  • Title: Modified Antia-Buch flap for the reconstruction of helical rim defects.
    Author: Noel W, Leyder P, Quilichini J.
    Journal: J Plast Reconstr Aesthet Surg; 2014 Dec; 67(12):1659-62. PubMed ID: 25193398.
    Abstract:
    BACKGROUND: The Antia-Buch flap is a sophisticated one-stage procedure using two chondrocutaneous flaps to reconstruct the ear helix. Because tissue laxity is largely conferred by the inferior flap, relative to the less mobile superior flap, chondrocutaneous resection of scapha is required for closure. This results in loss of ear height and limits morphologic outcome. We describe a modification of the Antia-Buch flap, which may avoid such drawbacks. PATIENTS AND METHOD: We conducted a retrospective review of patients (n = 15), each undergoing our modified Antia-Buch flap between 2010 and 2014. All procedures were performed under local anesthesia as outpatient procedures. Data on magnitude of resections, procedure durations, related complications, and aesthetic outcomes were collected. RESULTS: The mean size of resection was 25 mm (range, 20-30 mm). The modification improved the mobility of the upper chondrocutaneous flap, eliminating the need to resect the scapha. All wounds healed uneventfully, with no skin necrosis. The morphologic outcome was satisfactory or very satisfactory in all patients, preserving the shape, height, and width of the ear. CONCLUSIONS: Our modification changes the upper flap from an advancement flap to a transposition flap, enhancing its mobility and preempting the resection of the scapha. Thus, anatomic landmarks, aesthetic subunits of the pinna, and ear height are maintained for highly satisfactory morphologic results. LEVEL OF EVIDENCE: 4.
