Navigation in surgical treatment of anteriolateral skull base tumors with extracranial extension

Le résumé fourni par la source

During surgical treatment of tumors of the anterolateral skull base with extracranial extension, anatomical landmarks can be easily lost during the operation. The use of intraoperative navigation methods plays an important role in solving this problem. Materials and methods. The results of treatment of 70 patients with tumors of the anterolateral skull base with extracranial extension, operated on using intraoperative navigation (36 interventions, study group) and without navigation (34 interventions, control group) at the N. N. Burdenko National Medical Research Center of Neurosurgery from 2016 to 2021, were analyzed. Results. After statistical analysis using the pseudo-randomization method, 24 observations were found in both groups and a statistically significant difference was obtained in favor of the group with navigation. In primary interventions, tumor remnants were not detected in 15 cases (71 %) in the navigation group and in 8 cases (31 %) in the nonnavigation group, and the differences were statistically significant. No statistically significant differences were found in the repeat intervention group: there were no remnants available for removal in 3 cases in the study group and in 1 case in the control group. Conclusion. Intraoperative navigation increases the probability of removing accessible tumor areas. The work is based on the dissertation of V. V. Nazarov «Application of navigation in surgery of tumors of the anterolateral parts of the skull base with extracranial spread», place of hearings of the Federal State Autonomous Institution «Burdenko National Medical Research Center of Neurosurgery» of the Ministry of Healthcare of the Russian Federation, date of hearings 04/23/2024.
