眼轮匝肌蒂颞区皮瓣解剖学研究

Applied anatomic study on the temporal flap pedicled with orbicularis oculi muscle

目的 探讨眼轮匝肌蒂颞区皮瓣的解剖学基础。方法 对 15具成人尸体的 30侧头面部进行解剖 ,对 15例活体行颈总动脉数字减影血管造影 (DSA) ,并观察颞浅动脉分支与眼轮匝肌营养血管的关系 ,将所得信息用计算机进行图像分析。结果 眼轮匝肌有多条血管在眼睑内形成动脉网 ,此动脉网与供应颞区皮肤的颞浅动脉分支 :额支和颧眶动脉相吻合 ,且颧眶动脉位置较恒定 ,口径平均在 1.0mm以上。结论 颧眶动脉是眼轮匝肌蒂颞区皮瓣的主要营养血管 。

Objective To investigate the anatomic basis of the temporal flap pedicled with the orbicularis oculi muscle. Methods The morphology and the blood supply of the orbicularis oculi muscle were studied on 15 cadavers by surgical dissection and vascular cast.Using digital subtraction angiography (DSA),we observed the branches of the superficial temporal artery in 15 patients.The data was then analysed by the computed image analysis system. Results The orbicularis oculi muscle was wide and thin and located superficially.It was supplied by the branches of many arteries and the branches have numerous connections with the branches of superficial temporal artery.The position of the zygomaticoorbital artery was unvaried .The diameter of the artery was up to 1.0 mm. Conclusion Zygomaticoorbital artery is the most important vessel for the temporal flap pedicled with the orbicularis oculi muscle.
