RESUMO
OBJECTIVES: To determine the role of transnasal endoscopic approach to orbital lesions. METHODS: Retrospective case series. RESULTS: Three patients underwent endoscopic diagnostic surgery for orbital lesions. In all three patients was successfully finded out the diagnosis, the orbita was decompressed. In two cases it resulted to visual recovery, in one case was determine a diagnosis of metastatic adenocarcinoma. In one case the tumor was removed totally. CONCLUSION: Using endoscopic approach to the orbit allowed good approach to the biopsy of orbital lesions, allowed decompression an in limited count of cases this access allowed a complete tumour removal. On the other hand, generally endoscopic approach is useful only for limited lesions (extraconal), usually it allowed only debunking, not the complete resection of orbital pathology.
