers.The re- sults confirmed that the temporal branch is deeper and has multiple branches;the zygomatic branch is bigger,with consistent location and fewer branches;the buccal branch exhibits three patterns:①the upper and lower branches,②one trunk and ③ one trunk with two or three branches;the marginal mandibular branch is a small and superficial with two to three branches.The authors discuss how to lo- cate the facial nerve accurately.
