Objective * To explore the diagnostic value of blink reflex combined with trigeminal somatosensory evoked potential (TSEP) in trigeminal neuralgia. Methods * A total of 147 patients with trigeminal neuralgia were enrolled as the research objects between February 2022 and February 2023. After admission, all underwent blink reflex on affected/healthy sides and TSEP examinations. The diagnostic value of the blink reflex combined with TSEP was analyzed. Results * The latency of RI, R2, and R2' waves (refers to the different nerve signal waveforms that are recorded when a facial nerve conduction speed test is performed) on the affected side was significantly longer than that on the healthy side (t = 26.324,18.391,20.801,Ps<.001), and latency of Wl, W2 and W3 waves was also significantly longer than that on the healthy side (t = 16.045, 10.814, 10.349, P<.001). The results of Pearson correlation analysis showed that the latency of RI, Wl, W2, and W3 waves was positively correlated with the VAS score (r = 0.539, 0.611, 0.577, 0.586, P<.001). The results of receiver operating characteristic (ROC) curves analysis showed that area under the curve (AUC) values of RI, R2, R2', Wl, W2, and W3 waves latency on the affected side in the diagnosis of trigeminal neuralgia were 0.753, 0.634,0.651,0.748,0.756 and 0.736, respectively. The AUC of combined detection was 0.926, significantly greater than that of the single index (P< .001). Conclusion * Blink reflex combined with TSEP monitoring can improve the diagnostic value of trigeminal neuralgia, and the latency is related to pain. (Altern Ther Health Med. 2023;29(8):352-355).
