Summary

Benign paroxysmal positional vertigo (BPPV) treatment success depends on the affected semicircular canal. BPPV not in the posterior canal often requires multiple canalith repositioning visits.

Area of Science:

  • Neurology
  • Otolaryngology
  • Vestibular Rehabilitation

Background:

  • Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo.
  • Canalith repositioning maneuvers are a primary treatment for BPPV.
  • Predicting treatment outcomes can optimize patient management.

Purpose of the Study:

  • To identify factors influencing treatment outcomes in BPPV patients.
  • To determine variables affecting the number of canalith repositioning visits required.

Main Methods:

  • Retrospective review of 259 BPPV patients treated at a tertiary vestibular rehabilitation center.
  • Analysis of variables including diagnosis method, age, sex, trauma history, canal involvement, bilateral disease, and treatment details.
  • Multivariate statistical analysis using chi-squared, likelihood ratio, and cross-tabulation tests.

Main Results:

  • 98.4% of patients achieved symptom relief after three treatment visits.
  • Bilateral disease or involvement of canals other than the posterior semicircular canal significantly increased the number of required treatment visits.
  • Patient age, sex, diagnosis method, and trauma association did not significantly impact treatment outcomes.

Conclusions:

  • Canalith repositioning is highly effective for BPPV.
  • Location of BPPV outside the posterior semicircular canal is a key predictor for requiring multiple treatment sessions.
  • Treatment protocols may need adjustment for complex BPPV presentations.
