Dizziness is a dynamic or positional illusion caused by the body’s obstacle to spatial localization. It involves multiple disciplines. Most people experience this disease throughout their lives.
According to statistics, vertigo accounts for 5% of medical outpatients and 15% of Otorhinolaryngology clinics. Dizziness can be divided into true vertigo and pseudo vertigo. True vertigo is caused by diseases of the eye, the body or the vestibular system, and has obvious foreign objects or a sense of rotation. False vertigo is caused by systemic diseases, such as cardiovascular disease, cerebrovascular disease, anemia, uremia, drug poisoning, endocrine diseases and neurosis. There are almost dizziness symptoms, and patients feel “floating.” Swing”, there is no clear sense of rotation. The following is mainly for the vertigo of otolaryngology.
The vertigo caused by the inner ear labyrinth or the vestibular part and the extracranial segment of the vestibular nerve (in the internal auditory canal) is peripheral vertigo, including acute labyrinthitis and Meniere’s disease.
Its characteristics are: 1 vertigo is severe rotation, short duration, head position or body position change can make vertigo increase significantly. 2 nystagmus: nystagmus and vertigo attacks exist simultaneously, mostly horizontal or horizontal plus rotatory nystagmus. 3 balance obstacles: mostly rotatory or up and down and left and right swinging movement sense, standing unstable, spontaneous dumping, static upright test multi-directional nystagmus slow phase dumping. 4 autonomic symptoms: such as nausea, vomiting, sweating and pale. 5 often accompanied by tinnitus, hearing impairment, and no brain damage.

The onset is sudden and begins to be persistent vertigo. After a few days, it is relieved and turned into paroxysmal vertigo. However, dizziness occurs when the head is in a certain position, which lasts for several tens of seconds, and vertigo can be reduced or disappeared when turning or reversing the head position. Significant nystagmus is visible, and the duration of vertigo varies greatly.

At the beginning, the vertigo reaches the most serious degree. The head activity and the blinking are intensified. It is often accompanied by dumping.
