AI Technical Summary
Traditional semicircular canal models have a unique structure, making it difficult for patients to understand their relationship with the angle of the human head. They also cannot clearly understand the movement principle of otolith particles inside the semicircular canals through model rotation, which affects their understanding of the treatment process for benign paroxysmal positional vertigo (BPPV).
A three-dimensional model of the semicircular canals in otolithiasis was designed. By fixing a simulated semicircular canal model onto a simulated head model, and filling the model with glycerol solution to simulate endolymph, the movement trajectory of the otolith lens in the endolymph can be observed by rotating the model. Combined with the support structure of the scaffold, the rotation of the model is made more stable and the angle can be adjusted precisely.
This allows patients to better understand the treatment process for benign paroxysmal positional vertigo (BPPV). The rotating model visually demonstrates the movement of otolith particles within the semicircular canals, improving the comprehensibility of the treatment process and the fluency of the demonstration.
