- Abstract
- Objectives/Hypothesis: The present study aimed to evaluate the optimal reassessment time for treatment response in
posterior canal benign paroxysmal positional vertigo (PC-BPPV) following the initial Epley maneuver.
Study Design: Prospective, single-blinded, randomized study.
Methods: One hundred eight patients with PC-BPPV agreed to participate. These patients received a single modified Epley
maneuver (recommended by the 2008 American Academy of Otolaryngology–Head and Neck Surgery guidelines) daily until
positional nystagmus disappeared during the Dix-Hallpike maneuver 24 hours after the treatment. Repeated Dix-Hallpike testing
to reassess the treatment response was performed at 1 hour (post-1 hour), every 24 hours (post-24 hours) until the positional
nystagmus resolved, 1 week (post-1 week), and 1 month (post-1 month) following the therapeutic maneuver. The
difference in the resolution rates at post-1 hour and post-24 hours reassessment was analyzed, and the recurrence rates at
post-1 week and post-1 month were evaluated.
Results: The resolution rate was 67.6% at post-1 hour, which increased to 79.6% at post-24 hours reassessment. There
was a statistically significant difference in the results of the Dix-Hallpike test between post-1 hour and post-24 hours followup.
After complete resolution, nine out of 108 patients (8.3%) demonstrated recurrence within 1 month.
Conclusions: Reassessment after 24 hours following the initial Epley maneuver is more advantageous than a 1-hour
follow-up in patients with PC-BPPV. This information may be helpful for clinicians in deciding the appropriate follow-up period after treatment for PC-BPPV.
