New approach in Muller’s muscle-conjunctival resection

Author: Elena Goltsman
ePoster Number: 102


Purpose

Proposed a new technique for Muller’s muscle-conjunctival resection (MMCR), which can be used in patients with different responses to phenylephrine (PE) test and compare results with standard «open sky» MMCR.


Methods

In this study were included 2 groups of patients with mild and moderate blepharoptosis and levator muscle function 8 mm or more. The main group (75 patients,103 eyelids) was performed a modified MMCR, and patients of comparison group (26 patients, 35 eyelids) underwent an “open sky” MMCR. MMCR in the main group was planned according to the following algorithm, proposed by the authors. In cases with positive and sufficient PE test, 2/3 of the Muller’s muscle (MM) was resected. In case of positive and insufficient PE test (when PE test is positive, but doesn’t completely eliminate blepharoptosis), subtotal MM resection was performed. In case of negative or weakly positive PE test, an assessment of the white line mobility (WLM) was additionally performed intraoperatively. If WLM (in mm) was equal to the amount of ptosis, subtotal MM resection was performed. If WLM was less than desired amount of correction, then subtotal MM resection was combined with tarsal plate resection.


Results

The evaluation parameters were degree of ptosis, the result, the width of the palpebral fissure in the center, lateral and medial limbus, MRD 1 and MRD 2. All parameters didn’t significantly differ between the groups (p > 0,05). But the frequency of hypo- and hypercorrections was significantly higher in the control group (p < 0,05).


Conclusion

New algorithm of modified MMCR allow to correct blepharoptosis using transconjuctival methods in cases of weakly positive and negative PE test and also to reduce hypo- and hypercorrection frequency.
