Objective: To assess whether frameless stereotaxy can further increase safety and efficacy of transsphenoidal microsurgery.Methods: We conducted a retrospective analysis of 29 patients with pituitary adenomas (10 recurrent, 12 micro, 17 macro), who had undergone image guided endonasal transsphenoidal surgery during an 18-month period in the Department of Neurosurgery, Medical University - Sofia, Bulgaria. In the preoperative planning process, the adenoma volume and both carotid arteries were segmented in a MRI/CT-3 D dataset (T1-weighted, 3 D FLASH after Gadolinium). An optical infrared-based neuronavigation system (Vector Vision, BrainLAB®, Heimstetten, Germany) was used in all cases for frameless guidance. Using Z-touch infrared markerless or landmark registration (in 3 cases) a mean calculated accuracy of 1.47±0.4 mm was achieved; intraoperative accuracy was checked every 10 min. Intraoperative records were reviewed with attention to the utility of the navigational guidance.Results: The time requirements for set-up, registration and navigational control were minimal ( |
