Reconstrucción auricular mediante fenestras y curación por segunda intención con apósitos hidrocoloides después de una cirugía micrográfica de Mohs

Abstract

IntroductionMohs micrographic surgery plays a prominent role in cutaneous carcinomas treatment allowing 100% control of surgical margins. Reconstruction of surgical defects is quite a challenge for the dermatological surgeon. There are particularly complex anatomical regions such as the auricule. Auricular fenestration with subsequent secondary-intention healing is a simple, economical technique, with few complications, that is useful when the defect involves the cartilage and its perichondrium. Materials and methodsA descriptive study of auricular defects after Mohs micrographic surgery was carried out using the auricular fenestration technique and healing by second-intention healing assisted with hydrocolloid dressing. ResultsWe present four patients with an average age of 68.5 years, three of them presented basal cell carcinoma and one presented squamous cell carcinoma. The average size of repaired defects was 2.45 cm. ConclusionThe procedure was well tolerated and none of the cases presented complications such as bleeding or infection.
