# The change in quality of life after Muller's muscle-conjunctival resection surgery for eyelid ptosis repair

## TL;DR

This study shows that Muller's muscle-conjunctival resection surgery improves quality of life for eyelid ptosis patients in the long term.

## Contribution

The study provides long-term evidence of quality of life improvement after MMCR surgery for eyelid ptosis.

## Key findings

- The mean MRD1 increased significantly from 1.65 mm pre-surgery to 3.2 mm post-surgery.
- Patients reported a mean GBI score of 57.48, indicating substantial benefit from the surgery.
- Good patient selection based on pre-operative characteristics leads to high satisfaction rates.

## Abstract

To evaluate the long-term effect of the Muller's Muscle-Conjunctival Resection (MMCR) procedure on patient's quality of life.

This retrospective study included patients that underwent MMCR surgery for eyelid ptosis repair at our institution between the years 2016–2018 and had at least 3 months postoperative follow up. All patients completed the 18-questions post-interventional, validated, Glasgow Benefit Inventory (GBI) questionnaire via telephone interview.

50 patients were included in the study group. The mean MRD1 measurement before ptosis repair surgery was 1.65 mm (± 0.82), with significantly higher MRD1 after a long post-operatively period, of 3.2 mm (± 1.03) (Matched pairs, p < 0.001). The mean total GBI score was 57.48 (± 4.72) out of 90, after an average follow up period of 712 days.

The MMCR eyelid ptosis repair surgery has a positive, long-term effect on patient’s quality of life. Good patient selection for specific type of ptosis surgery, based on pre-operative clinical characteristics, can result good outcome with high satisfaction rates.
