Dizziness after otolith repositioning may be due to unsuccessful otolith repositioning or recurrence of otolith, incomplete recovery of vestibular function, and other undiagnosed diseases that cause vertigo. 1. Unsuccessful repositioning of otolith or recurrence of otolith: Otolithiasis is mainly caused by the dislodgement of otoliths from the semicircular canals, which stimulates the endolymphatic fluid and leads to vertigo symptoms. Otoliths are prone to recurrence, and some patients may not be successful in one repositioning and need multiple repositionings. Therefore, if you still have vertigo after repositioning, it is recommended that you have a second consultation and if necessary, you need to reposition the otolith several times. 2. Vestibular function is not fully restored: After the otolith is reset, the vestibular organ function is not restored immediately, so there are still symptoms of dizziness. Vestibular function can be adjusted through vestibular inhibitors or vestibular rehabilitation training. 3. Other diseases causing vertigo undiagnosed: there are many other diseases causing vertigo, if there are still symptoms of vertigo after otolith reset, you need to be alert to other undiagnosed diseases, it is recommended to go to the hospital in a timely manner for follow-up, symptomatic treatment. If you still have vertigo after otolith repositioning, it is recommended to go to the hospital as soon as possible for further examination and targeted treatment by a specialist.
