Objective: The aim of this study is to investigate the vestibular evoked myogenic potentials (VEMP) findings in posterior semicircular canal benign paroxysmal positional vertigo (BPPV) patients.
Methods: Twenty patients with posterior semicircular canal BPPV and 20 healthy control subjects were recruited to participate in this study. VEMP was performed at diagnosis and after treatment.
Results: All the volunteers in the control group and 15 patients in BPPV group showed a VEMP response in both ears. The P1, N1 latencies showed a significant difference between BPPV patient’s affected ears and control subjects. There were no significant differences between the unaffected ears of BPPV patients and control subjects with respect to P1, N1 latencies. P1, N1 latencies showed no significant difference between affected and unaffected ears in BPPV patients. No significant difference could be found between the pre and post treatment values of P1, N1 latencies in BPPV patients.
Conclusions: Our findings showed significantly more abnormal VEMP results in the BPPV than in the control subjects.
