Background: Bilateral vestibular dysfunction is a challenging condition that significantly impacts balance and overall quality of life. One of the causes of this dysfunction is benign paroxysmal positional vertigo (BPPV), which affects the inner ear and leads to episodes of dizziness. The Canalith Repositioning Maneuver (CRM) is a widely recognized treatment for BPPV in unilateral cases, but its effectiveness in bilateral vertigo remains less explored. This review aims to assess the current literature on the effectiveness of CRM in improving balance in patients with bilateral vertigo. Methods: A systematic review of studies was conducted using databases such as PubMed, Scopus, and Google Scholar. Inclusion criteria were studies that specifically addressed the use of CRM in patients with bilateral vertigo, examining outcomes related to balance, dizziness, and quality of life. Data was analyzed for trends in treatment success, adverse effects, and comparative effectiveness. Results: The review revealed that while CRM has shown significant effectiveness in managing unilateral BPPV, evidence for its success in bilateral vertigo is limited and inconclusive. A few studies indicated improvement in balance and reduction in dizziness after CRM, but these findings were often based on small sample sizes and varied methodologies. In some cases, patients experienced partial or temporary relief. Additionally, the effectiveness of CRM was found to depend on the specific type of vestibular dysfunction and the frequency of vertigo episodes. Conclusion: The Canalith Repositioning Maneuver may offer some benefit in patients with bilateral vertigo, but the evidence remains insufficient to draw definitive conclusions. Larger, well-designed clinical trials are needed to better understand its effectiveness and to establish specific guidelines for its application in this patient population. Until then, CRM should be considered on a case-by-case basis, with ongoing evaluation of its impact on balance and overall functionality.
