    Abstract:
    To conduct a study on ptotic eyelids with Marcus Gunn jaw-winking ptosis operated via a technique of modified levator plication, prospective interventional case series. Ten ptotic eyelids with Marcus Gunn jaw-winking phenomenon (MGJWP) underwent modified levator plication surgery. Postoperatively, all cases were followed up for at least 6 months. Outcome parameters included amount of ptosis correction, amount of MGJWP correction, palpebral aperture height, lid lag, and lagophthalmos. The mean amount of ptosis was 4.25 ± 0.79 mm (range of 3-6 mm), mean amount of MGJWP was 5.10 ± 2.27 mm (range 2-9 mm), and the mean levator function was 8.3 ± 2.27 mm (range of 4-12 mm). At 6 months follow-up, good correction of ptosis was seen in nine out of ten patients. Resolution of MGJWP (≤1 mm of excursion of upper eyelid with synkinetic mouth movement) was seen in three patients. Improvement in MGJWP (>1 mm of excursion of upper eyelid with synkinetic mouth movement) was seen in seven patients. The mean post-operative lagophthalmos was 0.80 ± 0.88 mm. The modified levator plication technique was effective in the treatment of MGJWP. This modified technique of levator plication is anatomically less destructive and hence more acceptable, with the added advantages of less post-operative lagophthalmos and no lid contour defects.
