How to identify the type of deafness–What are the types of deafness?

Old people and children are high-risk people with deafness, but the incidence of morbidity among young people has gradually increased in recent years. Especially the white-collar workers who have relatively high pressure, there are many reasons for deafness in life, but they are diagnosed because of different types. The method is also different. Different types of deafness diseases have different identification measures, but the specific differences are different. We take the identification measures of three kinds of deafness diseases: conductive deafness and sensorineural deafness and mixed deafness. Explain to everyone.

Conductive sputum: It is caused by lesions in the middle ear of the outer ear, which causes obstacles in the sound conduction process and causes deafness. Common causes of convulsions are external auditory canal, Foreign body, inflammation, congenital ear canal atresia, acute and chronic suppurative otitis media, acute and chronic non-suppurative otitis media, congenital malformation, tumor, bullous tympanitis, early stage of otosclerosis.

Sensorineural hearing loss: refers to the lesions of the cochlear spiral can not turn the sound waves into nerve excitation or the nerve and its central pathways can not be excited Afferent, or cerebral cortical central lesions can not distinguish the language, collectively known as sensorineural hearing loss. Such as Meniere’s disease, ear drug poisoning, lost, noise Injury, acoustic neuroma, etc.

Hearing deafness due to hearing loss caused by lesions in the inner ear cochlear auger(Clinically, the internal and external lymph And the inner ear sound conduction 引起 caused by basement membrane lesions is also summarized in sensorineural deafness)Deafness called neuropathy caused by lesions in the nerve conduction pathway deaf. However, it is often difficult to identify the difference between the two in clinical practice, so the two are often combined into a sensory sound-neural deafness.

Therefore, clinically Acupuncture and morbidity, drug or chemical poisoning, labyrinthitis, membrane labyrinth, tibia fracture, acoustic neuroma, extracranial Deafness and senile deafness caused by injury, cerebrovascular accident, cerebral arteriosclerosis or spasm can be summarized in sensorineural deafness.

Mixed 聋: There are lesions in both the sound and the sensory mechanism. Such as long-term chronic suppurative otitis media, advanced ear sclerosis, blasting sputum and so on.

Now everyone should know that there are differences in the identification of different types of deafness diseases. In other words, it is a matter of different treatments. It is impossible to treat them equally. Everyone must really understand the true meaning of this sentence.
