The remainder underwent Type III tympanoplasty with the tympanic membrane placed directly over the stapes suprastructure. |
|
That bone turned out to be the stapes, which transmitted vibrations to the animal's inner ear. |
|
This reduces the importance of the stapes in supporting the braincase ventrally. |
|
One of the main problems causing failure in revision stapes surgery is the inability to adequately assess the oval window neomembrane. |
|
Although stapes surgery is the dominant application of lasers in otology, lasers have been used in multiple other otological cases. |
|
This bone deposition leads to fixation of the stapes at the oval window, preventing normal vibration. |
|
A reduced hyomandibula associated with the quadrate in a fish's visceral skull evolved to form the ear ossicle called the stapes, or columella. |
|
The stapes terminates at a well-defined fenestra ovalis, suggesting that the stapes was specialized for hearing. |
|
Even with these changes, we still have concerns that the position and extent of the stapes is inconsistent between the two views of Ichthyostega. |
|
Urbantschitsch has provided detailed measurements of the malleus, incus and the stapes. |
|
Mammals have three, the stapes, the malleus, and incus, the last two being the old reptilian jaw joint still conserved deep within our ear. |
|
A perilymph fistula will frequently accompany injuries to the stapes such as subluxation or fracture. |
|
Remnants of the pectoral girdle are present, perhaps due to the presence of an operculum-opercularis-like connection to the stapes. |
|
Mr Bell removed the stapes, and attached to the end of the incus a style of hay about an inch in length. |
|
The joint between the incus and stapes is likewise a cartilagenous joint, with a tendency to ossify in older humans. |
|
It remains unclear, however, how the stapes related to the quadrate, and possibly to the posterior extension of its mandibular condyle, in Haasiophis. |
|
It has commonly been inferred that the stapes, a bone in the cheek region of early tetrapods, was important for transmitting airborne vibrations to the inner ear. |
|
Sound is conducted through the middle ear via the stapes or columella. |
|
The whole system, from the auricle to the stapes, is the conducting apparatus of the ear. |
|
In the oval window, which occupies the entire lateral surface of the otic capsule, is a stapes. |
|
|
In reptiles that can hear, the tympanum vibrates in response to sound waves and transmits the vibrations to the stapes. |
|
The air pressure on either side of the eardrum is normally kept equal for proper functioning of the middle ear structures, namely the malleus, incus and stapes bones. |
|
At moderate sound pressures, the vibrations are passed on to the stapes, and the whole ossicular chain moves as a single mass. |
|
The footplate of the stapes, together with the other ossicles, transmits sounds from the eardrum to the inner ear. |
|
An X ray of the ear using computed tomography may be made to demonstrate that the footplate of the stapes has been invaded by otosclerosis. |
|
Today this operation, known as stapedectomy, is the one most often used to correct fixation of the stapes by otosclerosis. |
|
Any abnormality in the system, from wax in the ear canal to fixation of the stapes by otosclerosis, can cause a conductive hearing loss. |
|
These are the malleus, or hammer, the incus, or anvil, and the stapes, or stirrup. |
|
Vibrations in the eardrum are transmitted to the hearing ossicles: the hammer, the anvil, and the stirrup, or malleus, incus and stapes. |
|
Mammals hear sounds after they are transmitted from the outside world to their inner ears by a chain of three bones, the malleus, incus, and stapes. |
|
The left stapes is preserved, although not in life position. |
|
Reptiles have a single ear ossicle, the stapes or stirrup bone. |
|
Material and methods: retrospective study for 82 operated patients for cholesteatoma with lysis of the cruras of the stapes. |
|
Used after an operator that removes the head of the stapes, the machine can straighten the duck and remove much of the wax. |
|
The access to certain of our service is conditioned with a password which make easier, individualization, and confidentiality for your stapes. |
|
The mechanism seems to be that noise energy is transmitted from the stapes footplate into the vestibular part of the labyrinth, especially to the sacculus and the utriculus. |
|
They suggested that vibrations pass from the substrate to the jaw, which are juxtaposed, and then pass via the jaw articulation to the incus and stapes. |
|
This chain is linked on one side to the tympanic membrane by one of the extremities of the malleus and on the other side to the inner ear by the stapes. |
|
However, there may be considerable freedom of motion and some loss of energy at the joint between the incus and the stapes because of their relatively loose coupling. |
|
A conductive hearing loss can be theresult of a blockage in the external ear canal or can be caused by any disorderthat unfavorably effects the middle ear's ability to transmit the mechanical energyto the stapes footplate. |
|
|
The stapes does not move in and out but rocks back and forth about the lower pole of its footplate, which impinges on the membrane covering the oval window in the bony plate of the inner ear. |
|
In 1956 it was found that the fixed stapes could be removed and replaced by a plastic or wire substitute in cases in which it could not be mobilized. |
|
Summary: Objective: The prostheses known as biocompatible are usually proposed for columellar repair in absence of stapes but at which cost and which long-term tolerance? |
|
The incus is the ossicle most susceptible to disruption as it has less ligamentous support than the malleus and stapes. |
|
The long process of the incus is bent near the lower end and carries a small knoblike bone that is jointed loosely to the head of the stapes the third and smallest of the ossicles. |
|
The stapes does closely resemble a stirrup. |
|
Detection of osteoprotegerin and TNF-alpha mRNA in ankylotic stapes footplates in connection with measles virus positivity. |
|
In such cases, you have already performed a stapes mobilization by inadvertently mobilizing the stapes via the incus. |
|
The mechanical vibrations of the stapes footplate at the oval window creates pressure waves in the perilymph of the scala vestibuli of the cochlea. |
|
The study analyzed the tiny ear bones, the malleus, incus and stapes, from two species of early human ancestor in South Africa. |
|
The stapes is homologous with the entire stapedial structure of reptiles, which in turn was derived from the hyomandibular arch of primitive vertebrates. |
|
In otosclerosis, a gradual buildup of new spongy bony tissue around the stapes welds it against the wall of the surrounding bone and immobilizes it, preventing the vibrations that permit soundwaves to travel through the ear. |
|
Otosclerosis is a primary disorder of the labyrinthine capsule characterized by new bone formation and often involving the footplate of the stapes. |
|
In the human body, in which organ are the malleus, incus and stapes bones located? |
|
The footplate of the stapes develops and ossifies in conjunction with the otic capsule and thus takes its origin from the otic placode in the embryo. |
