Abstract
Objective: The aim of study is to verify whether preoperative nTMS is a reliable tool for the positioning of subdural electrodes for CCEPS recording in presence of minicraniotomy.
Methods: This is a monocentre, prospective, observational cohort study in which we included adults with lesions compressing o infiltrating the peri-sylvian area. In the pre-operative phase, we performed navigated transcranial magnetic stimulation (nTMS) to identify language areas. During the intervention we performed CCEP recordings using subdural strip electrodes positioned according to the surgical conditions or according to nTMS indications or in accordance with tractography. CCEPs were recorded continuously throughout the intervention with the exception of the phases in which it was necessary to monitor a different type of evoked potentials. To evaluate the association between the possibility of registering CCEPs and the method used for the positioning of the subdural electrodes the patients were dichotomized as CCEP present and CCEP not identifiable.
Results: We evaluated 33 subjects but only 28 were included in the analysis. No statistically significant differences were present between these two-patient group's. The CCEPs were substantially stable during the surgical procedure in 25 patients (89.3%). When strip was positioned according to nTMS (n°:24/28; 85.7%) the CCEP were always recorded while when strip was positioned according to tractography CCEP were not identifiable in 4 (14.4%).
Conclusions: Compared to tractography, nTMS shows a higher reliability in the placement of subdural electrodes used for CCEP recordings.
期刊介绍：
World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The journal''s mission is to:
-To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care.
-To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide.
-To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients.
Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
