Reconstrução de defeitos da concha auricular

Abstract

O pavilhão auricular é particularmente suscetível a danos actínicos e é um local comum de aparecimento de tumores epiteliais, nomeadamente carcinoma espinhocelular e carcinoma basocelular, devido à exposição cumulativa a radiação ultravioleta. A concha auricular é uma subunidade cosmética frequentemente afetada por cancro cutâneo.A excisão desses tumores é feita pela técnica cirúrgica clássica ou por cirurgia micrográfica de Mohs, e leva à criação de defeitos cirúrgicos primários com extensão e profundidade variáveis.Devido à elaborada conformação tridimensional do pavilhão auricular, a maioria desses defeitos exige o uso de retalhos e enxertos de pele para restaurar a aparência e função da aurícula.As restaurações da concha auricular incluem as seguintes técnicas: cicatrização por segunda intenção, enxertos de pele (de espessura total ou parcial) e retalhos cutâneos locais.Nenhuma destas técnicas está inerente de complicações pós-operatórias, contudo algumas podem ser evitadas. Estas complicações podem ser divididas em precoces ou tardias, surgindo nos primeiros 14 dias após a cirurgia ou depois desse período de tempo, respetivamente.O principal objetivo deste estudo é realizar um artigo de revisão sobre os métodos cirúrgicos usados na reconstrução de defeitos auriculares após a excisão de neoplasias cutâneas na concha auricular e salientar a importância deste tema, pois trata-se de um local frequentemente afetado por cancro cutâneo e a excisão completa seguida de uma reconstrução esteticamente satisfatória é de primordial importância.

The ear is particularly susceptible to actinic damage and is a common site for the appearance of epithelial tumors, namely squamous cell carcinoma and basal cell carcinoma, due to cumulative exposure to ultraviolet radiation. The conchal bowl is a cosmetic subunit often affected by skin cancer.Excision of these tumors is done by the classic surgical technique or by Mohs micrographic surgery and leads to the creation of primary surgical defects with varying length and depth.Due to the elaborate three-dimensional conformation of the pinna, most of these defects require the use of flaps and skin grafts to restore the appearance and function of the auricule.The conchal bowl reconstruction includes the following techniques: healing by second intention, skin grafts (full or partial thickness) and local skin flaps.None of these techniques are inherent to postoperative complications, however some can be avoided. These complications can be divided into early or late, appearing in the first 14 days after surgery or after that period, respectively.The main objective of this study is to carry out a review article on the surgical methods used in the reconstruction of ear defects after excision of cutaneous neoplasms in the concha and to emphasize the importance of this theme, as it is a site frequently affected by skin cancer and complete excision followed by aesthetically satisfactory reconstruction is of paramount importance. .
