A middle ear implant is a hearing device that is surgically implanted into the middle ear. They help people with conductive, sensorineural or mixed hearing loss to hear. [1] Middle ear implants work by improving the conduction of sound vibrations from the middle ear to the inner ear. There are two types of middle ear devices: active and passive.
The key to minimizing side effects from hearing aids is to ensure that they are properly fit for your hearing loss. Hearing aids take time to adjust to, so be patient as your start wearing them.
Ototoxicity is the property of being toxic to the ear (oto-), specifically the cochlea or auditory nerve and sometimes the vestibular system, for example, as a side effect of a drug. The effects of ototoxicity can be reversible and temporary, or irreversible and permanent. It has been recognized since the 19th century. [1]
A sound processor behind the ear. Bone-anchored hearing aids use a surgically implanted abutment to transmit sound by direct conduction through bone to the inner ear, bypassing the external auditory canal and middle ear. A titanium prosthesis is surgically embedded into the skull with a small abutment exposed outside the skin.
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.
Conductive hearing loss (CHL) in otosclerosis is caused by two main sites of involvement of the sclerotic (or scar-like) lesions. The best understood mechanism is fixation of the stapes footplate to the oval window of the cochlea. This greatly impairs movement of the stapes and therefore transmission of sound into the inner ear ("ossicular ...
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments.
Firstly, non-auditory side-effects, such as vertigo, limit the overall number of electrodes that can deliver useful frequency information. Electrodes found to cause one of these side-effects are deactivated, resulting in fewer signals reaching the brain. In addition, the brainstem is unable to offer the same tonotopic range as the cochlea.
