A novel "tumulus" surgical technique using autologous cartilage effectively stabilizes total ossicular replacement prostheses (TORP), preventing displacement and extrusion in hearing reconstruction surgery.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Biomaterials in Otology

Background:

  • Total ossicular replacement prostheses (TORP) can fail due to displacement or extrusion, often linked to tympanic membrane retraction.
  • Current stabilization methods involve foreign or resorbable materials, posing potential risks.
  • A need exists for a simple, cost-effective, and biocompatible method to enhance TORP stability.

Purpose of the Study:

  • To introduce and evaluate a novel "tumulus" surgical technique for stabilizing TORPs.
  • To assess the efficacy of using autologous cartilage fragments for TORP fixation.
  • To compare the outcomes of this technique with existing methods for preventing prosthesis displacement and extrusion.

Main Methods:

  • A "tumulus" technique was developed using small fragments of autologous cartilage to secure the TORP.

  • The technique was applied to 31 patients undergoing TORP reconstruction.
  • Patient outcomes, including prosthesis stability and audiometric results, were reviewed.

    • Main Results:

    • No instances of prosthesis displacement were observed in the 31 treated cases.
    • Only one case (3.2%) of prosthesis extrusion occurred.
    • Audiometric results were comparable to the best outcomes reported in existing literature.

    Conclusions:

    • The "tumulus" technique offers a simple and effective method for stabilizing TORPs using readily available autologous cartilage.
    • This approach significantly reduces the risk of prosthesis displacement and extrusion.
    • Autologous cartilage stabilization presents a safe, cost-effective alternative for improving TORP outcomes in otologic surgery.
