Auricular reconstruction after Mohs micrographic surgery: analysis of 101 cases

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.

Adenocarcinoma em pavilhão auricular de uma felina / Adenocarcinoma in a feline auricular pavilion

Um felino não definido foi admitido no HOVET / UFRA com desidratação e extenso traumatismo craniano próximo à aurícula esquerda. Foi observada uma massa localizada próxima à base das orelhas. Após verificar que o animal não melhorou a cicatrização, foi escolhida uma técnica de excisão por conchectomia. O material foi enviado para exame histopatológico, que mostrava diagnóstico morfológico de adenocarcinoma de provável origem apócrina grau II / III. A radiação ultravioleta da luz solar é um fator que pode contribuir para a formação de carcinoma espinocelular nas extremidades das orelhas de gatos de vida livre com pelagem leve.(AU)

A no defined bred feline was admitted to the HOVET/UFRA with dehydration and extensive head injury near the left auricle. A mass located near the base of the ears was observed. After verifying that the animal did not improve healing, an excision by conchectomy technique was chosen. The material was sent for histopathological examination, which showed a morphological diagnosis of adenocarcinoma of probable grade II / III apocrine origin. Ultraviolet radiation from sunlight is a fator that can contribute to the formation of squamous cell carcinoma on the ends of the ears of free-living cats with light coat.(AU)
