The diagnostic utility of different noninvasive electrode placements for deriving the electroencephalogram and detecting interictal epileptiform discharges was compared. Anterior temporal and nasopharyngeal electrodes in combination with routine scalp electrodes detected over 97% of the spikes, whereas recording from only standard electrode placements detected 58%. Minisphenoidal and surface sphenoidal electrodes were generally not helpful. In some circumstances, however, the use of surface sphenoidal electrodes provided important confirmatory information. In no case did the minisphenoidal electrodes provide unique information, and their use seems unjustified, although the inclusion of other nonstandard electrodes in the recording montage is important to increase the yield.
比较了不同无创电极放置方式在获取脑电图和检测发作间期癫痫样放电方面的诊断效用。前颞叶电极和鼻咽电极与常规头皮电极联合使用时，能检测到超过97%的棘波，而仅从标准电极位置记录时，检测到的比例为58%。蝶骨电极和蝶骨表面电极通常并无帮助。然而，在某些情况下，蝶骨表面电极的使用可提供重要的确诊信息。蝶骨电极从未提供过独特信息，其使用似乎并无道理，尽管在记录导联中加入其他非标准电极对于提高检出率很重要。
