Abstract

Histopathological diagnosis of the intraorbital tumors is of crucial value for planning further conservative or surgical treatment. Small intraorbital lesions located posteriorly to the bulb, intraconally or in the orbital apex are extremely difficult to reach via traditional external approach. Precise fine needle aspiration in these cases is not easy and a small amount of examined material may lead to misdiagnosis.

The aim of the study was to evaluate the usefulness of nasal endoscopy and image guided neuronavigation system in the diagnosis of orbital tumors. Seven patients with intraorbital tumors were diagnosed. All the lesions were precisely localized and the biopsy was succesfully taken using transnasal endoscopy supported by neuronavigation system. None of the patients developped ocular symptoms aggravation after the procedure. Neuronavigation system facilitated precise localization of the lesion, helped to protect vulnerable orbital structures and decreased the risk of complications.
