摘要
本文通过２０具尸体额肌解剖发现，额肌行走到眼轮匝肌深面时分为深浅两部分，浅部肌纤维较多与皱眉肌、眼轮匝肌相交织，深部延续为厚约０．２～１．１ｍｍ，平均０．５６ｍｍ的致密膜状组织，下续于眶隔。根据此解剖特点，我们改良了传统额肌瓣术式，在治疗重度上睑下垂中获得了良好的效果，本文还介绍了用不同额肌瓣术式治疗４１例重度上睑下垂之体会。
Abstract According to the anatomy of 20 side corpse's frontalis muscles, the authors found that frontalis muscle divided into two parts under the orbicu laris oculi muscle:superficialis part and profundus part. The superficialis part has more muscular fibers and mixes closely with orbicularis oculi muscular fibers and superciliary mulscular fibers.The profundus part becomes a aponeurosis-like laminal tissue and connects with orbital septum with the thickness range 0.2 ～1.1mm, average of 0.56mm.According to the anatomic characteristic of frontalis muscle.authors reformed the frontalis muscle flap suspension operation and achieved satisfactory clinical effect in treatment of severe blepharoptosis of upper lid.The authors introduced the experiences in treatment of 41 cases blepharoptosis of upper lid with different frontalis muscle flaps.
