The footplate vibrates when the pressure is transmitted via the ossicular chain.
Indications for use of an ossicular replacement prosthesis include:
The Kartush Hydroxyappetite Ossicular Struts were designed in 1987 to replace the incus and stapes bones.
The stapedotomy method is not applicable in those relatively rare cases that involve scleroris of the entire ossicular chain.
Ossicular chain reconstruction is often performed in conjunction with repair of ear drum perforations, referred to as tympanoplasty.
As the stapes is ankylosed in otosclerosis, the lateral end of the ossicular chain may still be quite mobile.
A TORP replaces the entire ossicular chain while a PORP replaces only the incus and malleus but not the stapes.
This greatly impairs movement of the stapes and therefore transmission of sound into the inner ear ( ossicular coupling ).
When a cholesteatoma or granulation tissue is present in the middle ear, the degree of hearing loss and ossicular destruction is even greater.
Thus, a high resonant-frequency pathology such as otosclerosis can be differentiated from low resonant-frequency pathologies such as ossicular discontinuity.
