Mixed tinnitus?

summary

Mixed tinnitus is not very common, and we know very little about it. Mixed tinnitus refers to the tinnitus caused by the simultaneous involvement of auditory and sensory systems. There are similarities and differences in the causes of otoacoustic and sensorial system damage. Mixed tinnitus? Let's talk about it.

Mixed tinnitus?

One, two parts of the damage caused by different causes of mixed tinnitus common, such as otitis media, presbycusis, noise deafness or tinnitus caused by systemic diseases.

2、 The reasons for the damage of the two parts can be the same or different. For example, on the basis of conductive hearing loss caused by suppurative otitis media, labyrinthitis or solid bacterial toxins, ototoxins, etc. infiltrate into the inner ear through the cochlear window membrane, causing the physical and chemical properties of labyrinth fluid and structural changes of stria vascularis and spirochete organ, resulting in secondary sensorineural hearing loss.

3、 Long term noise exposure: the strongest sound that the human ear can bear is usually 90 dB. If it exceeds this limit, even if it can't feel it, the fragile and sensitive inner ear has been damaged. Irregular and strong stimulating noise is more harmful to hearing. The sound intensity of singing hall, disco and recreation hall often exceeds 115 dB, and tinnitus is easy to occur in such environment.

matters needing attention

1. It is necessary to be careful to use or prohibit the things that damage the auditory nerve. Aminoglycoside antibiotics are the most common ototoxic agents causing cochlear damage. Therefore, it is an important measure to avoid the abuse of aminoglycoside antibiotics to reduce physical deafness. The family with a history of ototoxicity allergy should be more careful with this kind of material. 2. Avoid exposure to high decibel noise for a long time. Exposure to high decibel noise for a long time will damage the hair cells and inner ear, resulting in noise induced deafness. Factory noise can lead to occupational noise induced deafness. Karaoke and other noisy entertainment places should not go as far as possible. In addition, long time listening to earplugs should be avoided, otherwise hearing loss will be caused. 3. Massage your ears often. Massage can promote blood circulation of inner ear, such as massage auricle, knead earlobe, massage Fengchi acupoint on both sides of hairline after neck. You can also sit quietly with your eyes closed, insert your two index fingers into the two ear holes, and then quickly pull them out. Do this 10 times in a row. 4. Develop scientific eating habits. Eating more food rich in zinc, iron and calcium can reduce the lack of trace elements, which helps to expand the microvascular, improve the blood supply of the inner ear and prevent hearing loss. Don't take out your ears. If the force is not appropriate, it is easy to cause external auditory canal injury and infection, leading to external auditory canal furuncle, inflammation and ulceration. If you don't pay attention when you pull out the ear, the ear scoop will also damage the tympanic membrane or auditory ossicles, causing perforation of the tympanic membrane and affecting hearing. 6. We should actively treat hypertension, hyperlipidemia, cerebral arteriosclerosis, diabetes and other diseases. These diseases may cause ear lesions. 7. Be careful to use or prohibit the substances that damage the auditory nerve: aminoglycoside antibiotics are one of the ototoxic substances that cause the most damage to the cochlea. Therefore, avoiding the abuse of these antibiotics is an important measure to reduce physical deafness. The family with a history of ototoxicity allergy should be more careful with this kind of material. 8. Maintain a good mental state: when people are emotional or anxious, the secretion of adrenaline increases, which can cause spasm in the small arteries of the inner ear, slow blood flow in the small vessels, resulting in insufficient oxygen supply to the inner ear, leading to sudden deafness.
