A comparison of residual dizziness between primary benign paroxysmal positional vertigo and secondary benign paroxysmal positional vertigo

Objective To compare the difference in incidence rates,duration and the score of dizziness handicap inventory(DHI) of residual dizziness between parents with primary benign paroxysmal positional vertigo(BPPV) and the patients with secondary BPPV,and provide reference for the clinical treatment of secondary BPPV. Methods According to the etiology,196 cases of BPPV undergoing particle repositioning maneuvers in our hospital between May,2012 and December,2015 were enrolled and divided into secondary BPPV group(n=73)and primary BPPV group(n=123).The gender,age,the course before repositioning treatment,incidence rates and duration of residual dizziness,and the score of DHI were analyzed. Results There were no significance between the two groups in the gender,age,the course before repositioning treatment(P>0.05).The incidence rates of residual dizziness in secondary BPPV group was higher than that in primary BPPV group(65.75% vs. 49.45%,P<0.05).The duration of residual dizziness in secondary BPPV group was longer than that in primary BPPV group[(11.54±4.15)d vs. (9.21±4.54)d,P<0.05].The secondary BPPV group had a higher score of DHI(18.44±6.67 vs. 14.79±6.00,P<0.05). Conclusion The secondary BPPV patients had higher incidence rates,longer duration and high DHI score of residual dizziness.In our clinical work,we should attach more importance to the secondary BPPV patients.The early intervention of residual dizziness will improve the quality of life of BPPV patients.
