(+info)Ossicular replacement is a surgical procedure in which the damaged or diseased ossicles (the three smallest bones in the middle ear, namely the malleus, incus, and stapes) are replaced with artificial prostheses. This procedure is often performed to correct hearing loss caused by various conditions such as chronic otitis media, cholesteatoma, or ossicular chain discontinuity.
The artificial prostheses used in ossicular replacement can be made of various materials, including ceramic, plastic, or metal. The choice of material depends on several factors, including the patient's individual needs and preferences, the size and shape of the remaining ossicles, and the surgeon's experience and preference.
The goal of ossicular replacement is to improve hearing by restoring the normal function of the ossicular chain, which is responsible for transmitting sound vibrations from the eardrum to the inner ear. By replacing the damaged or missing ossicles with artificial prostheses, the surgeon can help to restore the patient's ability to hear and communicate effectively.
An ossicular prosthesis is a medical device used to replace one or more of the small bones (ossicles) in the middle ear that are involved in hearing. These bones, known as the malleus, incus, and stapes, form a chain responsible for transmitting sound vibrations from the eardrum to the inner ear.
An ossicular prosthesis is typically made of biocompatible materials such as ceramic, plastic, or metal. The prosthesis is designed to bypass damaged or missing ossicles and reestablish the connection between the eardrum and the inner ear, thereby improving hearing function. Ossicular prostheses are often used in surgeries aimed at reconstructing the middle ear, such as tympanoplasty or stapedectomy, to treat various types of conductive hearing loss.

Prostheses1
- Reproducibility of 3D printing was good if the diameter of the prosthesis shaft was 0.6 mm. 3D-printed partial ossicular replacement prostheses were easy to manipulate during surgery even though they were a bit stiffer and less flexible than conventional titanium prostheses. (bvsalud.org)
Stapes8
- Indications for use of an ossicular replacement prosthesis include: Chronic middle ear disease Otosclerosis Congenital fixation of the stapes Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery Surgically correctable injury to the middle ear from trauma Food and Drug Administration. (wikipedia.org)
- The procedure, called a stapedectomy, involves removal of the stapes and replacement with an artificial prosthesis. (hearingmatters.org)
- The mobilization era began in the late 1800s when Kessel attempted stapes mobilization without ossicular chain reconstruction in cases where it was noted to be fixed. (medscape.com)
- Though ear bone replacements are not as common as their orthopedic cousins, they are options when the malleus, incus, or stapes become damaged or fixated resulting in hearing loss. (fauquierent.net)
- The most common forms of traumatic ossicular disruption are incus-stapes or malleus-incus dislocation. (ejao.org)
- Consequently, disruption between the incus and stapes or malleus and incus is more common than ossicular fractures because these portions are the most vulnerable portions of the ossicles. (ejao.org)
- Dr Chang specialises in minimally invasive Stapedectomy surgery for the removal of the stapes and its replacement with a prothesis. (myentdoc.com.au)

- Despite advances in prosthesis materials, operating microscopes and surgical techniques during the last 50 years, long-lasting hearing improvement remains a challenge in ossicular chain reconstruction. (bvsalud.org)
