What is senile deafness?

Senile deafness

Definition of senile convulsions

Senile sputum refers to deafness caused by aging of the auditory system with age, and is the most common hearing disorder in the elderly.


The occurrence of senile hearing loss is not only related to the aging of the auditory system, but also affected by other aspects.

1) disease effects

Hypertension, coronary heart disease, hyperlipidemia, diabetes, otitis media, etc. can affect the outer hair cells and blood vessel lines, causing hearing loss.

2) diet and lipid metabolism

Excessive dietary fat content can cause lipid deposition, degeneration of tiny blood vessels, microcirculation disturbances, and senile convulsions.

3) medication situation

Some drugs that damage the vestibular nerve or the cochlear auditory nerve can also accelerate senile convulsions, which can lead to permanent paralysis. Common ototoxic drugs, such as: neomycin, caramycin, gentamicin, streptomycin.

4) bad habits

Smoking, incorrect earing, long-term exposure to noise, etc., will have varying degrees of impact on the disease.


According to the pathogenesis, the pathological changes of senile sputum can be divided into 4 types: sensorinenal senile sputum, neurological senile sputum, vascular senile sputum and cochlear senile senile sputum.

Audiological performance

1) hearing situation

The decline in high-frequency hearing is particularly evident, and the ability to understand speech declines, especially in noisy environments. There is often a phenomenon of auditory rejuvenation, that is, “small inaudible, loud and noisy”, often accompanied by high-pitched tinnitus, tinnitus symptoms usually appear before deafness.

2) Audiological examination

Otoscope: There is no characteristic change of the tympanic membrane. Generally, the tympanic membrane of the elderly is turbid, and calcium spots, atrophy and invagination are also seen.

Pure tone audiometry: for sensorineural hearing loss, common hearing curves have steep drop, slow down, flat and so on. It can also be combined with conductive hearing loss to present mixed sputum, but still dominated by sensorineural hearing loss.

Otoacoustic emission: Early cochlear damage can be found to help identify sinus and posterior sinus lesions.

Speech audiometry: The speech recognition rate is reduced, and in most cases, the hearing loss is more serious than pure speech.


60 older adults have progressive neurite neuritis, excluding other causes, such as drug toxicity, noise, acoustic damage, Meniere’s disease, ear sclerosis, tympanosclerosis, middle ear adhesions, acoustic neuroma Diagnosis can be made with hyperlipidemia, diabetes, and autoimmune inner ear disease.


Pay attention to diet, reduce the intake of fatty foods, quit smoking, lower blood fat, and actively prevent cardiovascular diseases;

Avoid contact with noise and avoid the application of ototoxic drugs;

Pay attention to work and rest, keep your mood comfortable;

Conduct appropriate sports activities;

Improve blood circulation in the brain and inner ear.


Senile sputum is an irreversible degenerative disease of the auditory system, and there is currently no effective therapy. Vitamins, trace elements and vasodilators have no definitive effect on this disease.

It is recommended to wear suitable hearing aids as early as possible to help the elderly improve their communication skills and improve their quality of life. Pay attention to avoid loud shouting when talking with patients. Speech should be as slow and clear as possible.
