Blepharoptosis Repair by Small Cutaneous Incision and Minimal Dissection Technique

Purpose: To present a simple method of acquired ptosis correction by small-incision minimal dissection technique and assess the results of the operation. Methods: The charts of 23 patients (29 eyes) with acquired ptosis who underwent ptosis correction by small-incision minimal dissection technique were reviewed. Pre and postoperative MRD1, success rate, complications and reoperation rates were investigated. Results: The average of pre- and postoperative MRD1 were 0.9±0.9 mm and 2.7±0.8 mm respectively. Of the 17 patients who underwent unilateral surgery, 15 eyes (88.2%) showed successful outcomes, and of the 12 eyes who underwent bilateral surgery, 8 eyes (66.6%), 2 eyes (16.7%), and 2 eyes (16.7%) showed excellent, good, and poor outcomes, respectively. Out of 29 eyes, 25 eyes (86.2%) showed satisfactory results. Two eyelids of unsatisfactory contour were corrected by reoperation. Conclusions: Although the small-incision minimal dissection technique for ptosis correction is applicable to a restricted group of patients compared to the conventional method, this technique is very useful and efficient, and has many advantages including less tissue damage, bleeding, edema, a short operation time and rapid recovery.
