    Ceramic prostheses served as effective columella grafts in chronic middle ear disease surgery. These implants showed no adverse tissue reactions, offering an acceptable alternative to bone for hearing reconstruction.

    Area of Science:

    • Otolaryngology
    • Biomaterials Science
    • Surgical Innovation

    Background:

    • Chronic middle ear disease often necessitates surgical reconstruction of the middle ear ossicular chain.
    • The columella, connecting the stapes footplate to the tympanic membrane or graft, is crucial for sound transmission.
    • Absence or damage to the stapes superstructure requires prosthetic solutions.

    Purpose of the Study:

    • To evaluate the efficacy and biocompatibility of ceramic prostheses as columella grafts.
    • To assess hearing outcomes in patients undergoing middle ear reconstruction with ceramic implants.
    • To compare ceramic grafts with traditional bone grafts in specific surgical contexts.

    Main Methods:

    • Utilized ceramic stems with ossicle caps or cap-shaped head prostheses as columellae in 41 ear surgeries (1982-1985).

  • Procedures included primary cholesteatoma operations (12 ears) and revision surgeries (23 ears).
  • Follow-up assessed hearing improvement and tissue response to the ceramic material.

    • Main Results:

    • Significant hearing improvement was observed in ears with good aeration and no severe tympanic mucosa disease.
    • Ears with extensive tympanic disease showed limited hearing gains post-surgery.
    • No adverse tissue reactions or extrusion of the ceramic prostheses were noted.

    Conclusions:

    • Ceramic prostheses are a safe and viable alternative to bone for columella reconstruction in chronic middle ear disease.
    • Successful outcomes depend on the aeration status and extent of disease in the middle ear.
    • Ceramic implants demonstrate excellent biocompatibility, making them suitable for long-term use.
