Placement accuracy of deep brain stimulation electrodes using the NexFrame© frameless system

Original language description

Background: Various methods are used to target nuclei of basal ganglia, including direct visualization of preoperative magnetic resonance images, intraoperative microelectrode recording and anatomical target coordinates. A frame-based stereotaxy or a framelessstereotactic system (NexFrame©) are used during electrode placement. Accurate electrode placement is necessary for correctly functioning deep brain stimulation (DBS). The objective of the study was to evaluate placement accuracy of DBS electrodes using the NexFrame© frameless navigation system in our department. Methods: Coordinates of the planned target point according to anterior and posterior commissural points are found using preoperative MRI of the brain and are usually modified intraoperatively according to microrecording and clinical examination. The coordinates of the actual position of the electrode are detected using a fusion of preoperative MRI with postoperative CT. To determine placement accuracy of the electrodes, the total error and lateral, anteroposterior, and vertical errors were calculated. Results: A total of 70 DBS electrodes were implanted using the NexFrame© system in 35 patients dia gnosed with Parkinson?s disease, essential tremor, or dystonia (mean age 62. 1 ± 8. 3) between June 2013 and January 2016. The mean total error was 1. 64 ± 0. 81 mm, the mean lateral error was 1. 03 ± 0. 79 mm, the mean anteroposterior error was 1. 14 ± 0. 95 mm, and the mean vertical error was 1. 05 ± 0,91 mm. Results were compared to the results of other studies and we conclude that the frameless Nexframe© system is fully comparable to frame-based systems.
