First, it contains a mechanism of three bones, called the auditory ossicles, connecting the eardrum and the inner ear.
The auditory ossicles in the middle ear pick up these oscillations and transfer them to the fluid through the oval window, one of two flexible surfaces between the cochlea and middle ear.
Ossiculoplasty - Procedure where the ossicular chain is repaired in order to try and improve hearing.
Otherwise, surgery can be performed by an ENT specialist to reconstruct the Ossicular chain.
The invention is directed to a fixation apparatus (100) and method for interfacing an implantable hearing aid actuator (10) with the ossicular chain of a patient.
The ossicular chain ensures the transmission of acoustic pressure from the air to the cochlear fluids (see animation).
Exploration of the middle ear surgically with correction of the ossicular chain or insertion of a prosthesis is called an ossiculoplasty.
In case of destruction of an element of the chain of ossicles, the replacement is provided by one of the usable ossicles after it has been reshaped or by a prosthesis made of biocompatible materials.
The chain of ossicles transmits and amplifies these vibrations (mechanical conduction) and is transmitted to the inner ear.
The chain of ossicles transmits and amplifies these vibrations (mechanical conduction) and is transmitted to the inner ear.
Cochlear receptors and audition: the chain of ossicles transmits the vibrations of the eardrum to the oval window whilst amplifying them.
In case of destruction of an element of the chain of ossicles, the replacement is provided by one of the usable ossicles after it has been reshaped or by a prosthesis made of biocompatible materials.
This complex, called ossicles or ossicular chain [ 84 ], will play the role of mediator between the sound arérique environment outside of the eardrum and the fluid environment of the inner ear beyond the oval window.
An inconspicuous hearing system is described that uses a coil (20) to electromagnetically couple with, and therefore drive, a permanent magnet (10) attached to the tympanic membrane (12) or ossicular chain.
Note: Schematic view of the middle ear cavity showing how the activity of the ossicular chain can be modulated by the tensor tympani (9) and stapedial (5) muscles
Frequently, the rigidity of the ossicles provides this hearing loss transmission.
The back wall has a recess (e.g., blind hole) configured to be coupled to an auditory ossicle.
Middle ear, where are located the eardrum and ossicles allows transmission
Output mechanical coupling is directly to the inner ear, or through an ossicular element such as the malleus, stapes, or incus.
Output mechanical coupling is directly to the inner ear (60, 61, 62), or through an ossicular element such as the malleus (40), stapes (50), or incus (45).
Type 2 involves repair of the tympanic membrane and middle ear in spite of slight defects in the middle ear ossicles.
A transducer electrically coupled to the detectors is configured to vibrate at least one of an eardrum or ossicle in response to the first wavelength of light and the second wavelength of light.
With respect to the measurement of stapedius reflexes (a reaction of the auditory system that stiffens the ossicles to protect itself from excessively loud noise), it reflects the contribution of the brainstem.
The membrane is configured to move in response to movement from the auditory ossicle, and the vibration sensor is configured to measure the movement of the membrane and to convert the measurement into an electrical signal.
Permanent hearing loss from fluid is rare, but it can occur in children whose fluid remains untreated, resulting in structural changes in the eardrum or hearing bones.
