The Yacovino maneuver was seen to be an effective treatment option for ac-BPPV without having to determine the side involved. Results: The simulation showed that the supine head-hanging test is a good test for diagnosis of ac-BPPV affecting both labyrinths and demonstrated why there is no inversion of nystagmus on sitting up. Three repositioning maneuvers were simulated: 1) the Yacovino maneuver and its modifications, 2) the reverse Epley maneuver and 3) the short canal repositioning (CRP) maneuver. Simulations of the supine head-hanging test for diagnosis of ac-BPPV were studied. Methods: Based on reconstructed MRI images and fluid dynamics, a 3D dynamic simulation model (as a function of time) was developed and applied. This can help to optimize existing treatment maneuvers and help in the development of better management protocols. The aim of this study was to use three-dimensional simulation models to visualize otoconial debris movement within the anterior canal during diagnostic tests and different liberatory maneuvers. Various diagnostic and therapeutic maneuvers have been described for its management.
