If you have tinnitus (persistent low-key sounds, such as wind, thunder, machine sounds, etc. While others hear high-profile sounds, such as whistles, birds singing and cicadas singing. , some still hear a short plane sound), it can still be treated. If it doesn't ring, there is little hope of cure. I learned all this from the doctor when I was in the hospital. If your illness is like this, you can look at the following introduction.
The cause of tinnitus is very complicated. Traditional Chinese medicine often interprets it as the appearance of kidney deficiency, and excessive fatigue can also produce tinnitus. Western medicine mainly explains from pathology, psychology and ear reflex.
Pathology: Some people's tinnitus is caused by ear diseases or diseases in other parts of the human body. Under normal circumstances, all kinds of noises in the human body are not easily detected by the human ear, because the sound waves from the external sound field cover the internal sound waves, and at the same time, the eardrum, ear bones and ligaments of the human ear have the function of dispersing the internal sound waves to the external auditory canal. Ear diseases, such as external auditory canal obstruction, increased inner ear pressure, etc. Patients are prone to tinnitus. In addition, heart and lung diseases, hypertension, drug allergy and other reasons will increase the noise in the body, exceeding the conventional value, leading to tinnitus.
Psychological aspect: attention is drawn away from the outside world, but concentrated on proprioception, which sometimes weakens the adaptability of hearing and leads to tinnitus. Due to the concentration of attention, tinnitus will be strengthened, and the feeling of tinnitus will also be strengthened.
Earwax: Some people's tinnitus is caused by earwax. The ear is the organ that receives sound, but modern medicine finds that the ear can also emit sound waves.
1948 T.Gdd predicts that it is possible to record sound waves corresponding to tinnitus in the external auditory canal of tinnitus patients. 1978, D.T. Kemp successfully recorded the sound waves emitted by human ears for the first time. The AE frequency of ears is in the range of 1-3kHz, and the intensity is generally less than 20dB. The AE frequency and intensity of ears may be different. Therefore, people who emit acoustic emissions will hear high-pitched noise with a long or short duration in a quiet environment, and at the same time will cause certain hearing loss.
At present, there is no conclusion about the emission principle of the ear. At present, it is generally believed that it may be the product of spontaneous mechanical oscillation of the highly tuned component (basement membrane) in the cochlea, and the exciting substance may be thermal exercise or metabolic exercise. Under the sudden strong sound stimulation, normal human ears will also produce acoustic emission, which is called evoked acoustic emission. The frequency of evoked acoustic emission is similar to the pronunciation source, and its intensity depends on the stimulus, generally between 30-50dB. Thunder nearby will make people feel rumbling in their ears.
The acoustic emission of the ear is considered as a kind of tinnitus, which is called objective tinnitus. Ordinary tinnitus has no acoustic emission phenomenon.
Tinnitus is the subjective feeling of sound in patients' ears or heads, which is caused by hearing impairment. Deafness or dizziness caused by ear lesions often coexist. If it is caused by other factors, it may not be accompanied by deafness or dizziness.
Tinnitus caused by ear diseases is called otogenic tinnitus. It is usually low, such as the roar of the wind, trains or machines. It may also be a treble, such as cicada, whistle or whistle. External auditory canal diseases, such as cerumen, foreign body, tumor, mycosis, or inflammatory swelling, can all cause tinnitus, and its severity is related to the degree of blockage. In middle ear diseases, a few patients with chronic otitis media may have tinnitus, but the degree is slight. Negative tympanic pressure, ossicular chain adhesion or fixation can all cause tinnitus. Otosclerosis tinnitus is more obvious, which starts with intermittent low tone, and then gradually increases, which can be transformed into persistence. Such a patient is very painful. Tinnitus caused by inner ear diseases is mostly intermittent or persistent. The degree of tinnitus is often related to the scope and degree of the lesion. In the damage of drugs to auditory nerve, tinnitus often appears earlier than deafness. In the degradation of sensory system in the elderly, tinnitus is often a precursor to deafness. The low-frequency tinnitus of inner ear vertigo (Meniere's syndrome) often appears before the onset of vertigo, but it can also coexist with vertigo and deafness. After the dizziness is relieved, tinnitus gradually reduces or disappears. Noisy tinnitus is often high-pitched, and the course of disease is mostly persistent tinnitus.
In addition to ear diseases, emotional excitement, anxiety and mental stress can also induce tinnitus. Traditional Chinese medicine theory holds that tinnitus and deafness are often caused by kidney deficiency. And there are amnesia, dreaminess, palpitation and other symptoms, which can be gradually improved after strengthening the body resistance and tonifying the kidney.
Tinnitus caused by pathological changes of blood circulation system is not uncommon, while tinnitus from veins is noisy. The tinnitus produced by the artery is often consistent with the heartbeat. Tinnitus caused by hypertension is generally bilateral. Carotid body tumor tinnitus is unilateral. Arteriosclerosis, heart valve diseases, etc. It can also cause pulsating tinnitus. When tensor tympani and stapedius muscle contract strongly, intermittent "kata" sound can be made. Similar tinnitus may also be caused by clonus of pharyngeal muscle or palatine muscle.
Tinnitus should be distinguished from auditory hallucination. Auditory hallucination is a mental symptom, which tells you that you can hear some complicated sounds, such as "speaking voice", "swearing voice" or "playing music". It's completely different from monotonous tinnitus.
Tinnitus makes people upset and fidgety. When it is serious, it will affect their lives and work. Most patients with persistent tinnitus can get used to it for a long time.
Once tinnitus occurs, we should actively treat it according to the cause, comfort and explain the patient more and eliminate doubts. Seriously ill patients can take sedatives. In addition, you can wear a hearing aid or a tinnitus mask, that is, use external sounds to cover up your tinnitus, and the condition can be gradually alleviated.
