Background & Objectives: Canalith repositioning procedure (CRP) provides rapid and long-lasting relief of symptoms in most patients with benign paroxysmal positional vertigo (BPPV). However, some patients express nonspecific symptoms such as anxiety or discomfort after CRP, even after the disappearance of nystagmus and vertigo. The purpose of this study is to assess the residual symptoms after CRP in patients with BPPV using questionnaire.
Subjects & Method: CRP was performed in 135 patients until nystagmus and vertigo disappeared, and the patients were asked to complete the Dizziness Handicap Inventory (DHI) before and five to seven days after treatment. For the control group, 135 normal volunteers were selected, and cross matched according to the age and sex with the patient group. The DHI were compared among pre CRP, post CRP and control group.
Results: There were statistically significant differences between the pre-CRP and post-CRP DHI scores and also between the post-CRP and control group. Comparison between the pre and post-CRP DHI scores, and post-CRP and control group both showed incomplete improvement with respect to some items.
Conclusions: Even after the successful CRP, DHI scores indicated incomplete recovery and residual subjective symptoms was presented. Thus, additional follow up and management may be needed.
