Purpose: To compare the outcomes of blepharoptosis repair using conjunctival Müllerectomy with or without tarsectomy (CM±T) using absorbable suture versus nonabsorbable suture.
Methods: Retrospective case-series of all consecutive cases of CM±T ptosis repair between January 1, 2019, and August 31, 2021. Patients were placed in groups based on whether they had absorbable or nonabsorbable suture used during their procedure. Preoperative and postoperative measurements of MRD1 were gathered in both groups, and information on patient satisfaction, symmetry, complications, and reoperations.
Results: Ninety-two patients had surgery using nonabsorbable suture and 96 patients had surgery using absorbable suture, with average age of 72.0 and 70.9 years, respectively ( p = 0.488). When comparing nonabsorbable to absorbable suture, the groups did not differ on average preoperative MRD1 (1.11 mm [±0.96] vs. 0.96 mm [±0.86]; p = 0.161), average postoperative MRD1 (3.18 mm [±0.54] vs. 3.20 mm (±0.51); p = 0.736) or average MRD1 improvement (2.09 mm (±0.86) vs. 2.25 mm (±0.79); p = 0.089). Goal MRD1 was achieved in 85.3% of nonabsorbable cases and 82.8% of absorbable cases ( p = 0.562) and the rate of reoperation between groups was not significant ( p = 0.63). Good postoperative symmetry was noted in 91.6% of nonabsorbable and 91.0% absorbable suture cases ( p = 0.83). No difference in the number of complications was noted between groups ( p = 0.88), including need for contact lens placement (2.7% nonabsorbable, 1.3% absorbable; p = 0.37).
Conclusions: The use of absorbable suture was found to have predictable and effective outcomes similar to cases using nonabsorbable suture for CM±T without an increase in complications or rate or reoperation.
