PURPOSE: Müller muscle-conjunctival resection (MMCR) is a popular posterior/internal surgical approach to cases of mild to moderate blepharoptosis with good levator function. MMCR necessitates the removal of healthy conjunctiva and exposes the cornea to suture material. The goal of this study is to describe a novel sutureless conjunctiva-sparing Müllerectomy (CSM) surgery and demonstrate its long-term efficacy, efficiency, and safety.
DESIGN: IRB approved retrospective study of patients undergoing sutureless conjunctiva-sparing posterior ptosis repair surgery.
METHODS: The medical records of 100 patients (171 eyes) who underwent sutureless CSM with a minimum follow-up interval of 6 months were retrospectively reviewed. Photographs were analyzed using ImageJ software. Outcome measures were derived from margin reflex distance 1 (MRD1) and palpebral fissure height (PFH) at various postoperative timepoints.
RESULTS: Mean ΔMRD1 and ΔPFH at 6 months were 2.85 ± 0.98 mm and 2.60 ± 1.38 mm, respectively. Symmetry within 1 mm was observed 91% of cases. Sutureless CSM took 4.42 minutes on average compared to 8.45 minutes for traditional MMCR. There were no corneal abrasions or ocular complications. The reoperation rate was 2.3% (1 case of overcorrection and 3 cases of undercorrection) per eye.
CONCLUSIONS: Sutureless CSM is a promising alternative to traditional MMCR and sutured CSM based on long-term outcomes, symmetry, shorter operative time, and low complication rate. NOTE: Publication of this article is sponsored by the American Ophthalmological Society.
