Reconstruction of a helical rim defect following excision of squamous cell carcinoma in the ear by chondrocutaneous advancement flap

초록

About three percent of all skin cancers occur on the helix of the ear. Excision of the cancer results in a defect of the helical rim. Primary closure and wedge excision may produce cupping and helical notching deformities, except in small defects. In 1967, Antia and Buch described a chondrocutaneous advancement flap for marginal defects of the ear. This technique provides a reliable single-stage procedure an excellent cosmetic result. We report a case of squamous cell carcinoma on the helical rim, of which the surgical defect was repaired with a chondrocutaneous advancement flap.
