Role of Orbicular Oculi Muscle Resection in Double Eyelid Surgery to Correct Ptosis of Young Adults: A Retrospective Review in 121 Chinese Patients.

BACKGROUND

A plump single eyelid with ptosis is the morphological feature of Asians. Orbicularis oculi muscle (OOM) technique can correct ptosis and get a good appearance.

METHODS

A retrospective study was conducted in 121 Chinese patients who underwent double eyelid surgery with medial epicanthoplasty using OOM resection technique from December 2016 to December 2019. Preoperatively, all the patients had good or excellent levator function while skin fold overlapping the upper eyelid margin was found. Palpebral fissure height, upper eyelid margin reflex distance, complications, and cosmetic results were evaluated. Comparisons were performed preoperatively and postoperatively.

RESULTS

The study included 121 patients. Mean follow-up time was 12.8 months (range, 6-32 months). Mean margin reflex distance increased from 1.96 ± 0.60 mm preoperatively to 3.74 ± 0.50 mm postoperatively (P < 0.001), mean palpebral fissure height increased from 6.31 ± 0.51 mm preoperatively to 8.33 ± 0.52 mm postoperatively (P < 0.001). Most patients obtained satisfactory results. Only 1 patient was under correction, 2 patients were with mild asymmetry 6 months postoperatively.

CONCLUSIONS

Ptosis of the upper eyelid can be corrected by the OOM resection technique without any procedure on levator muscle. This technique can be an alternative method for the correction of ptosis of the upper eyelid.
