Journal ArticleDOI
Directional deep brain stimulation: an intraoperative double-blind pilot study.
Claudio Pollo,Alain Kaelin-Lang,Markus Florian Oertel,Lennart Stieglitz,Ethan Taub,Peter Fuhr,Andres M. Lozano,Andreas Raabe,Michael Schüpbach +8 more
TL;DR: Directional deep brain stimulation with a reduced electrode size applied intraoperatively in the subthalamic nucleus as well as in the nucleus ventralis intermedius of the thalamus significantly widened the therapeutic window and lowered the current needed for beneficial effects, compared to omnidirectional stimulation.
Journal ArticleDOI
The warning-sign hierarchy between quantitative subcortical motor mapping and continuous motor evoked potential monitoring during resection of supratentorial brain tumors.
TL;DR: In this paper, the authors compared subcortical monopolar stimulation thresholds (1 − 20 mA) with direct cortical stimulation (DCS)-motor evoked potential (MEP) monitoring signal abnormalities and to correlate both with new postoperative motor deficits.
Journal ArticleDOI
The silent loss of neuronavigation accuracy: a systematic retrospective analysis of factors influencing the mismatch of frameless stereotactic systems in cranial neurosurgery.
Lennart Stieglitz,Jens Fichtner,Robert H. Andres,Philippe Schucht,Ann-Kathrin Krähenbühl,Andreas Raabe,Jürgen Beck +6 more
TL;DR: There is an ongoing loss of neuronavigation accuracy after registration, and surgeons should be aware of this silent loss of accuracy when using neuronsavigation.
Journal ArticleDOI
Reliability of intraoperative high-resolution 2D ultrasound as an alternative to high-field strength MR imaging for tumor resection control: a prospective comparative study.
TL;DR: Intraoperative MR imaging is more precise in detecting small tumor remnants than 2D ultrasound, and the latter may be used as a less expensive and less time-consuming alternative that provides almost real-time feedback information.
Journal ArticleDOI
Microvascular decompression for trigeminal neuralgia in the elderly: long-term treatment outcome and comparison with younger patients.
TL;DR: MVD for TN is a safe procedure even in the elderly and the risk of serious morbidity or mortality is similar to that in younger patients, and no significant differences in short- and long-term outcome were found.
