AbstractFrameless stereotactic techniques combined with a high-resolution neuro-imaging made its possible for us to perform, with high reliability, interactive image-guided procedures. We used the Carl Zeiss Surgical Microscope Navigator System with Carl Zeiss OPMI NC-4 microscope. We reported our results on the first 82 patients during the 20-month period. 36 were males (44%), 46--females (56%) with the age range of 15 to 79 (mean 43.43). The predominant diagnosis was tumor (60 patients or 73.2%) with histological findings of astrocytoma and metastasis. The surgical procedure was open microneurosurgery. There were no significant technical problems. The clinical and surgical results were satisfying in all cases. 14 patients with secondary epilepsy, as the only symptom, were postoperatively seizure-free. Neuronavigation cuts the time of surgery and ensures a more radical resection of pathological tissue with lower mortality and morbidity thus improving the life quality of patients.
