Abstract

PURPOSE

Surgical treatment of myogenic ptosis usually requires a form of frontalis suspension. Complications can include entropion, headache, contour abnormalities, and poor eyelid excursion. The Levine palpebral spring has been used successfully to augment eyelid closure in more than 2,000 patients. The authors present a modified Levine spring to correct ptosis in a patient with poor levator function.

METHODS

Interventional case report. A 55-year-old man with profound myogenic ptosis was treated with bilateral modified Levine palpebral springs. Eyelid position, contour and excursion, blink reflex, lagophthalmos, and ocular surface were evaluated.

RESULTS

The Levine palpebral spring functioned well to open both eyelids. Margin reflex distance improved from -3 mm to 3 m postoperatively. Excellent contour and excursion were observed. Orbicularis action, including blink reflex, was preserved, and ocular surface was not compromised.

CONCLUSION

The modified Levine palpebral spring is an alternative to frontalis suspension in treating select patients with eyelid ptosis with poor levator function.

摘要

目的

肌源性上睑下垂的手术治疗通常需要进行额肌悬吊术。并发症包括睑内翻、头痛、轮廓异常和眼睑运动不良。Levine 睑板弹簧已成功用于增强 2000 多例患者的眼睑闭合。作者介绍了一种改良的 Levine 弹簧,用于矫正提上睑肌功能不良患者的上睑下垂。

方法

介入性病例报告。一名 55 岁的男性,患有严重的肌源性上睑下垂,接受了双侧改良的 Levine 睑板弹簧治疗。评估了眼睑位置、轮廓和运动、眨眼反射、睑裂闭合不全和眼表面。

结果

Levine 睑板弹簧能很好地打开双眼睑。术后,边缘反射距离从-3mm 改善至 3mm。观察到良好的轮廓和运动。眼轮匝肌功能(包括眨眼反射)得以保留,眼表面不受影响。

结论

改良的 Levine 睑板弹簧是治疗提上睑肌功能不良的眼睑下垂患者的额肌悬吊术的替代方法。
