An analysis is made of 81 patients with severe blepharoptosis who underwent correction with autogenous fascia. In case of severe blepharoptosis, which means a levator function of less than 5 mm, correction by levator resection gives insufficient results. Better results are obtained by frontalis suspension, whereby the upper eyelid is connected to the frontalis muscle using fascia lata strips according to Crawford. The operative technique is described in detail. Particular interest has been paid to the width of the vertical lid fissure and symmetry between both upper eyelids after operation. The overall results were rated satisfactory to excellent with an average of 9 mm of postoperative vertical lid fissure. Comparison of the results of unilateral versus bilateral blepharoptosis correction revealed better results in the group of bilateral ptosis correction. In 76% of the bilateral patients, there was an asymmetry of less than 0.5 mm between both palpebral fissures, while in the unilateral group this result was achieved in only 35% of the cases. Symmetry is difficult to achieve in the unilateral group, especially when the vertical lid fissure of the nonptotic eye is 10 mm or more. In these cases, correction of both upper eyelids should be considered. The best time to operate on patients with severe congenital blepharoptosis is around the age of 4 to 5 years, because lagophthalmus after operation is better tolerated and the leg has developed sufficiently to provide an adequate amount of fascia. The correction of severe blepharoptosis by frontalis suspension with autogenous fascia shows a high rate of success and few complications.
对81例接受自体筋膜矫正重度上睑下垂的患者进行了分析。对于重度上睑下垂,即提上睑肌功能小于5mm的情况,提上睑肌切除术矫正效果不佳。采用额肌悬吊术可获得更好的效果,根据克劳福德的方法,使用阔筋膜条将上睑与额肌相连。详细描述了手术技术。特别关注术后垂直睑裂的宽度和双侧上睑之间的对称性。总体结果评定为满意至优秀,术后垂直睑裂平均为9mm。单侧与双侧上睑下垂矫正结果的比较显示,双侧上睑下垂矫正组效果更好。在76%的双侧患者中,双侧睑裂之间的不对称小于0.5mm,而在单侧组中,只有35%的病例达到了这一结果。在单侧组中很难实现对称性,尤其是当健眼的垂直睑裂为10mm或更大时。在这些情况下,应考虑矫正双侧上睑。重度先天性上睑下垂患者的最佳手术时间约为4至5岁,因为术后兔眼更容易耐受,且腿部已充分发育,足以提供足够的筋膜。采用自体筋膜额肌悬吊术矫正重度上睑下垂成功率高,并发症少。
