Abstrakt: Purpose: This study introduces and evaluates the sitting lateral canal maneuver (SLCM), a novel seated repositioning technique for treating geotropic lateral canal benign paroxysmal positional vertigo (BPPV).
Methods: We conducted a retrospective chart review at the Hospital of Salerno, focusing on 26 patients diagnosed with geotropic LC-BPPV between 2021 and 2022. The SLCM was applied, and its efficacy was assessed based on the resolution of nystagmus and vertigo symptoms. A 95% confidence interval was calculated to estimate the success rate.
Results: The SLCM demonstrated a high success rate, with 22 out of 26 patients (approximately 85%, 22/26 patients) showing positive outcomes. The 95% confidence interval for the success rate ranged from approximately 65.02-100%. These findings suggest that SLCM is a potentially effective intervention for LC-BPPV, especially beneficial for patients who find traditional supine or lateral maneuvers uncomfortable.
Conclusion: The SLCM represents a promising alternative to traditional BPPV maneuvers, especially for patients requiring a seated approach. While the initial results are encouraging, further research with larger sample sizes and longer follow-up periods is needed to validate its efficacy and explore its full potential in the management of LC-BPPV.
Level of Evidence: This study represents a Level IV source of evidence, as defined by the evidence-based practice guidelines. It is a retrospective chart review that involves a moderate cohort of patients diagnosed with geotropic horizontal positional nystagmus consistent with lateral canal benign paroxysmal positional vertigo (LC-BPPV). While the study provides valuable insights into the efficacy of the sitting lateral canal maneuver (SLCM) and contributes to the existing literature on BPPV management, it is important to note the inherent limitations associated with this level of evidence.
