摘要
用35例成人头面部标本,对面神经颞支的额肌神经进行了观察。额肌神经共出现61支,每例1.8(1～3)支。该神经入肌点支数为7.75～13支。入肌点分布在耳屏(T点)与眼外眦(L点)两点连线(SL线)上方,距 TL 线28.9±4.3～50.9±7.6mm之间。额肌神经与 TL 线夹角为52.3±5.5~0。此三角区为额肌神经的分布区域。根据本文解剖学观察,经颞额部手术入路的全程切口应避开上述三角区。切口的后端最好在耳屏与耳屏前18.0mm之间入路,此范围不易损伤额肌神经而导致额纹消失。
The frontal branches are derived from the temporal branch of facial nerve.On 35 adult cadavers 62 frontal branches were found.They entered the frontalbelly of occipitofrontalis at about 28.9mm above a line linking the tragus withthe lateral angle of eye(TL line).The angle between the nerve and the TLline was about 52.3 degrees.This triangle area may reflect the distribution ofthe frontal branches and operative incision should not be made in the area.
