The Outcome and the Influential Factors Involved in Levator Resection for Blepharoptosis Correction

Purpose: to identify any factors that may predict successful levator resection in blepharoptosis correctionmethods: the hospital records of 52 consecutive patients undergoing anterior levator resection for unilateral congenital blepharoptosis were reviewed. successful result was defined a lid level within 1 mm of the fellow eye 1 year after surgery. we studied the effect of levator function, the amount of ptosis and the kind of anesthesia on the surgical outcome.results: twenty-eight patients (53.8%) were treated with a levator resection under local anesthesia (group 1) and 24 patients (46.2%) were treated with a levator resection under general anesthesia (group 2). the mean age was 16.37±9.3 (range 4-40) years. the overall success rate was 76.9% two months after surgery and 61.5% one year after surgery. the most common complication after one year was undercorrection (38.5%). sever ptosis (p=0.002) and decreasing preoperative levator function (p=0.007) were associated with decreasing chance of success. the kind of anesthesia was not a predictor factor for surgical success (p=0.312).conclusion: the preoperative levator function and the amount of ptosis were found to be the most significant predictors of surgical outcome. the surgery under local anesthesia was not associated with a higher success rate.
