上睑提肌内限制韧带松解在治疗先天性上睑下垂中的意义

目的 在睑板上缘附近的上睑提肌内，有跨于内外眦角之间数条横向纤维束带即限制韧带，我们探讨其在治疗先天性上睑下垂中的意义。方法 将此韧带松解，可基本矫正大部分经度上睑下垂病例。若为轻，中度上睑下垂，且韧带松解后上睑仍有部分下垂，还需进行睑提肌腱膜折叠术。重度上睑下垂韧带松解后，还需进行眉区额肌筋膜瓣悬吊术。结果 本组27例随访3个月～1年，27例40只眼中38只眼轻、中、重度上睑下垂均矫正满意，2只眼良好，未见睑下垂复发。结论 松解上睑提肌内限制韧带，有助于恢复上睑提肌睑功能，易于矫正睑下垂且手术创伤小，形态自然，不易复发。

The role of releasing the fibrous bundles across levator muscle in correcting congenital blepharoptosis

Objective To investigate the role of releasing the fibrous bundles across the levator muscle between the medial canthus and lateral canthsus near the top of tarsus in the correction of the congenital blepharoptosis. Methods Twenty-seven patients with 40 eyes of blepharoptosis were undergoing the treatment. It was performed by releasing the fibrous bundles across the levator muscle between the medial canthus and lateral canthsus near the top of tarsus to correct the mild and moderate blepharoptosis. A further procedure can also be added to by folding the levator aponeurosis if necessary. In the severe blepharoptosis, the frontalis aponeurose flap may be applied for the suspension as well during the operation. Results Of the 40 eyes in 27 cases with mild,moderate and severe blepharoptosis were treated by using this method, with 38 eyes corrected satisfactorily and 2 eyes corrected mostly in the following-ups from 3 months to 1 year. Conclusion The above mentioned technique may be a good, simple and effect method to corret congenital blepharoptosis.;
