Deafness can be divided into acoustic deafness and sensorineural deafness. Due to diseases of the outer ear or middle ear, the sound energy reaching the inner ear is weakened, causing hearing loss, which is called acoustic deafness, also known as conductive deafness. Hearing impairment caused by lesions in the cochlear spiral organ of the inner ear is called sensorineural deafness (clinically, conductive deafness in the inner ear caused by lesions of the endolymph and basilar membrane is also summarized in sensorineural deafness), and nerve conduction pathways occur. Deafness caused by lesions is called neurological deafness.


Are deaf people really unable to hear? Some are completely deaf, and some still have residual hearing. If there is residual hearing and Hearing Aids are effective, you can consider hearing aid fitting.


Normally, people can hear breathing sounds of only 10 decibels, just because in noisy environments, the ears automatically ignore weaker sounds, but whispering . Speak with breath, which is about 25 decibels. Logically speaking, it should be easily heard within a distance of one meter. If you can't hear it, or you can hear it, but you can't judge the meaning, you should be careful. There's something wrong with my ears.

Because the auditory nerve is damaged and you cannot hear, there is no way to restore your hearing. If the ear disease lasts for a long time, it may also cause damage to the auditory nerve. Therefore, once you start to feel hearing loss, it is best to Go to an otolaryngologist to describe your symptoms and do a comprehensive hearing test to confirm if there is a problem.

What to do if you are deaf

If the patient is deaf, he must go to the otolaryngology department of the hospital for a detailed examination. It is recommended that patients complete pure tone audiometry and acoustic immittance. Determine the specific degree and type of the patient’s deafness. At the same time, middle ear CT can also be improved to rule out abnormalities in anatomical structures. If you have neurological deafness, you can use drugs that improve circulation and nourish nerves. Commonly used clinically are batroxobin injection, Xueshuantong injection or vinpocetine injection. Patients with neurotrophic drugs can choose intramuscular injection of adenosylcobalamin or oral dispersible tablets of methylcobalamin. ifIt is conductive deafness, often caused by inflammation in the patient's middle ear cavity. It is recommended that patients take active anti-inflammatory measures, take cephalosporin antibiotics orally, and at the same time use levofloxacin ear drops for anti-inflammation. They can also take eucalyptus, lemon and pinole enteric-coated soft capsules to promote the discharge of fluid in the middle ear cavity. After active treatment, the patient's deafness should improve to some extent.
