Surgical Correction for Pediatric Epiblepharon and Trichiasis
July 8th, 2025
Here, we present a protocol for surgical correction for pediatric epiblepharon and trichiasis.
We studied the surgical correction effect of lower eyelid epiblepharon and trichiasis. We follow up with the patient to study detailed surgical outcomes and the prognosis of patients. In this study, the vision suture method is combined with surgery, which has been found to reduce the recurrence rate.
In addition to excising the redundant skin in the orbicularis oculi muscle, the epiblepharon correction procedure adopted fixes the orbicularis oculi muscle from the upper lip of the incision to the tarsus, increasing the adhesion between the anterior and the posterior layers of the eyelid, and changing the eyelashes afterwards. To begin, use a high-frequency electric knife to incise the skin along the pre-designed incision line, and extend the incision to the superficial layer of the orbicularis oculi muscle. Excise the pre-designed crescent-shaped or L-shaped lower eyelid skin along the incision line, together with the superficial layer of the orbicularis oculi muscle.
Then, dissect the incision margin into the lower margin of the lower tarsus using a bipolar electrotome, taking care to avoid damaging adjacent structures and nerves. Using bipolar coagulation, ensure the surgical field is free from active bleeding points, to prevent postoperative hematoma and subcutaneous ecchymosis. To begin internal fixation and suture, use a 6-0 absorbable suture to place an eight-shaped stitch, incorporating the preaponeurotic fascia of the lower eyelid retractor, and the subcutaneous tissue adjacent to the upper margin of the incision.
Adjust the knot tightness to restore the eyelashes to a normal position. Apply stitches with consistent spacing and appropriate tension to promote favorable wound healing. Now, observe the lower eyelid margin for slight downward displacement.
Then excise any excess skin along the projection line of the upper incision following internal fixation, ensuring the remaining skin below the incision lies completely flat. Close the skin incision using a 7-0 non-absorbable polypropylene suture, ensuring neither the tarsus nor the lower eyelid retractors are incorporated to avoid double-eyelid plasty. Align the sutures precisely so that the upper and lower lips of the incision are slightly averted to facilitate wound healing and minimize scar formation.
A total of 110 eyes from 55 patients, comprising 29 boys and 26 girls, with a mean age of 7.5 years were evaluated in the study. Of the cases, 53 were primary procedures, while two involved recurrent surgeries. In terms of cosmetic satisfaction, 49.1%of the patients were very satisfied, 27.3%were satisfied, 20%were neutral, and 3.6%were dissatisfied.
During the six month follow up, 3.6%of the patients developed recurrent eyelash corneal contact due to inward directed eyelashes, and one eye showed mild nasal entropion involving one to two eyelashes.
