    Histological examination of 43 Plastipore ossicular prostheses, including total ossicular replacement prostheses (TORPs) and partial ossicular replacement prostheses (PORPs), revealed key findings after revision tympanoplasty surgery.

    Area of Science:

    • Otolaryngology
    • Biomaterials Science
    • Surgical Pathology

    Background:

    • Ossicular prostheses are used in tympanoplasty to restore hearing.
    • Revision tympanoplasty may be necessary due to prosthesis complications.
    • Plastipore prostheses are commonly used but their long-term histological changes are of interest.

    Purpose of the Study:

    • To describe and discuss the histological findings of Plastipore ossicular prostheses removed during revision tympanoplasty.
    • To evaluate the tissue response and degradation of Plastipore materials in vivo.

    Main Methods:

    • Histological analysis of 43 explanted Plastipore prostheses (26 TORPs, 17 PORPs).
    • Specimens were obtained during revision tympanoplasty procedures.
    • Microscopic examination focused on material integrity and surrounding tissue interface.

    Main Results:

    • Detailed histological descriptions of tissue ingrowth and foreign body reactions.
    • Assessment of material degradation, wear, and potential inflammatory responses.
    • Correlation of histological findings with clinical outcomes in revision tympanoplasty cases.

    Conclusions:

    • Histological evaluation provides insights into the long-term behavior of Plastipore prostheses.
    • Understanding tissue integration and material changes is crucial for improving prosthesis design and surgical techniques.
    • Findings inform clinical decision-making for revision tympanoplasty involving Plastipore implants.
