Repair of 50-75% full-thickness lower eyelid defects: Lateral stabilization as a guiding principle.

Abstract

Introduction:Repair of large defects of the lower eyelid can be difficult. A common procedure performed to address these defects is a Hughes flap. This procedure has a number of disadvantages: The eye is closed postoperatively, a second stage is required, and the edge of the flap is often erythematous. The purpose of this paper is to describe a one-stage procedure for the repair of large full-thickness defects of the lower lid as an alternative to a Hughes flap.Materials and Methods:This is a retrospective study of patients who underwent the described procedure. The procedure employs lateral stabilization of the posterior lamella with a periosteal strip, medial transposition of the lateral posterior lamella for central and medial defects, and a myocutaneous advancement flap to stabilize the anterior lamella.Results:A total of 38 patients underwent the procedure to reconstruct full-thickness defects of the lower lid ranging from 50% to 75%. All patients underwent previous Mohs excision of a skin cancer. The average follow-up was 5.6 months. Eleven patients (29%) had postoperative sequelae, but only two patients (5%) required additional treatment.Conclusion:Lateral stabilization with a periosteal strip and myocutaneous advancement flap is an excellent one-step procedure that avoids many of the complications seen with the Hughes procedure and is comparable to other techniques used for the reconstruction of subtotal, full-thickness lower lid defects.
