本文介绍6例非外伤性单侧上睑退缩畸形,行上睑提肌与Muller氏肌切开松解术整复效果满意。对病例选择,手术方法及注意事项进行简述和讨论。
Six patients with retracted unilateral upper eyelid were operated on by cutting the levator and Muller's muscles under local anesthesia 1% lidocaine was infiltrated into the eyelid and the tissues superficial to the orbicularis oculi muscle. It is important that the infiltration should not enter the deep layer of the muscles to avoid paralysis of the superioris levator palpebra muscle. Incision is made on the upper eyelid about 6mm above the lid margin. The cutting of the levator and Muller's muscles should be limitted to the central portion and leave a strip of muscles intact on both sides. The extent of cutting is decided by adequate correction of lid retraction. With the opposite palpebral fissure as a guide the cutting is extended bilaterally until overcorrection by 1 mm is reached. Adequacy of correction is obtained when the patients can open and close the eyelid. The results in these 6 cases were satisfactory and deformities were corrected.
