Transconjunctival Müller's muscle Tucking Method for Non-incisional Correction of Mild Ptosis: The Effectiveness and Maintenance.

Abstract

In patients with a mild degree ptosis who undergo non-incisional double-eyelid blepharoplasty, simultaneous correction of ptosis is needed to prevent loosening. The transconjunctival Müller's muscle tucking (TMMT) method may be useful in these cases. The authors performed this study to present the details of the current use of the TMMT method and to provide objective evidence for ptosis correction and its sustained effect. A total of 322 eyelids in 161 patients who underwent mild ptosis correction with the TMMT method from July 2012 to December 2017 were retrospectively examined. The continuous suture method using a single stitch was used for double-fold formation, and the TMMT method was used for ptosis correction for the other incision. The margin to reflex distance (MRD) 1 was evaluated at pre-operation, immediate post-operation, and at 2, 6 months post-operation. A total of 34 patients who had more than 6months of follow-up were included. Right-side MRD1 values were 2.08 (± 0.19) mm before the surgery, 3.49 (± 0.16) mm immediately after the surgery, 3.33 (± 0.14) mm at postoperative 2months, and 3.22 (± 0.17) mm at postoperative 6months (p < 0.001). The difference of MRD1 between immediate post-operation and at 6months was 0.25mm without statistical significance (p > 0.05). Complications (fold loosening, asymmetry, and ptosis recurrence) occurred in three cases (8.8%), all of which were re-corrected by applying the TMMT method. The TMMT method was useful for correction of mild ptosis, showed little recurrence, and prevented loss of fold by giving a vertical force to the double-fold.
