The medical term for “otoliths” is “benign paroxysmal positional vertigo”. When the otoliths are dislodged by some factors, they float in the inner ear like sand and dust, and when they float in a specific position, they may cause vertigo when there is a change in position. This is “benign paroxysmal positional vertigo”. Since the otolith is dislodged, the only way to get better is to find a way to return it to its original position, otherwise you won’t be able to take a train of medicine! Therefore, manual repositioning treatment is the preferred treatment for patients with otoliths. The main symptoms of “benign paroxysmal positional vertigo” are: transient rotational vertigo that occurs when the patient’s head moves rapidly to a certain position. The most common complaint is vertigo when sitting up in bed, lying down, turning from side to side in bed, bending over or looking up. The disease is most common in middle-aged patients and may be associated with the following factors or secondary to the following diseases: (1) otolithiasis: occurs when the otolith membrane is dislodged into the semicircular canal and deposited there after age-related degenerative changes; (2) trauma: otoliths may be dislodged into the semicircular canal after cranial trauma or accelerated head movements; (3) ear diseases: middle ear mastoid infections such as viral labyrinthitis, chronic suppurative otitis media, external (4) Inadequate blood supply to the inner ear: Inadequate blood supply to the inner ear due to atherosclerosis and hypertension, which may lead to thinning of the colloid membrane of the capsule and dislodging of the otolith into the semicircular canal. Otoliths are one of the most common diseases of peripheral vertigo, and many non-neurologists may think that it is cervical spondylosis or attribute it to posterior circulation ischemia, and delay treatment. In fact, otoliths can sometimes be improved with just one or two manipulation resets. Of course, I have had a patient who had 8 resets before complete relief, but otoliths, if misdiagnosed, cannot lead to life-threatening pain, but the pain it causes is obvious. What is described here is one of the methods of self-repositioning (otolith). 1. First, sit on the bed in an upright position; 2. Lie on your side and after 1-2 seconds, turn your head and keep it at a 45 degree angle (method: imagine someone standing in front of you about 2 meters and then you keep looking at his head). Hold this position for 30 seconds, or until your dizziness disappears; 3. Return to the upper body upright position and hold it for 30 seconds; 4. Lie on your side to the other side. Again, after 1-2 seconds, turn your head and hold it at a 45 degree angle (45 degrees in the other direction). Hold this position for 30 seconds, or until your dizziness disappears; 5. Go to the upright position again and wait 30 seconds.
