Ocular exposure, conjunctival irritation and corneal keratitis are disturbing consequences of facial paralysis with lagophthalmos. Many techniques have been described for correcting this condition. A new method for decreasing the palpebral fissure is presented. An ear cartilage graft is interposed between the tarsal plate and the levator palpebrae superioris muscle. 12 patients with paralysis of the orbicularis oculi muscle, as assessed by electromyography, were treated with this technique. The palpebral fissure was decreased by 2-3 mm in all cases. 11 patients showed significant improvement of their eye symptoms. One patient, in whom the palpebral fissure could not be closed sufficiently to protect the eye, required additional lengthening by 4 mm of the cartilage graft and a lateral tarsorrhaphy.
眼球暴露、结膜刺激和角膜角膜炎是面瘫伴眼睑闭合不全令人困扰的后果。已经描述了许多纠正这种情况的技术。本文介绍了一种减小睑裂的新方法。将一块耳软骨移植片置于睑板和提上睑肌之间。通过肌电图评估，12例眼轮匝肌麻痹患者接受了该技术治疗。所有病例的睑裂均减小了2 - 3毫米。11例患者的眼部症状有显著改善。1例患者的睑裂无法充分闭合以保护眼睛，需要将软骨移植片再延长4毫米并进行外侧睑缘缝合术。
