Factors associated with the etiological uncertainty of drug reactions: a cross-sectional study in southern Brazil


An. Bras. Dermatol.




Abstract Background: The ear is a region that has a high prevalence of cutaneous carcinomas and several guidelines indicate Mohs micrographic surgery as the first-choice treatment in such cases. Although the technique allows maximum preservation of healthy tissue, many auricular surgical wounds constitute a challenge due to the peculiar local anatomy, with evident curves and reliefs. Auricular reconstruction should prioritize function before aesthetics, but without leaving the latter aside, since postoperative distortions can have a significant psychological impact. Objective: To describe the authors’ experience in auricular reconstruction after Mohs surgery and to evaluate the most frequently used repair methods. Methods: Retrospective study of consecutive cases submitted to Mohs surgery and auricular reconstruction, over a period of 3 years. Results: One hundred and one cases were included and the most common repair method was primary closure (n = 35), followed by full-thickness skin graft (n = 30) and flaps (n = 24). In thirty cases, reconstruction methods were associated. Seven patients had complications (partial graft necrosis, postoperative bleeding or infection). Study limitations: Retrospective design and the absence of long-term follow-up of some cases. Conclusions: The dermatologic surgeon should be familiarized with different options for auricular reconstruction. Primary closure and skin grafts were the most frequently used repair methods.
