Sound from the outside is transmitted to the human inner ear through two channels. One is the air conduction pathway through the external auditory canal, tympanic membrane, ossicular chain, and vestibular window, and the other is the bone conduction pathway where the movement and compression movement of the skull directly fluctuates the perilymph. When sound is transmitted into the inner ear, the hair cells on the basilar membrane of the cochlea undergo shearing movements to generate action potentials. The electrical signals are transmitted along the nerves to the brain to produce hearing. If any link in the above pathway is damaged, hearing will be affected. In medicine, hearing loss is generally referred to as deafness. Deafness does not mean that you cannot hear any sound, but it has a certain degree of difference. For example, it can be divided into mild, moderate and severe, or even complete deafness. Usually, we divide deafness into three categories: acoustic deafness, sensorineural deafness and mixed deafness according to the location of the disease: 1. Transmission deafness: refers to the obstruction of the sound transmission transformer device that affects the sound waves. Hearing loss caused by conduction. The sound conduction of the human ear is mainly air conduction, so hearing loss caused by lesions in the external auditory canal, tympanic membrane, ossicular chain and other structures are all conductive deafness. The lesions that can cause conductive deafness mainly include the following conditions: ( 1) Cerumen embolism (2) Tympanic membrane perforation (3) Tympanic membrane invagination (4) Secretory otitis media (5) Suppurative otitis media (6) Ossicular chain interruption (7) Tympanosclerosis 2. Sensorineural deafness: Yes It means that the lesions are located in the hair cells of the ear spiral organ, the auditory nerve and the auditory centers at all levels, causing obstacles to sound perception and nerve impulse conduction, causing sensorineural deafness. Common diseases are as follows: 1) Otosclerosis 2) Meniere's disease (3) Congenital deafness (5) Deafness caused by infectious diseases (6) Deafness caused by some other diseases in the body: hypertension and arteriosclerosis are the most common. See. The cause is an obstruction in the nutrient and blood supply to the inner ear. Others such as diabetes and hypothyroidism can also cause hearing loss. (7) Drug poisoning deafness (8) Traumatic deafness 9) Sudden deafness There is currently no single, specific and effective treatment for this. The treatment of tinnitus usually requires the use of two or more treatments at the same time, and the treatment needs to be for a long period of time, so as to receive a more satisfactory treatment effect. 1. Tinnitus masking 3. Biofeedback is a relaxation technique that allows patients to control certain autonomous body functions, such as pulse, muscle tension, and brain wave activity. Its purpose is to allow patients to improve their ability to adapt to life activities. 4． Cognitive therapy changes the patient's perception of tinnitus, and can be very effective when combined with masking or drug treatment. 5． Medications: Anti-anxiety drugs, such as alprazolam; antidepressants, such as nortriptyline; antihistamines; anticonvulsants, and even narcotics, such as lidocaine, can all be used to treat tinnitus with certain results. Dexamethasone injection into the middle ear also has good effects on patients with tinnitus, hearing loss, and vertigo. 6. Tinnitus retraining treatment gives the affected ear a low-loud, stable background sound for 8 hours a day, allowing the patient to gradually become familiar with the sound of his or her tinnitus. This method should last 1 to 2 years. There are also acupuncture, hyperbaric oxygen, electrical stimulation, surgery, cochlear implant treatment, etc. These treatments need to be carried out selectively under the guidance of a doctor.
