2. Inner ear regeneration - Wikipedia

   en.wikipedia.org/wiki/Inner_Ear_Regeneration

   Because mammals have very limited hair cell regenerative capacity, humans have developed alternative methods of dealing with hearing loss. Hearing aids are devices that sit in the ear and amplify sound, which helps with age-induced partial hair cell loss. [10] Cochlear implants are a more invasive treatment that bypass the hair cells completely ...

3. Ototoxic medication - Wikipedia

   en.wikipedia.org/wiki/Ototoxic_medication

   Various ototoxic effects are manifested by using antimalarial drugs, with dizziness being one of the most common one. Other effects include vestibular symptoms, hearing loss and tinnitus, which can appear to be both temporary or permanent. [25] Nonetheless, the underlying mechanisms of antimalarial-induced ototoxicity are still poorly understood.

4. Regenerative medicine - Wikipedia

   en.wikipedia.org/wiki/Regenerative_medicine

   Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". [1] This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair mechanisms to functionally heal previously irreparable tissues ...

5. Sensorineural hearing loss - Wikipedia

   en.wikipedia.org/wiki/Sensorineural_hearing_loss

   Hearing loss that worsens with age but is caused by factors other than normal aging, such as noise-induced hearing loss, is not presbycusis, although differentiating the individual effects of multiple causes of hearing loss can be difficult. One in three persons have significant hearing loss by age 65; by age 75, one in two.

6. Merkel cell - Wikipedia

   en.wikipedia.org/wiki/Merkel_cell

   Merkel cell. Merkel cells are found in the skin and some parts of the mucosa of all vertebrates. In mammalian skin, they are clear cells found in the stratum basale [2] [3] (at the bottom of sweat duct ridges) of the epidermis approximately 10 μm in diameter.

7. Presbycusis - Wikipedia

   en.wikipedia.org/wiki/Presbycusis

   Presbycusis (also spelled presbyacusis, from Greek πρέσβυς presbys "old" + ἄκουσις akousis "hearing" [1]), or age-related hearing loss, is the cumulative effect of aging on hearing. It is a progressive and irreversible bilateral symmetrical age-related sensorineural hearing loss resulting from degeneration of the cochlea or ...
