Abstract

PURPOSE: The ideal goal of the surgery for mild or moderate unilateral ptosis is to obtain symmetric palpebral fissure. The purpose of this paper is to evaluate the surgical outcome of mild or moderate unilateral ptosis patients after the procedure of external levator resection.
METHODS
External levator resection with aponeurotic approach was performed on 25 mild to moderate unilateral ptosis patients with less than 2 mm MRD difference from June 1997 through May 2000. Outcome was defined as good, fair, and poor.
RESULTS
Of the patients, 21 patients had congenital ptosis and 4 patients revealed acquired ptosis. Ten patients were male and 15 were female. Age ranged from 3 to 58 years(mean 19.8 years). Amount levator resection was 8~15 mm (mean 11.2 mm) with mild overcorrection. After the follow-up period 6~30 months (mean 10.8 months), 18 patients (72%) showed good results. Three patients (12%) revealed fair, and poor results were noted in 4 patients (16%). Patients with good and fair results were satisfied aesthetic aspect.
CONCLUSIONS
Based on this study, mild overcorrection of levator resection was one of the ideal procedures for mild to moderate unilateral ptosis patients.
