Objective: To investigate the clinical value of two kinds of vestibular evoked myogenic potentials in patients with sudden hearing loss.
Methods: 82 patients were divided into two groups, accompanied with vertigo group and without vertigo group. All the cases were examined pure tone hearing thresholds, middle ear analysis, video nystagmus electrical diagram, caloric tests and vestibular evoked myogenic potentials elicited from the sternocleidomastoid and extraocular muscle respectively. 30 healthy subjects were selected as the control group.
Results: In 30 healthy subjects, the average latency of p13 and n23 of the cVEMPs were 13.13 ± 2.89 ms and 23.51 ± 3.25 ms respectively and the bilateral amplitude asymmetry rate was from 0.05 to 0.31. The average latency of n10 about the oVEMPs was 10.13 ± 0.48 ms. The average amplitude of n10-p15-wave was 5.58 ± 0.65μV. Among the 35 cases of sudden deafness with vertigo patients, 27 patients were normal in cVEMPs and oVEMPs examinations, five cases were abnormal in oVEMPs, and five cases were abnormal in cVEMPs. The latency and the amplifier of oVEMPs and cVEMPs were within the normal range in the 47 patients with sudden hearing loss without vertigo. The chisquare with SPSS17.0 software was analyzed between the two groups. The chi-square values were all 5.647, and the p-values were the same 0.017, the difference was statistically significant at the 95% confidence interval.
Conclusion: OVEMPs and cVEMPs can evaluate the vestibular nerve function of patients with sudden hearing loss accompanied with vertigo.
