Case in brief
A pediatric patient developed cicatricial lower eyelid ectropion after two local excisions of a congenital melanocytic nevus at another institution. Definitive reconstruction used a temporally based orbicularis oculi myocutaneous flap, oriented from the lateral canthus toward the temple to provide upward traction and muscular support. The flap had stable perfusion, and the ectropion was corrected. At follow-up, eyelid margin position remained stable with satisfactory symmetry.
What made this case unusual
The reconstruction used a temporally based orbicularis oculi myocutaneous flap, designed to combine an upward traction vector with added muscular support for postexcisional cicatricial ectropion.
Diagnostic / clinical pearl
In postexcisional lower eyelid ectropion with cicatricial traction, assess the need for structural support as well as skin coverage; this case describes correction with a temporally based orbicularis oculi myocutaneous flap.
