Deafness is a progressive sensorineural deafness that occurs with age. The pathology is characterized by atrophy and degeneration of the nerve tissue in the inner ear, such as degeneration of the hair cells of the cochlear spiral apparatus, and degeneration of the auditory nerve and auditory center. Generally speaking, most elderly people who suffer from deafness have a hearing impairment before middle age. Some of the diseases that cause hearing impairment have stopped developing and the hearing remains at its original level and does not continue to decline, but a large proportion of the diseases, such as chronic suppurative otitis media, continue to develop and deteriorate with age without being controlled, and not only does the hearing loss continue to worsen, but even serious complications arise. In older adults, deafness can also be caused by ear diseases, other systemic diseases, damage from certain ototoxic drugs, noise and aging. Deafness is not difficult to prevent and treat if I have some knowledge of the condition and pay attention to it.
