Management of Marcus Gunn jaw wink syndrome with tarsofrontalis sling vis a vis levator excision and frontalis sling: a comparative study.

Purpose: To compare the results between tarsofrontalis sling (TFS) and levator palpebrae superioris (LPS) excision with TFS in cases of ptosis with Marcus Gunn jaw winking syndrome (MGJWS).
Method: A retrospective review of records of all patients undergoing either TFS (group A) or LPS excision along with TFS (group B) in cases of ptosis with MGJWS was done over the past 10 years and their results were compared.
Results: The study included 73 patients (75 eyes). There were 36 patients (36 eyes) in group A and 37 patients (39 eyes) in group B. There was a significant reduction in the excursion due to MGJWS from 4.7 ± 1.49 to 1.91 ± 1.04 mm in group A (p = .001) and 4.65 ± 1.34 to 1.79 ± 0.98 mm in group B (p < .05). The reduction in excursion due to MGJWS and lagophthalmos were comparable in both groups. The mean follow-up in group A was 5.62 ± 6.94 (Range: 1-24) months and group B was 19.15 ± 29.16 (Range: 1-96) months (p = .01).
Conclusion: Both TFS and LPS excision with TFS is equally effective in dampening the eyelid excursion in MGJWS. Tarsofrontalis sling is a safe, easy and effective technique for MGJWS with lesser complication.
