Research on the Integrated Repositioning Method for Benign Paroxysmal Positional Vertigo

Objective: This study aims to investigate an integrated repositioning technique for treating benign paroxysmal positional vertigo (BPPV).Methods: We utilized three-dimensional CT scans of the inner ear to extract the structure of the semicircular canals. Using 3D printing technology, molds were created to simulate the repositioning of otoliths within these canals. These molds were then integrated into a wearable headgear device that allows for real-time simulation and demonstration of the movement trajectories of otoliths during repositioning.Results: Demonstrations with the molds confirmed that repositioning of otoliths could be effectively achieved simultaneously in both canals.Conclusion: The repositioning method effectively addresses the simultaneous repositioning of dislodged otoliths in the posterior and horizontal canals on a single side. This method facilitates otolith repositioning in all four semicircular canals, whether performed on the left or right side.
