摘要
观察６具１１侧成人尸体标本眶下血管、神经分支走行和分布。眶下动脉出眶下孔有一分支与眶下神经分支伴行，经提上唇肌与颧小肌之间分布至鼻唇沟区域皮下，与面动脉、面横动脉的分支吻合构成血管网。该血管分支有三种类型：①与上唇支共干；②直接分支；③与下睑支共干。血省长度平均为１．３ｃｍ，外径约０．１～０．８ｍｍ。从而提出以眶下动脉分支及附带少许皮下组织为蒂轴型皮瓣，应用临床整复鼻面部小面积皮肤软组织缺损７例，效果满意。

course,branch and distribution of the infraorbital arterv and nerve
were observed in thenasolabial region in 6 adult cadavers(3 perfused
with latex).An arterial branch from the infraor-bital artery ,which
is accompanied by a branch from infraorbital nerve,runs downwards
betweenthe eygtomaticus minor muscle and levator labii superior
muscle and spreads subcutaneously inthe nasolabial region. Its
average length is 1. 3 mm with external diameter rangeing from 0.1
to0.8mm.This arterial branch composes the subcutaneous vascular
network with the branches offacial artery and transverse facial
artery,The branch of the infraorbital artery has three types
asfollowing:①common shaft with branch of superior fip;②independent
branch and③commonshaft with branch of lower eyelid. An axial flap
pedicled with the branch of infraorbital artery wascessfully repaired
clinically.
