目的：对比联合筋膜鞘(conjoint fascial sheath，CFS)悬吊术与上睑提肌缩短术在治疗先天性中重度上睑下垂方面的疗效差异。
方法：收集符合条件的上睑下垂患者43例74眼，随机分配进行CFS悬吊术或提上睑肌缩短前徙术，随访观察6mo，通过统计学检验分析两种术式的正矫率及并发症。
结果：两种术式治疗中度上睑下垂疗效相比无统计学差异(P>0.05)。而CFS悬吊术治疗重度上睑下垂的正矫率高于提上睑肌缩短术(P<0.05)，并且CFS悬吊术具有更少的并发症。
结论：CFS悬吊术在矫正先天性重度上睑下垂时较提上睑肌缩短术有更高的正矫率，同时还具有创伤小、可重复性强、并发症少等优点。

AIM:To compare the curative effect of conjoint fascial sheath(CSF)suspension and levator muscle resection for moderate or severe congenital ptosis.
METHODS: Forty-three patients(74 eyes)with moderate or severe ptosis were treated by CSF suspension or levator muscle resection randomly, and followed up for 6mo. The normalization rates of the two operations were then compared by statistical method, and the complications of the two operations were analyzed.
RESULTS: The two operations appeared no significant difference on the normalization rate for moderate congenital ptosis(P>0.05), while the normalization rate of CSF suspension on severe congenital ptosis was significantly higher than that of levator muscle resection(P<0.05). Less complication was happened in the CSF suspension group than in the levator muscle resection group.
CONCLUSION: CSF suspension is more effective on the treatment of severe congenital ptosis than levator muscle resection, and has advantages such as less trauma, repeatable, and less complication.
