Abstract
- The best results of ptosis surgery will be obtained by properly evaluating the types of ptosis, the degree of levator function, and the amount of ptosis. The authors reviewed 55 patients(79 eyes) of congenital blepharoptosis who received external levator resection and frontalis sling. The following results were obtained. 1. Simple ptosis cases were 85.5%, ptosis with other lid anomalies were 3.7%, ptosis with ophthalmoplegias were 9%, and synkinetic ptoses were 1.8%. 2. Mild ptosis(1.5 to 2 mm) cases were 0%, moderate ptosis(3 mm) cases were 5%, and severe ptosis(4 mm or more) cases were 95%. 3. 78.5% of congenital ptosis cases were poor levator function(4 mm or less), 19% were fair levator function(5 to 7 mm), and 2.5% were good levator function(8 mm or more). 4. Good results were obtained in 80% of the external levator resection cases. 5. Even when there was poor levator function(3 to 4 mm), a large levator resection(22 to 24 mm) was a good primary procedure.
