The significance of minimal adjustments in the Muller's muscle and conjunctiva resection procedure to achieve the phenylephrine result.

PURPOSE: To determine if adjusting the resection amount within a small range has a significant effect in the amount of lift achieved when performing the Muller's muscle and conjunctiva resection procedure (MMCR). METHODS: A retrospective chart review was performed analyzing 102 eyelids of 68 patients with involutional blepharoptosis that had a MMCR resection amount ranging from 8.0-9.5 mm performed by a single surgeon (P.S.) RESULTS: The average lift for all resections was 2.30 mm. When comparing amongst all resection groups, there was no significant difference in the amount of lift obtained (p = 0.2454). CONCLUSION: When performing the MMCR procedure, adjusting the resection amount within a small range of 8.0-9.5 mm does not affect the amount of lift achieved.
