眼轮匝肌蒂皮瓣修复眼睑及睑周组织缺损的解剖学基础

Anatomical Basis of the Skin Flap pedicled with the Orbicularis Oculi Muscle

目的为眼轮匝肌蒂皮瓣修复眼睑及睑周组织缺损提供解剖学依据。方法对15具成人尸体的(30侧)头面部进行解剖,观测眼轮匝肌的形态和血供。结果眼轮匝肌血供来自面动脉系统和眶动脉系统的分支,这些动脉在眼睑形成动脉网,为以眼轮匝肌为蒂的肌皮瓣提供血供保障。结论眼轮匝肌蒂皮瓣可以用来修复眼睑及睑周组织缺损。

Objective To provide anatomical basis of the skin flap pedicled with the orbicularis oculi muscle to repair the eyelid tissue defects or the margin tissue defects of the eyelid. Methods 15 adult cadavers （30 eyelids） were dissected step by step. The configuration and the blood supply of the orbicularis oculi muscle were observed. Results The blood supply of orbicularis oculi muscle origins from the branches of the facial artery and the orbital artery, These arteries form widespread and constant vascular network to supply the skin flap pedicled with the orbicularis oculi muscle. Conclusions The skin flap pedicled with the orbicularis oculi muscle can be used to repair the eyelid tissue defects or the margin tissue of the eyelid.
