Purpose: The purpose of this study was to compare the efficacy of Müller muscle-conjunctival resection (MMCR) with or without suturing for the correction of ptosis.
Methods: A retrospective chart review was performed of 30 patients (56 eyelids) undergoing sutureless (sMMCR) (34 eyelids) or conventional MMCR (cMMCR) (22 eyelids). Primary outcome measures were the change in MRD1 and vertical eyelid height (VLH). Secondary outcome measures were the amount of resection of MMCR (rMMCR) and postoperative symmetry of 1 mm or less.
Results: In total, 49 eyelids (87.5%) had involutional ptosis and 7 (12.5%) had contactlens induced ptosis. The age and follow up between the sMMCR and cMMCR groups was, respectively, 65.1 ± 11.0 versus 65.5 ± 11.0 years and 4.0 ± 2.5 versus 6.5 ± 2.1 months. Preoperatively there were no significant differences noted between the sMMCR and cMMCR groups. Postoperatively there was a statistically significant difference in change of MRD1 between the sMMCR and cMMCR groups, 2.74 ± 0.20 mm and 2.02 ± 0.25 mm ( p = 0.026). The difference in change of VLH and rMMCR was not significant between the sMMCR and cMMCR groups, 2.28 ± 0.13 mm and 2.14 ± 0.15 mm ( p = 0.49) and 9.29 ± 2.14 versus 9.46 ± 1.97 mm ( p = 0.83). There were no significant differences in postoperative symmetry.
Conclusion: The sMMCR and cMMCR techniques demonstrated equal effectiveness for the correction of ptosis. The rapid sMMCR could become the procedure of choice for the correction of involutional and contact lens induced ptosis.
