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。 Observe the infraorbital vessels and the branches and distributions of nerve branches in 6 11 adult cadaveric specimens. The infraorbital artery has a branch out of the infraorbital foramen and a branch of the infraorbital nerve, which is distributed subcutaneously to the nasolabial fold region between the supraspinatus and zygomaticus muscle, and anastomosed to the branches of the facial artery and facial transverse artery. The vascular branch has three types: ① with the upper lip branch dry; ② direct branch; ③ and the lower eyelid branch were dry. Blood provincial average length of 1.3cm, diameter of about 0.1 ~ 0.8mm. In order to put forward the infraorbital artery branches and attached to a small amount of subcutaneous tissue pedicle-based pedicle flap, the application of clinical rehabilitation of nasal small area skin and soft tissue defects in 7 cases, the effect is satisfactory.
