Purpose: This present study was aimed at evaluating the effects of our original teaching method called “Bang Bang, Hu, Kacha” on the learning efficiency. Methods: We invented this method, which involves hand modulation and vocalization of words, for medical students to enable them to easily understand and memorize the anatomy of the inner ear and vestibular organs. We evaluated its effectiveness based on self-completed questionnaires by the students. Results: The results suggested that the comprehension level of the 30 medical students of the anatomy of the inner ear organs, especially the positional relationships of the semicircular canals and cochlea improved dramatically after they underwent training using this methodology. The medical students assigned high scores to this relational hand modulation method. Conclusion: This “Bang Bang, Hu, Kacha” method seemed to be a very useful for medical education, and allowed easy comprehension and memorization of the inner ear and vestibular anatomical structures.

Benign paroxysmal positional vertigo (BPPV) is the most common type of peripheral vertigo. BPPV occurs when calcium carbonate crystals (otoconia) in the utricle dislodge and migrate into the semicircular canals. There are two pathogeneses of BPPV: canalolithiasis and cupulolithiasis. Canalolithiasis involves to the presence of free cumulates of otoconia in the semicircular canals. When they become displaced in response to head movements, an endolymphatic flow is generated that abnormally stimulates the cupula, leading to vertigo. Cupulolithiasis involves a deposit of otolith nests that adhere to the cupula of the semicircular canal; thus, changing its specific gravity. Thus, the cupula is sensitized to linear accelerations, such as gravitational acceleration. The canalith repositioning procedure (CRP) is used to treat BPPV by moving the otoconia from the semicircular canal to the utricle. Although BPPV can resolve spontaneously, BPPV treated with CRP is resolved more quickly than untreated BPPV. In order to treat BPPV appropriately with the CRP, we must ensure its appropriate diagnosis.
