Machine repositioning for otolithiasis requires a decision on how many repositions to perform depending on the patient’s symptoms. In mild cases of otolithiasis, most of the time the vertigo disappears with 1-2 repositionings. In patients with recurring symptoms, multiple repositionings may be required until the symptoms are completely resolved. Some patients may be able to achieve successful repositioning with a single repositioning, so there is no such thing as the best number of repositionings for otolithiasis. The disease is self-limiting and has the potential to heal itself even without treatment. After the machine reset is successful, there is no guarantee that the otolith will not fall out again and cause the symptoms to recur. Therefore, the number of times to reset the otoliths depends on the disappearance of the symptoms and whether the symptoms recur or not, and it can be treated under the guidance of the doctor.
