RESUMO
BACKGROUND: Blepharoptosis is a common and challenging clinical problem for oculoplastic surgeons, and various surgical techniques have been used to correct ptosis. The aims of this study were to present the clinical results of a modified technique using levator aponeurosis-Müller muscle-reinforced plication for blepharoptosis correction and to demonstrate its advantages over conventional advancement or plication methods. METHODS: This study was conducted in the Plastic Surgery Department of Sir Run Run Shaw Hospital between April 2017 and September 2018. By using this modified technique, the levator-Müller complex was reinforced with a plication suture that pierced under and through the levator-Müller complex, and the posterior and lower part of the levator-Müller complex was advanced to the tarsus, which provided permanent, reliable adhesion. The primary outcome was marginal reflex distance 1 preoperatively and postoperatively. Secondary outcomes were the cosmetic outcome, complications, and operative time. RESULTS: Eighty-six patients (169 eyelids) underwent this modified surgery. Patients' average age was 26 ± 7.6 years, and the median follow-up was 14 months. The preoperative and postoperative mean marginal reflex distance 1 values were 1.72 ± 0.32 and 3.69 ± 0.28 mm, respectively. The amount of plication ranged from 4 to 15 mm. The overall surgical success rate was 88.17%. Some complications were observed including undercorrection (5.92%), asymmetry (4.73%), lagophthalmos (0.59%), and conjunctival prolapse (0.59%). CONCLUSIONS: The modified technique provided good functional and cosmetic outcomes for blepharoptosis correction by avoiding unpredicted adhesion, and it has its advantages including simplicity, easy adjustment of the eyelid height intraoperatively, minimal edema formation, and high success rate.
