Abstract

Aims . To describe the technique, indications, and utility of intraoperative ECoG monitoring during various surgeries for medically intractable epilepsy. Methods . Literature was reviewed to obtain published results on using intraoperative ECoG techniques for the surgical treatment of medically intractable epilepsy of various underlying aetiologies. Results . General intraoperative ECoG techniques were described, including effects of anaesthetic agents on intraoperative ECoG signals. Use of intraoperative ECoG in temporal lobe epilepsy with mesial temporal sclerosis (MTS) is generally considered not necessary, whereas intraoperative ECoG in temporal lobe epilepsy without mesial temporal sclerosis may provide useful information. Intraoperative ECoG in extra‐temporal epilepsy with structural lesions may facilitate resection, whereas the use of intraoperative ECoG in extra‐temporal epilepsy without a structural lesion is more controversial. Conclusions . Intraoperative ECoG is a useful technique to be employed in surgical treatment of medically intractable epilepsy. However, its effectiveness may vary depending on the underlying pathological causes of the seizures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
