Dizziness and headache are common clinical symptoms, but unlike most diseases that cause headaches that cannot be cured, there is a specific group of dizziness patients for whom the disease that causes their symptoms to flare up is curable. This disease is often mistaken by patients and even some clinicians as cervical spondylosis, air conditioning disease, Meniere’s disease, cerebral blood supply deficiency, etc., but in fact it is a special disease called benign positional vertigo (BPPV), commonly known as otoliths, which accounts for 17-52.5% of the diseases causing vertigo and is more common in women, and its main clinical manifestation is recurrent episodes of transient vertigo, associated with head position changes, accompanied by In BPPV, in addition to transient vertigo, patients may experience a sense of levitation, tilting, falling, rotation, tilting or shaking of visual objects, cold sweat, panic, nausea and vomiting. The human inner ear consists of the hearing organ and the hemianopia, which controls the sensation of variable speed movements. Small stones can develop in the semicircular canal as a result of head trauma, previous Meniere’s disease, vestibular neuritis, history of osteoporosis, oral calcium tablets, or even for unknown reasons. These stones can be dislodged and rolled in the semicircular canal as the position of the body or head changes, causing vertigo immediately or for an extreme period of time. When the position changes stop, the otoliths are fixed and the vertigo disappears for a short period of time; it reappears with a resurgence of motion. Therefore, the vertigo attacks in BPPV patients are characterized by 5 major features: episodic, transient, variable position, latency and fatigue. BPPV can be cured. Patients who are suspected of having BPPV need to be seen in a timely manner, and the doctor will give a special evoked test according to the condition, and according to the patient’s special nystagmus in different special positions, the doctor will determine which semicircular canal produces the otolith dislodgement roll. Based on this judgment, the patient is then given special manipulation to turn the patient’s body and head, which eventually causes the otolith to return to its original position and become embedded, significantly improving the onset of symptoms. However, on the other hand, manipulation can cause a recurrence rate in patients with BPPV, as the otolith can be dislodged and rolled again. In 1 year of treatment, 7-23% of patients will relapse, 50% of patients will relapse in the long term, leaving 50% of patients i.e. cured for life. Thankfully, patients who relapse can still significantly improve their symptomatic episodes after being treated again with manual repositioning.
