Benign positional vertigo, a benign paroxysmal positional vertigo, commonly known as otolithiasis, may be due to degenerative changes in the elderly, trauma, exercise, ear disease, and inadequate blood supply to the inner ear.
1. Degenerative changes in the elderly: aging of the labyrinth of unknown etiology, otoliths deposited in the semicircular canals due to spontaneous degeneration of the ellipsoid cysticercus and the globus pallidus.
2. Trauma, sports: head trauma or accelerated head movement, resulting in otoliths dislodged into the semicircular canals.
3. Ear diseases, such as Meniere’s disease, vestibular neuritis, chronic suppurative otitis media, etc., caused by otoliths dislodged in the semicircular canals.
4. Insufficient blood supply to the brain: arteriosclerosis, hypertension, etc. cause insufficient blood supply to the brain, resulting in otoliths dislodged into the semicircular canals can induce benign positional vertigo, which can lead to benign paroxysmal positional vertigo.
Benign paroxysmal positional vertigo requires timely consultation and reset treatment.
