目的 :在常规提上睑肌缩短术的基础上 ,研究探讨一种容易暴露寻找提上睑肌的手术方法。方法 :切开上睑皮肤 ,分离部分眼轮匝肌后横行切断睑板中分上方 15 mm宽的结膜前肌肉组织 ,于此肌肉组织两侧纵行向上剪开至眶隔 ,待脂肪外溢后 ,由脂肪溢出处伸入剪刀向另一侧分离 ,并剪断脂肪前组织 ,其后必定是提上睑肌腱膜。结果 :本组 12例 (17眼 ) ,术后效果满意 13眼 ,过矫 2眼 ,矫正不足 2眼。结论 :上睑下垂病人提上睑肌、眶隔发育往往不正常 ,部分病人眶隔位置较高 ,较难寻找和分离。此法便于剪开眶隔和暴露提上睑肌 ,使手术操作变得简单、方便 OBJECTIVE: To study a surgical method that is easy to expose and look for levator muscle. Methods: The upper eyelid skin was incised and the part of the orbicularis oculi muscle was separated by cutting off the part of the orbicularis oculi. The muscle tissue of 15 mm wide before conjunctiva was cut transversely to the orbital septum. , From the fat spill into the scissors to the other side of the separation, and cut off the fat before the organization, then must be levator aponeurosis. Results: The group of 12 cases (17 eyes), postoperative satisfaction with 13 eyes, overcorrection 2 eyes, less than 2 eyes. Conclusion: Patients with ptosis tend to have levator muscle raised. Orbital septum development is often not normal. Some patients have higher orbital septum position and are more difficult to find and separate. This method is easy to cut orbital septum and expose the levator muscle, the surgical operation easier and more convenient
