The dizziness is obviously associated with a change in the position of the patient’s head and is considered to be caused by otoliths. Otolithiasis is also a very common clinical condition, with transient and recurrent attacks that occur in specific locations and last for a short period of time, because the otolith particles in the patient’s balance receptors are dislodged and when the head position changes, the otoliths irritate the cell membranes of the semicircular canals, leading to dizziness. If the patient’s head position is fixed, the symptoms of vertigo often end quickly. The most common type of otoliths belongs to the posterior semicircular canal, which usually occurs when the patient lies down or sits up flat on his or her back for a short period of time.
