Lid margin split in the surgical correction of epiblepharon

Abstract

To describe the technique of splitting the lid margin combined with the excision of redundant skin and muscle during the surgical correction of epiblepharon and to report its clinical outcome. A combined procedure that included splitting the lid margin to repair lower eyelid epiblepharon was performed on 31 eyes of 19 consecutive patients. Lid margin splitting was performed along the grey line on the medial third or half of the lower eyelid by making a 1 mm-deep incision. Having made a transverse subciliary skin incision and a dissection between the tarsus and the orbicularis oculi muscle, the subcutaneous tissue of the superior edge of the incision was secured to the tarsus with interrupted sutures to evert the cilia. An excision of the redundant skin and orbicularis tissue was made and the skin was closed. The patients were followed for direct inspection of the wound, the split lid margin, the direction of the lashes and the status of the cornea. The mean postoperative follow-up period was 29.4 weeks. Symptoms disappeared in all patients. In 30 eyelids of 19 patients the cilia did not touch the cornea, even in the down-gaze. In one eyelid the cilium touched the medial conjunctiva, but not the cornea. The cosmetic outcome of the lower lid was satisfactory in all cases and the wounds of the split lid margin healed without scarring. To date, there have been no complications such as wound dehiscence, ectropion or eyelid retraction. The lamellar splitting of the lid margin is a beneficial addition to the repair of prominent lower lid epiblepharon, especially on the medial aspect of the eyelid. This simple technique ensures easier eversion of the cilia in epiblepharon repair, without disturbing the posterior lamella or causing unfavourable results.
