Abstract

Background: To evaluate the clinical efficacy of combined minimal lower eyelid epicanthoplasty and thermal contraction for epiblepharon repair in Chinese children.

Methods: Between January 2017 and August 2020, a single surgeon corrected epiblepharon in Chinese children using minimal lower eyelid epicanthoplasty combined with thermal contraction. First, a minimal epicanthoplasty flap to balance the lower eyelid was made cross the lower eyelid epicanthus, which connected with a 20-mm-long incision 1.5 mm below the lower eyelid margin. After removing the hypertrophic orbicularis oculi muscle running between the lower epicanthal fold and the medial canthal tendon, thermal cauterization was applied to increase lower eyelid rotation by creating adhesions between the lower eyelid retractor and tarsus. The residual medial edge was sutured to the corner of the epicanthus to decrease the lower eyelid epicanthus. The postoperative follow-up ranged from 3 to 24 months. We retrospectively analyzed cases to determine whether this approach decreased the lower eyelid epicanthal fold to equalize the tension of the lower eyelid. The surgical outcomes including the direction of lower eyelid eyelashes, complications, and refractive errors were evaluated.

Results: Data from each eye of 53 Chinese children (29 female, 24 males; mean age: 5.3 ± 2.3 years) who had undergone minimal lower eyelid epicanthoplasty combined with thermal contraction were included. During follow-up, recurrence was observed in just one of the 106 eyes (0.94%), and two eyes (1.89%) showed under-correction. No visible scars formed in the postoperative period. All patients' parents were satisfied with the cosmetic results and had no serious complaints. The mean astigmatism was significantly reduced by the surgery from 1.82 ± 0.45 diopters (D) preoperatively to 1.43 ± 0.36 D postoperatively (P < 0.05).

Conclusion: This surgery is easy to design, time-efficient, and is effective in the correction of epiblepharon. The procedure allows surgeons to achieve good appearance and natural eyelid contour without apparent complications.
