Methods A total of 54 patients diagnosed to have BPPV during June 2009 to June 2010 underwent bithermal caloric test and pure tone test before particle repositioning maneuver. Then, we analyzed the clinical features of the test results. Results The course of 40 patients with canal paresis (CP) was (4.25±2.75) weeks, which had a significant difference from the course of 14 patients with CP in the abnormal side, which was (9.21±5.85) weeks (t=4.235, Plt;0.05). Among the 39 patients with posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV), 11 cases of canal paresis were found in the abnormal ear, and of the 15 patients with horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV), 3 cases of canal paresis were found. There was no statistical difference in the rate of canal paresis between the two groups of patients mentioned above (χ2=2.679,Pgt;0.05). Sixteen out of the 39 PSC-BPPV patients and seven out of the 15 HSC-BPPV patients had hearing loss (HL) in the abnormal ear with no statistical difference between the two groups of patients in the incidence of hearing loss (χ2=0.141,Pgt;0.05). Conclusion The incidence of CP and HL in the abnormal ear of patients with HSC-BPPV and PSC-BPPV is similar, and patients with long course of disease are more likely to have CP.
