Comparison of delta facial nerve motor-evoked potential (FNMEP) between the facial nerve function reservation group and the facial nerve function damage group, (A) based short-term facial nerve function assessment, the delta FNMEP in the facial nerve function reservation group (n = 84) was significantly lower than those in the facial nerve function damage group (n = 12) (P < .001). (B) Based long-term facial nerve function assessment, the delta FNMEP in the facial nerve function reservation group (n = 92) was also significantly lower than those in the facial nerve function damage group (n = 5) (P < .001).
