The clinical characteristics，treatmentefect，qualityof lifeand prognosis of thetwo groups werecompared.Results Thepercentage of hypertension，thepercentage of moderate vertigo，and thepercentageof posterior hemicircular canal involvement were lower in the secondary BPPV group than in the idiopathic BPPV group，and the duration of persistent vertigo，severe vertigo，the percentage of anterior hemicircularcanal involvement，and thepercentage ofhorizontal hemicircular canal involvement were higher than those in the idiopathic BPPV group（all P <0.05）. The total effctive rate of the idiopathic BPPV group was higher than that of thesecondary BPPV group in both the first reset treatment and after 3 months of treatment （ P <0.05）.After 3 months of treatment，the Dizziness Handicap Inventory（DHI） scores of both groups were reduced，and the idiopathic BPPV group was lower than that of thesecondary BPPV group（ P <0.05）.The recurrence rate of the idiopathic BPPV group was lower than that of the secondary BPPV group （ P<0.05） .Conclusion Vertigo symptoms were more serious in patients with secondary BPPV，and the patients mostlyinvolved the horizontal or anterior semicircularcanal;the treatment success rate of idiopathic BPPV was higher and the recurrence rate was lower.
