ABSTRACT
Objective:
To describe causes of orbital exenteration in a Brazilian tertiary hospital.
Methods:
A retrospective study was done, involving patients submitted to orbital exenteration at the Clinical Hospital of Botucatu Medical School, between the years of 1993 to 2016. The surgeries have been performed under general anesthesia, by a multidisciplinary team, composed by ophthalmologists, otolaryngologists and head and neck surgeons.
Results:
Fourteen cases of orbital exenteration occurred in the period of the study, with a mean age of 63.36 ± 13.18 years and nine were men (64.3%). All exenteration were due to malignant tumors, being more frequent the squamous cell carcinoma (7 cases - 50.0%). The most common primary sites were the eyelids (50.0%) followed by the conjunctiva (28.6%). The majority of the surgeries was extended exenteration type (57.1%) and most of the reconstructions was made by spontaneous granulation (64.3%). The survivor rate in 1 year was 78,6% and in 5 years was 71.4%.
Conclusion:
The main cause of orbital exenteration was squamous cell carcinoma and the most frequent primary site was the eyelids. Extended exenteration was necessary for the majority of cases, most of them with free margins.
