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.
This procedure is required if there is a damage to the bone chain of the middle ear. Commonly affected bone is the long process of incus, where it gets necrosed. The bone chain can be repaired using autograft of incus or cartilage. Prosthetic implants made of hydroxyapatite or teflon are also used.
Stapedectomy is a surgical procedure in which the stapes bone is removed from the middle ear and replaced with a prosthesis. If the stapes footplate is fixed in position, rather than being normally mobile, the result is a conductive hearing loss. There are two major causes of stapes fixation.
Many FM systems are very small in size, allowing them to be used in mobile situations. The audio induction loop permits the listener with hearing loss to be free of wearing a receiver provided that the listener has a hearing aid or cochlear implant processor with an accessory called a "telecoil". Listeners without a telecoil must carry a ...
They dispense, manage, and rehabilitate hearing aids and assess candidacy for and map hearing implants, such as cochlear implants, middle ear implants and bone conduction implants. They counsel families through a new diagnosis of hearing loss in infants, and help teach coping and compensation skills to late-deafened adults.
Endoscopic ear surgery (EES) is a minimally invasive alternative to traditional ear surgery and is defined as the use of the rigid endoscope, as opposed to a surgical microscope, to visualize the middle and inner ear during otologic surgery. [1]
In 2003, the company acquired the Vibrant Soundbridge, a new type of active middle ear implant pioneered by American inventor Geoffrey Ball. [8] It was MED-EL’s first non-cochlear implant product. Further non-cochlear implant products followed with the Bonebridge active bone conduction implant in 2012 and the Adhear non-surgical bone ...
A direct acoustic cochlear implant - also DACI - is an acoustic implant which converts sound in mechanical vibrations that stimulate directly the perilymph inside the cochlea. The hearing function of the external and middle ear is being taken over by a little motor of a cochlear implant, directly stimulating the cochlea. With a DACI, people ...
