External Levator Advancement vs Müller’s Muscle–Conjunctival Resection for Correction of Upper Eyelid Involutional Ptosis

摘要: Purpose To compare external levator advancement and Muller's muscle–conjunctival resection (conjunctivomullerectomy, or CJM) for correction of upper eyelid involutional ptosis. Design Retrospective, nonrandomized, comparative interventional case series. Methods Review medical records 159 patients (272 surgical procedures) who underwent CJM was performed. main outcome measures: Functional cosmetic outcome, marginal reflex distance one (MRD1), complications. Results A total (51 men, 108 women, mean age 70 years) 272 procedures ptosis; concurrent blepharoplasty performed in 141 cases. MRD1 increased an average 1.6 (±1.5) mm, from 0.8 mm (±1.2) preoperatively to 2.3 postoperatively ( P Conclusions External alone with are effective treatments Residual ptosis postoperative retraction occurs up 20% cases can be addressed successfully a second operation.
