This literature review aims to provide a comprehensive overview of the current understanding, indications, techniques, outcomes, and complications of Müller muscle-conjunctival resection (MMCR) surgery. It also addresses areas of debate with MMCR such as predictability concerning Phenylephrine response as well as the amount of muscle resection required.
Method
This literature review was compiled based on the available evidence from PubMed from 1975 to August 2023.
Results
The success rate of MMCR ranges from 72% to 95%, with high patient satisfaction reported in most studies. The exact range of eyelid elevation after MMCR is variable, with a reported average of 2.1 mm MRD1 elevation.
Conclusion
MMCR is a well-established surgical technique used to correct upper eyelid ptosis that results from dysfunction or attenuation of the levator aponeurosis. MMCR proved to be a safe and effective procedure with a high patient satisfaction rate and low risk of complications.
