ABSTRACT
OBJECTIVE@#The objective of this study was to evaluate the utility of vestibular autorotation test in the diagnosis of BPPV.@*METHOD@#VAT and caloric test were performed on 41 patients with BPPV. VAT results were analyzed according to the affected semicircular canal.@*RESULT@#Results of VAT were abnormal in 34 (82.93%) patients with BPPV. Fourteen cases were found with abnormal vertical phase, 1 case with abnormal vertical gain in a total of 21 vertical semicircular canal BPPV patients. Six cases with abnormal horizontal phase lead, 5 cases with abnormal horizontal gain, 2 cases with asymmetry were found in 12 patients with horizontal semicircular canal BPPV. Phase lead was abnormal in all frequencies in 4 patients, and in 2-3 Hz in 21 patients. 24 (58.54%) patients showed abnormal canal paresis (CP) and direction preference (DP) in caloric test.@*CONCLUSION@#VAT can indicate information of vestibular function in both vertical and horizontal semicircular canal. Phase of VAT is constantly enhanced in BPPV, especially in 2-3 Hz. As the supplement of caloric test, VAT may prove helpful in assessment of semicircular canal function.
