Vertigo is a common clinical condition. About 50% of the patients with clinical vertigo are cervical vertigo. Foreign clinical data also show that more than 50% of patients in ENT are related to cervical spondylosis. It can be seen that vertigo is closely related to cervical spondylosis. Cervical vertigo. As the name implies, the vertigo is related to the neck. It often occurs when the neck is moving, especially when the head is turned or the neck is flexed excessively, and the patient feels that the surrounding scenery or himself rotates, or goes up and down, or shakes from side to side, or has the feeling of moving. Some patients have vomiting, sweating and other symptoms along with vertigo. In mild cases, the vertigo can be cured in a few seconds, but in severe cases, the vertigo may last for several days or more before it gradually subsides. The main mechanism of cervical vertigo is believed to be: insufficient blood supply to the basilar artery and cervical sympathetic hyperactivity. Due to the internal and external factors such as micro dislocation of cervical vertebrae, osteophytes and abnormalities of cervical muscles, the vertebral artery is compressed directly or indirectly, or the sympathetic nerves around it are stimulated, causing the vertebral artery to contract and narrow its lumen, resulting in insufficient blood supply. This eventually leads to vestibular vagus ischemia and vertigo symptoms. Among the clinical manifestations of cervical vertigo, vertigo is the most prominent symptom, with a sense of rotation, floating, disorientation, and dizziness, etc. It mostly occurs when the head and neck position is changed, such as turning back and turning the neck, getting up and lying down, stretching and flexing the neck, etc. The attack time may be instantaneous and last for a few seconds, or even up to a day or even several days, and the symptoms are mostly migraine, accompanied by nausea, vomiting, chest tightness, panic, abnormal sweating and other symptoms. Most people also have neck stiffness and limited movement. In addition, it is often accompanied by tinnitus, hearing loss, nasal congestion, sore throat, foreign body sensation in the throat, voice changes, and blurred vision. The auxiliary diagnosis of cervical vertigo mainly includes X-ray, CT, MIR, cerebral hemogram, cervical cranial Doppler ultrasound, blood rheology examination and so on. The key to diagnosis is to exclude other causes of vertigo, especially otogenic and oculogenic vertigo, and if necessary, to ask relevant specialists to assist in the diagnosis. Prevention of cervical vertigo: 1. Move your neck more often, especially for middle-aged and elderly people. You should move your neck from all directions several times a day. 2.Try not to twist your neck suddenly and not to tilt your head too long. 3.When it is cold, you should pay attention to the warmth of the neck, because the cold neck is also one of the triggering factors of vertigo. 4.Cervical spondylosis is also related to osteoporosis, so you should drink milk often, get sunlight, and take calcium supplements if necessary. The height of the pillow should be the height from the ear to the outer edge of the shoulder on the same side, that is, when lying on the side, the inherent position of the neck should be maintained without tilting.
