摘要
面神经瘫痪将导致受其支配的眼轮匝肌麻痹，而使该肌所司闭眼功能丧失，但该肌的拮抗肌提上睑肌和米勒氏肌的功能存在并相对亢进，因而造成患者睁眼时睑裂过大畸形、闭眼时兔眼畸形。作者在局麻下由结膜入路，距睑板上缘２ｍｍ处切断睑板上缘中部的提上睑肌和米勒氏肌，直至术中睁睑时双侧睑裂宽度大致相同为止。术后患者睁眼时双侧睑裂宽度大致相同，闭眼时兔眼畸形也有所改善，疗效满意。
Orbicular muscle of eye is paralyged in facial palsy, and it's function of palpebral closing is lost. while levator and Mller's muscle, the antagonistic muscles of orbicular muscle, are working well and their function are relatively accentuatied. Therefore, hypereuryopia with palpebral opening and lagophthalmus with palpebral closing will happen. Partial levator and Mller's muscle excision 2mm above the medial portion of superior margin of tarsus is carried out through conjunctiva incision under local anaesthesia. It treats hypereuryopia satisfactorily and also improves lagophthalmus.
