Neural deafness

Introduction Neurological deafness refers to a syndrome in which the auditory nerve of the inner ear and the auditory center of the brain occur, and causes hearing loss and even hearing loss, often accompanied by deafness. In the case of neurological deafness, it actually refers to "sensory neuropathic paralysis", including lesions of the cochlea, as well as lesions of the auditory nerve, and even some of the lesions of the central nervous system, and not simply the problem of the auditory nerve. Different types of neurological deafness showed slight differences. The main manifestations were gradual hearing loss to unilateral or bilateral ear to varying degrees of deafness, accompanied by tinnitus and nausea in the ear. About half of the patients were accompanied by dizziness and nausea. And vomiting symptoms.

Cause

Modern medicine believes that the causes of neurological deafness can be as follows:

1 pediatric continuous use of antibiotics such as streptomycin, kanamycin, gentamicin and other toxic deafness after illness.

2 Sudden deafness caused by viral infection or embolization of the inner ear.

3 Infectious deafness caused by infectious diseases such as meningitis, measles and typhoid fever.

4 Detonation deafness caused by trauma or knocking or noise.

an examination

Hearing test, Otolaryngology, CT examination, Audiogram, Cochlear electrogram, Language examination

The clinical manifestations are mainly due to hearing impairment, loss or even disappearance. Children often have snoring or other various sounds in their ears, and the children feel more obvious in a quiet environment. May be associated with fever, headache, irritability, bloating, backache and other systemic symptoms.

Other auxiliary inspections:

1. ENT examination and auditory examination.

2. Bottom of the skull, CT and MRI.

3. Other necessary optional auxiliary examination items include chest X-ray and ECG.

Differential diagnosis

Differential diagnosis of neurological deafness:

1. Conductive deafness: Hearing impairment caused by external or middle ear lesions is called conductive deafness.

2, cochlear deafness: cochlear deafness can cause hearing impairment. Because the blood supply to the cochlea is relatively fragile, it is easily damaged. All lesions in the cochlea can cause cochlear deafness.

3, central deafness: central deafness is one of the manifestations of hearing impairment, including brain stem central deafness and cortical deafness.

The clinical manifestations are mainly due to hearing impairment, loss or even disappearance. Children often have snoring or other various sounds in their ears, and the children feel more obvious in a quiet environment. May be associated with fever, headache, irritability, bloating, backache and other systemic symptoms.
