Lower eyelid ectropion as a sequela of different underlying diseases in maxillo-facial surgery: Diagnostics and treatment approaches.

Purpose: This study investigated the outcome of lower eyelid ectropion (LEE) treatment in patients with another primary periorbital or mid-facial pathology.

Materials And Methods: This 18-year monocentric retrospective cohort study included patients admitted for various leading mid-facial pathologies and presenting with a LEE. The primary diagnosis, surgical pretreatment, ectropion type, ectropion severity score (ESS), and surgical techniques were recorded. The primary endpoint was the postoperative ESS score.

Results: Overall, 40 patients (female n = 16, male n = 24, average age 70.8 years), primarily with periorbital skin cancer (n = 21, 52.5%), facial palsy (n = 7, 17%), trauma (n = 6, 15%), or other pathologies (n = 6, 15%), were included. Surgical procedures mostly addressed a correction of anterior and posterior lamellae (n = 22, 55%), with isolated anterior lamellae in only a few cases (n = 10, 25%). The ESS score significantly decreased from 4.8 ± 1.8 to 1.3 ± 1.3 (paired t-test, p < 0.001) after a mean follow-up of 23.8 months.

Conclusion: LEE constitutes a relevant problem. Due to preexisting canthal ligament laxity in patients undergoing oncologic or traumatic midface surgery, the risk of ectropion has so far been underestimated. Bilamellar approaches in elderly patients are likely to be obligatory in any case.
