Therefore, we can conclude that Myo3a mutant mice exhibited a gradual hearing loss, which is similar to the characteristics of presbyacusis

"Hearing loss that occurs with the aging process is called presbyacusis
, which begins at or around the age of 40 for most individuals.

These range from wax blocking the ear canal, causing a temporary problem, to age-related changes to the sensory cells of the cochlea (presbyacusis
), or otosclerosis - a condition in which the ossicles of the middle ear harden and become less mobile, through to head injury or brain damage.
, or age-related late-onset HL, is believed to have a multifactorial etiology, with the most important contributory factor being heredity (Ahituv & Avraham, 2000).
results not only from loss of internal ear hair cells but also from degeneration in the central auditory pathways and auditory cortex(2)(3)(4).
Arteriolar sclerosis as a cause of presbyacusis
Tinnitus is generally believed to result from a peripheral defect (cochlear or nerve lesion) caused by triggers such as noise trauma, presbyacusis
, or ototoxic medication, thereby inducing deafferentation [2, 5].
Common causes of sensorineural hearing loss include presbyacusis
, chronic suppurative otitis media, Meniere's disease, ototoxic medications and noise exposure.6 The other accompanying symptoms of these conditions usually tend to be associated with the hearing loss and are quite distressful to the patient.
