title: Supraestructure maxillectomy and orbital exenteration for treatment of basal cell carcinoma of inferior eyelid: case report and review.
abstract: Basal cell carcinoma (BCC) is the most frequent type of skin cancer in humans, with cumulative exposure to ultraviolet radiation (UVR) as important risk factor for development of the illness as such as severe solar burns during childhood or adolescence. BCC is mainly located on sun exposed sites, being head and neck the areas of more incidence; although nose, eyelids and periorbitary tissue are unfavorable due to cosmetic results that BCC involves. Tumors can be classified as: nodular, superficial, micronodular, morphea variety, infiltrating, pigmented, metatypic and fibroepithelioma of Pinkus. Several treatment options as surgical and non-surgical are available. The goal of treatment is complete excision of the tumor with preservation of surrounding structures in a way aesthetically acceptable. Mohs' micrographic surgery is the standard treatment for all non-melanoma skin cancer. Orbital exenteration is also used for treatment of malignancies of ocular tissues, mainly squamous cell carcinoma, sebaceous cell carcinoma and BCC. The tissue beneath the surgical site can be left for second-intention granulation or covered with a cutaneous implant of partial thickness. The case of a 77 year-old patient is presented with BCC of inferior eyelid of 14 years duration, formerly managed with radiotherapy and, due to recurrent illness and invasion to the maxillary antrum; he needed supraestructure maxillectomy with left orbital exenteration.
