Talking about the problem of senile ear damage
As people’s quality of life improves, and with the development of technology, older people with reduced hearing are gradually accepting and wearing hearing aids. However, there are many elderly patients who wear hearing aids and can hear the sound, but still can’t understand. What is the reason?
Hearing hearing aid fitting center explained: senile ear loss is a common type of sensorineural ear damage. Hearing loss due to increased age, senile ear damage is usually divided into four types: sensory, central, metabolic, and mechanical.
Sensorineural ear damage: caused by hair cell disease. The pure tone audiogram is a steep drop type high frequency hearing loss.
Central ear loss: caused by spiral ganglion cell lesions. Patients have language degeneration, and audiological performance is significantly worse than pure tone hearing, which is common in patients with hardening of the arteries.
Metabolic ear damage: usually due to defects in the chemical composition of the lymphatic fluid caused by lesions of the vascular plexus, the pure tone audiogram is a slow progressive flat hearing loss, common in patients with diabetes and kidney disease.
Mechanical ear damage: due to hardening of the basement membrane or fixation of the tibial floor. Pure tone audiograms are progressive hearing loss, common in patients with otosclerosis.
It can be seen from the above classification that patients with mechanical ear loss have better effects with hearing aids, sensorineural ear damage, metabolic ear loss, and central ear loss. Especially for central ear damage, due to the impairment of the auditory center and auditory nerve, the speech recognition ability is poor, so the wearing effect is poor.
The main problem for most elderly patients with ear damage is “audible, inaudible.” There is no significant difference in verbal comprehension between normal and normal people in a quiet environment. In the environment of noise and competitive speech, the language resolving ability is very poor. In response to this situation, we generally have the following measures:
Do a detailed explanation, because wearing a hearing aid is like wearing a denture, the patient is very uncomfortable to wear, and the output sound of the hearing aid is like the sound of the sound, they will feel very uncomfortable or even unwilling to wear it. Therefore, it is necessary to explain clearly to the patient when wearing the hearing aid. There is an adaptation process for the hearing aid and the patient is allowed to follow the steps in the rehabilitation manual.
Adhere to wearing hearing aids for a long time. The reason for the decline in hearing loss in the elderly is the deterioration of the auditory organs that these patients can hear but cannot hear. Based on the principle of exhaustion and retreat, we advocate long-term wearing of hearing aids to make the degraded auditory function slowly and maximally improved.
