Porous polyethylene for the reconstruction of severe Cosman cleft ear deformities

Abstract

“Cosman ear,” “question mark ear,” or “auricular cleft between the fifth and six hillock” are synonyma for a congenital malformation between the helix and the lobule. While there is no definitive surgical method for correction of this deformity, there is agreement that only minor forms can be satisfyingly corrected with local skin flaps, whereas severe deformities need autologous cartilage or similar for reconstruction. The present publication describes a new method to correct a bilateral severe Cosman cleft ear deformity with a porous polyethylene framework and a postauricular fascia flap, leading to an appealing aesthetic result.
