Ossicular prosthesis, total

Ossicular prostheses for total reconstruction replace the entire ossicular chain (malleus, incus, and stapes) when damaged or absent, restoring sound transmission from the eardrum to the inner ear. Clinically, they address severe conductive hearing loss due to trauma, otosclerosis, congenital malformations, or chronic middle ear conditions where partial or partial ossicular replacement is insufficient.

These devices are sterile, implantable implants usually made from biocompatible polymers or metals like titanium. Regulation varies by jurisdiction, with classification depending on risk factors like implantation depth and material properties; they are typically supplied as single-use or reusable surgical implants, requiring surgical placement by otolaryngologists.
