First of all, it is important to clarify that tinnitus is a symptom, not a specific disease. That is, tinnitus is a common symptom of many diseases. What is tinnitus? Tinnitus is the subjective sensation of sound, mostly a single pure tone, in the absence of a corresponding external sound source or stimulus. This type of tinnitus is called subjective tinnitus, or autosensory tinnitus, which cannot be heard by others. There is another kind of tinnitus, called other-perceived tinnitus, or objective tinnitus, that is, tinnitus that can be heard by others at the same time. In diseases such as palatal muscle spasm, stapedius muscle spasm, tympanic membrane tensor spasm, temporomandibular joint disease and eustachian tube constant field opening, the examiner can often hear the ringing at the same time with the patient. Most often it is not a sustained single frequency. If speech-like tinnitus is heard, such as bitter laughter, cursing, or talking, this is not considered tinnitus; it is called phantom hearing. It is not a disease of the ear. The causes of tinnitus can be basically divided into two categories: otogenic and non-otogenic. The former refers to tinnitus caused by ear diseases, while the latter refers to tinnitus caused by physical diseases other than ear diseases. Tinnitus of otogenic origin can be caused by disease in any part of the ear, from the outer ear to the middle ear to the inner ear. The main factors affecting tinnitus, the causes of tinnitus are very many and complex. Common factors are: 1. Psychological factors: sudden mental stimulation from unexpected events, depression, depression overwhelming apprehension, mood swings and other psychological disorders can produce tinnitus; 2. Noise: being in a noisy environment for a long time can often lead to tinnitus; 3. Endocrine endocrine disruption: such as women’s menstrual period during pregnancy, can produce tinnitus. In recent years, the number of women with tinnitus during menopause has increased significantly; 4. Diet and alcohol and tobacco. People with high cholesterol, high fat and high salt diet have significantly higher incidence and severity of tinnitus than those with normal diet, which may be related to their susceptibility to diabetes and hypertension. Some patients with food allergies also have a much higher incidence than those on a normal diet. Excessive smoking is significantly more prone to tinnitus, which is related to the effect of nicotine on blood vessel function. It is important to mention that psychological factors are crucial to the impact of tinnitus. If you are optimistic and happy, you will not only have less tinnitus, but also recover easily. On the contrary, those who are sad, depressed, angry, tense and anxious are not only prone to tinnitus, but also have poor treatment results. Basic principles of treatment: 1. Minimize or eliminate the factors that cause tinnitus, such as systemic and ear diseases; 2. Give oral or intravenous drugs to unblock blood vessels, improve circulation and nourish nerves; 3.
