The basal cell carcinoma is the most frequent tumor of the auricular pavilion, followed by the squamous cell carcinoma. The embrionary fusion planes of the ear zone offer little resistance to tumoral dissemination. The biological behavior of the basal cell carcinoma is locally aggressive, while the squamous cell carcinoma tends to metastise via the lymphatic and neurotropic systems. Cryosurgery is an adequate method for the treatment of basal cells and squamous cell carcinomas located in the auricular pavilion. It allows us to control them keeping its anatomical and functional integrity. Our statistics agree with the ones published by authors that use other surgical methods. We present 78 cases treated from 1985 to 1995. Of these, 64 were basal cell carcinomas and 14 were squamos cell carcinomas. Cryosurgery was used in 67 cases, cryosurgery and radiofrequency in 9 cases and combined surgery in 2 cases.
