comparative study on conjoint fascial sheath 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.
