Otoliths are clinically known as benign paroxysmal positional vertigo, which is a brief paroxysmal attack of vertigo and nystagmus that occurs when the head moves rapidly to a specific head position, and is mostly caused by the dislodgement of an otolith that enters the semicircular canal. The otolith repositioning is the preferred treatment for this condition, and by “repositioning” I mean transferring the otolith floating in the semicircular canal. After otolith repositioning, patients need to pay attention to the following matters: sit still for at least half an hour after otolith repositioning to prevent the dislodged otoliths from falling out again; some patients may experience more intense vertigo or even vomiting after repositioning, so they also need to sit still for observation. If necessary, we can use vertigo stop or vomiting to relieve the symptoms after reset. However, it should be noted that otolithiasis is a disease that can easily recur, especially in the short term, because the otolith is still floating in the labyrinth of the inner ear and may re-enter the semicircular canal and cause symptoms. Some patients may still experience vertigo after treatment for otolith repositioning, either because the otolith has re-dislodged or because the function of maintaining balance has not yet been fully restored.
