The roles of otolith organs in the recurrence primary benign paroxysmal positional vertigo / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the roles of otolith organs in the occurrence and recurrence of primary benign paroxysmal positional vertigo (BPPV) by vestibular evoked myogenic potential (VEMP) test.@*METHOD@#We enrolled 17 recurrent primary BPPV patients and 42 non-recurrent primary BPPV patients between September 2014 and November 2014. All patients underwent VEMP tests, including cervical vestibular evoked myogenic potential (cVEMP and ocular vestibular evoked myogenic potential (oVEMP) tests. The abnormal case was defined as non-elicitation or asymmetry rate between bilateral sides is larger than 29%.@*RESULT@#Significant difference was found in abnormal rate between cVEMP and oVEMP (P 0.05). No significant difference was found in sex and age between recurrent and non-recurrent groups (P > 0.05).@*CONCLUSION@#The impairment of otolith organs, especially the utricle, is related to primary BPPV. Dysfunction of utricle may play a role in recurrence of BPPV. Recurrence of BPPV is not correlated with sex and age.
