How to determine the amount of levator resection in congenital ptosis repair

Abstract

Background and objective: Levator aponeurosis resection is an effective technique to correct blepharoptosis when the levator function is fair to good. This study aimed to determine the amount of levator resection in congenital blepharoptosis repair. Methods: This is a prospective case series study conducted in Rizgary teaching hospital and private hospitals in Erbil city, Kurdistan Region, Iraq, from June 2011 to August 2019. The data of 53 patients (64 eyelids) affected by congenital blepharoptosis with poor to good levator function that underwent unilateral orbilateral levator resection blepharoptosis repair through the standard approach were included. The final outcome measures included postoperative eyelid height, contour, and symmetry. Results: This study includes a total of 53 patients with congenital blepharoptosis (64 eyelids); 20 males and 33 females. The age of the patients ranged from 3 years to 54 years, with a mean age ± SD of 14.11 ± 10.66 years. The ptosis was right sided in 22 patients (41.5%), left sided in 20 patients (37.7%), and bilateral in 11 patients (20.8%). The study showed good patient satisfaction in 66.03% of the cases, suboptimal satisfaction in 22.64% of the cases, and poor satisfaction in 11.32% of the cases. Conclusion: The levator resection for congenital ptosis is effective even with poor levator function and replaced in our practice the traditional fascial sling. We recommend that further studies be done on a larger number of patients to investigate the effectiveness of levator resection in patients with severe ptosis and very poor levator function.
