摘要
目的:了解支配皱眉肌的神经来源、走行和分布。方法:对13具成人尸体标本共26侧颜面的眶区内、外侧面神经进行大体和显微局部解剖分离,研究支配皱眉肌的神经来源、走行和分布。结果:从眶外侧区走行支配皱眉肌的神经是穿经眼轮匝肌的颞支前、中支吻合网,其入肌区域分布于皱眉肌外侧1/2;在眶内侧区进入眼轮匝肌的神经主要由面神经颧支中下支穿经颧大肌、颧小肌深层向内上进入眼轮匝肌下方深层并行向内眦方向走行,自深面发出分支进入眶区内侧面的降眉间肌、降眉肌,最后自深面进入皱眉肌,其入肌区域分布于皱眉肌内侧即近起点端1/3。结论:支配皱眉肌的神经受皱眉肌内侧及外侧面神经的双重支配,对选择性神经阻断除皱手术在眶内侧区的应用具有指导意义。
Objective To explore the origin,courser and distribution of the facial nerve in the corrugator supercilii region.Methods By micro-isolation and general topographic separation of a total of 26 facial periorbital nerve from 13 fresh cadavers, researching the ori- gin.courser and distribution of the facial nerve in the corrugator supercilii region. Results The dominated nerve of corrugator from the lateral orbital area is the anterior-middle association branch of nervus temporalis, the distribution of.the entrance point is lateral side 1/2 of the corrugator supercilii. The nerves which enter the orbicularis oculi muscle are mainly consist of the united branches include the zygomatic branches of facial nerves that run through deeper part of the major zygomatic muscle up enter the lower part of orbicu- laris oculi muscle toward direction of inner canthus and couple with several secondary facial branches which go through the deeper part of the lesser zygomatic muscle to medial area of periorbital area. Meantime, the latter branch can produce sub-branch to enter the procerus and depressor supercilii of the lateral side in periorbital area and finally enter the corrugator from its deeper part. The entrance points are distribute in the medial side of corrugator, that is one third to the original point. Conclusions Through identifying the characteristics of regional anatomy, we can understand accurately to the fact of the bilateral of the innervation of corrugator su- percilii, which have an important guidance to the application of selective nerve block surgery in removing wrinkle.
