ABSTRACT

Objective: to describe the clinical and pathological characteristics and the results obtained in patients undergoing orbital exenteration.
Methods: a descriptive, case series and retrospective study was carried out at the Institute of Oncology and Radiobiology from January 2011 to December 2016. The sample of 71 exenterated patients was characterized according to age, sex, origin of the lesion, histopathological diagnosis, previous treatments, type of orbital exenteration, state of the surgical section edges, adjuvant treatments, associated surgical approaches, reconstruction of the cavity and postoperative complications.
Results: in this sample, 67.6 % of the studied sample were men, 43.7 % were in the 60-79 age group; the primary lesion of 38 % was located in the eyelids and and the histopathological diagnosis in 56.3 % of patients was squamous cell carcinoma. One hundred percent of the sample had received some type of previous medical treatment, 69 % of the sample underwent type III orbital exenteration, and only in 15.5 %, the surgical section edges were reported as positive. Also, 29.6 % received adjuvant treatment with radiotherapy. The combination with other surgical approaches was required in 28.2 % of patients and % spontaneous healing of the orbital cavity was allowed in 69 %. The sino-orbital fistula was the most frequent complication (8.5 %).
Conclusions: squamous cell carcinoma is the periocular tumor that most frequently invades the orbit. Most exenterated cases managed to achieve total resection of the tumor with minimal postoperative complications.
