Application of the navigation system in endoscopic surgery of paranasal sinuses and base of the skull

The intraoperative navigation computer system Stealth Station is an effective technique of stereotactic guidance during endoscopic endonasal interventions. Use of navigation allows performance of a radical operation without damaging basic anatomical structures of the base of the skull (vision nerve, cribriform lamina, internal carotid arteries, cavernous sonus, etc.). In rhinosurgery, Stealth Station is indicated in borderline pathology of the paranasal sinuses and base of the skull. Ten cases of patients with combined pathology of the paranasal sinuses and base of the skull, cases of endoscopic endonasal removal of the lesions of the base of the skull and foreign bodies with application of the navigation system are reported.
