    Summary
    This summary is machine-generated.

    Hydroxyapatite prostheses were used to reconstruct the middle ear in 35 patients. This approach allowed for physiological reconstruction during radical middle ear surgery, showing promising results in bone and cavity defects.

    Area of Science:

    • Biomaterials Science
    • Otolaryngology
    • Surgical Reconstruction

    Background:

    • Middle ear reconstruction is crucial after radical surgery.
    • Traditional methods may not fully restore middle ear function.
    • Need for biocompatible materials for effective reconstruction.

    Purpose of the Study:

    • To evaluate the efficacy of hydroxyapatite prostheses for middle ear reconstruction.
    • To assess the combination of radical surgery with physiological reconstruction.
    • To investigate the use of different hydroxyapatite forms for specific defects.

    Main Methods:

    • Utilized hydroxyapatite prostheses (dense and porous) in 35 patients.
    • Interposition prostheses for missing incus.
    • Canal wall prostheses for bony defects.

  • Total alloplastic implants for complex cavities.

    • Main Results:

    • Successful reconstruction in patients with an average follow-up of 2.5 years.
    • Demonstrated feasibility of combining radical surgery with physiological reconstruction.
    • Hydroxyapatite effectively addressed incus absence, canal wall defects, and middle ear cavities.

    Conclusions:

    • Hydroxyapatite prostheses offer a viable solution for middle ear reconstruction.
    • This technique enables physiological restoration alongside radical surgical procedures.
    • The study supports the use of tailored hydroxyapatite implants for diverse middle ear defects.
