A prospective study was performed to evaluate the usefulness of ear, anterior temporal, and nasopharyngeal electrodes for recognizing temporal lobe epileptic electroencephalographic (EEG) foci. One hundred and three EEGs were performed on patients suspected of having epilepsy who had a previous normal record. Nasopharyngeal electrodes were simultaneously compared with ear and anterior temporal electrodes to determine their relative abilities to detect pathological epileptiform transients from the temporal region. Epileptic discharges were detected in 22% of the recordings. Pathological discharges seen in nasopharyngeal electrode derivations invariably were seen in ear and anterior temporal electrode derivations using carefully designed montages, and EEG diagnosis was not altered by use of nasopharyngeal electrodes. We conclude that EEG recording with ear and anterior temporal electrodes is sufficient to detect pathological temporal epileptiform transients, and that the use of nasopharyngeal electrodes as a routine procedure offers no added benefit.
进行了一项前瞻性研究，以评估耳部、颞前部和鼻咽电极在识别颞叶癫痫脑电图（EEG）病灶方面的效用。对103例曾有正常脑电图记录、疑似患有癫痫的患者进行了脑电图检查。将鼻咽电极与耳部和颞前部电极同时进行比较，以确定它们从颞区检测病理性癫痫样瞬变的相对能力。在22%的记录中检测到癫痫放电。使用精心设计的导联方式，在鼻咽电极导联中看到的病理性放电在耳部和颞前部电极导联中均能看到，并且使用鼻咽电极并未改变脑电图诊断。我们得出结论，使用耳部和颞前部电极进行脑电图记录足以检测病理性颞叶癫痫样瞬变，并且将鼻咽电极作为常规操作并无额外益处。
