How is mixed deafness diagnosed?

If young people occasionally experience short-term tinnitus, but it will return to normal soon, this is likely to be caused by sudden noise stimulation of the ears, or caused by work stress, pressure, insomnia and other reasons. Pay attention to your daily life and use of your ears. It will be relieved if you get used to it; if tinnitus persists for 1-2 days, you must go to the hospital for examination. Don’t take it seriously because it is just tinnitus and does not affect your hearing, because some high-frequency deafness is just tinnitus at first and your hearing is not affected, but over time, deafness will suddenly appear.

How to identify mixed deafness?
Deafness is common, and there are many types of deafness. No matter which type it is, it will bring harm to the patient, causing hearing loss or even hearing loss.
Distinguishing between conductive hearing loss and nerve deafness:
Conductive hearing loss: Hearing impairment caused by lesions of the outer ear or middle ear is called conductive deafness.
Nervous deafness: Nervous deafness refers to a disease that occurs in the auditory nerve of the inner ear and the auditory center of the brain, causing hearing loss or even hearing loss. It is often accompanied by tinnitus.
The medical history should be carefully inquired, the external auditory canal and tympanic membrane should be examined, and tuning fork examination and pure tone audiometry should be performed to determine the nature and degree of deafness. For children and uncooperative adults, objective listening can also be performed.

It can be divided into three categories according to the location and nature of the disease:
(1) Conductive deafness: a disease occurs when the sound transmission mechanism of the outer ear and middle ear causes sound waves to pass into the inner ear. Deafness caused by disorders such as cerumen embolism, otitis media, etc.
(2) Sensorineural hearing loss: refers to the cochlear spiral organ disease that cannot convert sound waves into nerve excitement, or the nerves and their central pathways are blocked from transmitting nerve excitement; or the cerebral cortex center lesions cannot distinguish language, collectively referred to as sensory hearing loss. Sone nerve deafness such as Meniere's disease, ear drug poisoning, labyrinth, noise damage, acoustic neuroma, etc.
(3) Mixed deafness: There are lesions in both the sound transmission and sensor mechanisms, such as long-term chronic suppurative otitis media, otosclerosis, late blast deafness, etc.

The symptoms of mixed deafness may include the following points:

The symptoms of mixed tinnitus generally include high-pitched and intractable tinnitus. At the beginning, it is an intermittent sharp sound, sometimes occurring first in one ear, and gradually develops into a continuous noise in both ears. Many patients also suffer from cranial ringing. Ask the other party to speak louder, and some people can clearly feel that the sound they hear is not loud enough. When watching TV or listening to the radio, they are often asked to increase the volume, which makes the family feel deafening. His voice increased unconsciously. They often have trouble listening to conversations between others, even if they are close at hand.

Symptoms of mixed deafness also include. The hearing changes of mixed deafness are characterized by both air conduction damage and bone conduction damage. The curve is slowly decreasing, and there are air bones in the low frequency area. The conductor spacing is small and the high frequency area is not obvious. The hearing changes in mixed deafness are characterized by bothThere is air conduction damage and bone conduction damage. The curve shows a slow-down type. There is an air-bone conduction gap in the low-frequency area but not obvious in the high-frequency area. The cause of damage to both parts can be the same or different.
Generally, for those with mixed deafness, such as conductive deafness caused by suppurative otitis media, combined with labyrinthitis or bacterial toxins, ototoxic drugs, etc. penetrating into the inner ear through the cochlear window membrane, the physical and chemical properties of the labyrinth fluid will be affected. Sensory deafness occurs secondary to structural changes in stria vascularis and spiral organ. Mixed deafness caused by different causes of damage in the two parts is common, such as otitis media with presbycusis, noise deafness or deafness caused by systemic diseases.
Mixed deafness will cause hearing loss. If the eardrum is inverted, there may be symptoms of ear tightness and tinnitus. Mixed deafness can wear Hearing Aids. Taking medicine should not be effective, otherwise it will affect normal life.
