    Area of Science:

    • Otolaryngology
    • Biomaterials Science
    • Surgical Innovation

    Background:

    • Chronic middle ear disease presents complex reconstructive challenges.
    • Existing methods may have limitations in addressing extensive defects.
    • Hydroxyapatite offers biocompatibility and structural integrity for ossicular reconstruction.

    Purpose of the Study:

    • To describe a novel surgical approach for chronic middle ear disease using hydroxyapatite prostheses.
    • To evaluate the feasibility of reconstruction independent of pathogen eradication.
    • To present techniques for reconstructing the posterior canal wall and middle ear chain defects.

    Main Methods:

    • Open surgical exploration of the middle ear.
    • Reconstruction of the posterior canal wall using porous hydroxyapatite prostheses.

  • Reconstruction of middle ear chain defects with dense hydroxyapatite prostheses.
  • Utilizing total alloplastic middle ear prostheses for mobile bare footplate cases.

    • Main Results:

    • Successful reconstruction of the posterior canal wall was achieved with hydroxyapatite.
    • Middle ear chain defects were effectively reconstructed using hydroxyapatite prostheses.
    • A viable method for total alloplastic reconstruction was demonstrated for specific footplate conditions.

    Conclusions:

    • Hydroxyapatite prostheses provide a versatile solution for chronic middle ear disease reconstruction.
    • Open surgery with hydroxyapatite allows for simultaneous eradication and reconstruction.
    • This approach offers a promising alternative for complex middle ear reconstructions.
