Non-melanoma skin cancer is the most common type of neoplasia. Basal cell carcinoma is the most common cancer of them, the incidence of which is steadily increasing, implying an important public and financial health issue. The authors present the case of a patient with an extensive basal cell carcinoma affecting part of the external auditory canal and auricular concha, treated with a combination of surgical techniques: flap-plasty associated with second intention closure of the external auditory canal. Due to the excellent aesthetic and functional outcomes, this technique should be considered as a therapeutic option for auricular lesions.

Non-melanoma skin cancer is the most common neoplasia in humans, and basal cell carcinomas (BCC) account for approximately 80% of cases. Cumulative exposure to ultraviolet radiation (UV) is the main risk factor associated to BCC, with a higher incidence in photoexposed areas, including the auricular region. The auricular region is a noble cosmetic unit, with anatomical peculiarities that lead surgeries to require the excision of a large amount of tissue, presenting a challenge for the dermatological surgeon. The authors present a case of helix reconstruction with a triple transposition flap.
