Abstract:
OBJECTIVE To analyze the caloric test findings of the unilateral primary horizontal and posterior semicircular canal benign paroxysmal positional vertigo(HSC-BPPV and PSC-BPPV).METHODS Caloric test were tested in 152 PSC-BPPV patients and 25 HSC-BPPV patients after Dix-Hallpike test and Roll test.RESULTS Of 152 PSC-BPPV patients 64 canal paresis(CP)were found in the abnormal side and 44 in the normal side;Of 25 HSC-BPPV patients 16 canal paresis were found in the abnormal side and 9 in the normal side.The incidence of CP in PSC-BPPV is 30.3% and the incidence of CP in HSC-BPPV is 52%.13 Patients with PSC-BPPV were found abnormal Directional Preponderance(DP)and 10 Patients with PSC-BPPV were found abnormal Directional Preponderance.CONCLUSION The incidence of CP in the abnormal side of HSC-BPPV and PSC-BPPV is more than that of the normal side.The incidence of CP in abnormal side of the HSC-BPPV is more than that of PSC-BPPV.The incidence of abnormal DP in HSC-BPPV is more than that of PSC-BPPV.
