vestibular function test

A method of examining the ear by special inspection. Basic Information Specialist classification: otolaryngology examination classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Stop taking central excitatory or inhibitory drugs 24 hours before the test, such as: stability, caffeine and so on. Coronary heart disease, severe hypertension, and cardiac insufficiency should be carefully examined; if it is older, it is best to have family members. Normal value normal. Clinical significance 1. Understand the functional status of the ocular system of the vestibular nervous system. 2. Identify vestibular and non-vestibular vertigo. 3. Identification of peripheral vestibular peripheral lesions. 4. Identification of the diseased side and normal side of peripheral vestibular lesions. Various vertigo syndromes. Precautions Most of the series of vestibular function tests are induced tests. The vestibular response is induced by appropriate stimulation (rotation, temperature change, displacement, etc.) of the vestibular peripheral receptor. According to the strength of the vestibular reaction (mainly nystagmus), presence or absence or Features are used to assess vestibular function. Because some patients with vertigo are sensitive to the vestibule, they may be accompanied by varying degrees of nausea or vomiting.

Coronary heart disease, severe hypertension, and cardiac insufficiency should be carefully examined; if it is older, it is best to have family members. Inspection process The structure and function of the vestibular system are complex. It is difficult to judge the function of a single item. Therefore, the EK and (posturogram) examinations can be performed. After the system examination, the vestibular function status is comprehensively judged. Not suitable for the crowd Generally there are no people who are not suitable. Adverse reactions and risks Generally no adverse reactions.
