In cases of profound or total deafness, a cochlear implant is a specialised device that may restore a functional level of hearing. SNHL is at least partially preventable by avoiding environmental noise, ototoxic chemicals and drugs, and head trauma, and treating or inoculating against certain triggering diseases and conditions like meningitis .
Autoimmune inner ear disease (AIED) was first defined by Dr. Brian McCabe in a landmark paper describing an autoimmune loss of hearing. [2] The disease results in progressive sensorineural hearing loss (SNHL) that acts bilaterally and asymmetrically, and sometimes affects an individual's vestibular system.
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.
Some management options include hearing aids, cochlear implants, middle ear implants, assistive technology, and closed captioning; [9] in movie theaters, a Hearing Impaired (HI) audio track may be available via headphones to better hear dialog. [118] This choice depends on the level of hearing loss, type of hearing loss, and personal preference.
The symptoms of cochlear hydrops fluctuate, and the condition may stabilize or go away on its own after several years. However, because the organ of Corti undergoes stress during the hydrops episodes, long-term hearing loss, tinnitus, or hyperacusis is possible. It is considered by some that cochlear hydrops is an early form of Meniere's disease.
The internal implant sends the signals to the electrode array. The design of the electrode array is the key difference between a cochlear implant and an ABI. Whereas the electrode array for a CI is wire-shaped and is inserted into the cochlea, the electrode array of an ABI is paddle-shaped and is placed on the cochlear nucleus of the brainstem. [3]
Aug. 18—Q: I need information on humane rattlesnake-proofing techniques for dogs. It seems to me that keeping your dog on leash would be a better solution, so I don't need it for myself.
There is no treatment to correct an enlarged vestibular aqueduct. Any hearing loss will need management with amplification and support in education and at work. If the hearing loss becomes severe to profound, cochlear implants can be of significant value. Vestibular disturbance is usually short-lived and associated with head trauma, but ...
