A prospective study was performed to compare the relative ability of sphenoidal (SP), nasopharyngeal (NP), and ear electrodes for detecting mesial temporal lobe epileptiform discharges. Forty-four EEGs were performed on patients with complex partial seizures, simultaneously recording from NP, SP, and ear electrodes. Spikes were noted in SP derivations in 25 records, in ear derivations in 23 records, and in NP derivations in 20 records. A total of 875 spikes were counted, SP showing 99%, NP 57%, and ear 54% of discharges, with greatest amplitudes generally seen in SP derivations. The Mann-Whitney rank sum test showed SP electrodes superior to both NP and ear electrodes (p less than 0.0001) and no significant differences between NP and ear electrodes. We conclude that SP electrodes are superior to both NP and ear electrodes in detecting mesial temporal spikes.
进行了一项前瞻性研究，以比较蝶骨电极（SP）、鼻咽电极（NP）和耳部电极检测颞叶内侧癫痫样放电的相对能力。对44例复杂部分性癫痫患者进行了脑电图检查，同时记录NP、SP和耳部电极的情况。在25份记录中，SP导联记录到棘波，23份记录中耳部导联记录到棘波，20份记录中NP导联记录到棘波。共计数875个棘波，SP导联显示99%的放电，NP导联显示57%，耳部导联显示54%，放电幅度最大的通常见于SP导联。Mann-Whitney秩和检验显示SP电极优于NP电极和耳部电极（p<0.0001），NP电极和耳部电极之间无显著差异。我们得出结论，在检测颞叶内侧棘波方面，SP电极优于NP电极和耳部电极。
