To determine whether vertigo is otolithiasis or not, the diagnosis is mainly confirmed by clinical symptoms, change of position test, audiological examination, vestibular function examination and imaging examination. 1. Clinical symptoms: recurrent short-lived vertigo or dizziness (usually lasting less than 1 minute) after changing the head position. 2. Position change test: During the examination, it is the head position in a specific position that induces the typical nystagmus and vertigo symptoms. 2. Audiological examination: Hearing in otolithiasis is usually not significantly abnormal, but may be abnormal if secondary to otogenic disease. 4. Vestibular function examination: mainly tracing the patient’s posture and analyzing the gait. 5. Imaging tests: such as CT or MRI, but not routinely performed. If you have frequent vertigo symptoms, it is likely to be otolithosis, you need to go to the hospital in time, cooperate with the doctor for examination and early treatment after diagnosis.
