Can’t hear well after coming down from the mountain?

Many people like to climb mountains, and they will make plans with friends to go hiking on weekends. However, accidents can easily happen when climbing mountains. Some people accidentally roll down the mountain. Most of them are not serious, but some people have short-term tinnitus. In this case, you must pay attention to rest more. Generally, you will recover after a while, but if you cannot recover for a long time, it is best to go to the hospital for examination as soon as possible.

There are four main reasons for the rapid increase in the number of patients with sudden deafness:

First of all, modern people generally have an irregular lifestyle. Most people are overly tired and stay up late to surf the Internet, which leads to a decrease in the immune function of the ears. Listening to cold wind through headphones will lead to the invasion of wind and cold evils, so it is not surprising that sudden deafness occurs.

The second is the increase in urban "noise pollution". Many sounds that the human ear does not notice, including low-frequency noise from computers and many electronic devices, can cause damage to human hearing at any time.

Third, due to excessive mental stress, for example, pressure from study and work, many college entrance examination students and their parents may even suffer from sudden deafness.

Fourth, psychological factors stimulate many patients. They work overtime until late the night before the onset of the disease, and their boss rejects their own copywriting. The next day they start to feel dizzy, and after a few days they gradually develop tinnitus or even deafness.

7 major reasons may cause deafness

(1) Infectious disease-induced deafness: Various acute infectious diseases, bacterial or viral infections, such as epidemic encephalitis B, mumps, purulent meningitis, measles, scarlet fever, influenza, herpes zoster oticus, typhoid fever, etc. can damage the inner ear and cause sensorineural deafness of varying degrees.

(2) Drug-induced deafness: It is common in aminoglycoside antibiotics, which can cause sensorineural deafness. Ear drug poisoning is closely related to the body's susceptibility. Drug-induced deafness is bilateral, often accompanied by tinnitus, and vestibular function may also be impaired. Long-term use of such drugs in the middle ear may also penetrate into the inner ear through the cochlear window membrane, so this should be noted.

(3) Presbycusis: It is mostly caused by vascular sclerosis and bone hyperplasia in the elderly, which leads to insufficient blood supply to the spiral hair cells and spiral ganglia, degenerative lesions, or decline of the central nervous system, resulting in hearing loss.

(4) Traumatic deafness: Craniocerebral trauma and temporal bone fractures damage the inner ear structure, leading to inner ear bleeding, or inner ear damage caused by strong concussion, all of which can lead to sensorineural deafness, sometimes accompanied by tinnitus and vertigo. Accidental damage to the inner ear structure during ear surgery can also lead to deafness.

(5) Sudden deafness: It is a type of sensorineural deafness that occurs suddenly and the cause is unknown. It is currently believed that acute vascular obstruction and viral infection are common causes of this disease. Deafness can appear in an instant or reach a peak quickly within hours or days. It is mostly unilateral but may also affect both ears, accompanied by tinnitus and sometimes vertigo. Early treatment can achieve better results.

(6) Noise-induced hearing loss: A slowly progressive sensorineural hearing loss caused by long-term exposure to noise levels above 85 dB (A). The degree of deafness is mainly related to noise intensity and exposure time, and secondly to noise spectrum and individual differences. Some people have found that noise of 2000Hz to 4000Hz is most likely to cause cochlear damage.

(7) Blast-induced hearing loss: acute hearing damage caused by sudden strong pressure waves and strong pulse noise. The eardrum and cochlea are the parts of the hearing organ that are most vulnerable to damage. When people are exposed to noise above 90dB (A), cochlear damage may occur. If the intensity exceeds 120dB, permanent deafness may occur. The degree of deafness is related to noise intensity, number of exposures, peak value, pulse width, spectrum, individual differences and other factors of the pressure wave. The nature of deafness is mostly sensorineural or mixed.
