Use of Allogeneic Rib Cartilage for Microtia Repair: Preliminary Data on a Single Institutional Experience.

The Journal of craniofacial surgery·2025

This study introduces a novel technique for microtia reconstruction using 3D interlocking templates and allogeneic cartilage. This method improves efficiency and reduces donor-site morbidity compared to traditional approaches.

Area of Science:

  • Pediatric Plastic Surgery
  • Craniofacial Reconstruction
  • Biomaterials in Surgery

Background:

  • Microtia reconstruction is a complex pediatric plastic surgery procedure.
  • Traditional autologous rib cartilage reconstruction has limitations including operator dependency and donor-site morbidity.
  • Allogeneic cartilage offers an alternative, but framework fabrication is challenging.

Purpose of the Study:

  • To describe a novel technique for auricular framework construction using 3D interlocking templates and allogeneic cartilage.
  • To present allogeneic auricular reconstruction as a potential first step in a reconstructive ladder.
  • To improve reproducibility and efficiency in microtia reconstruction.

Main Methods:

  • A standardized technique for stage I microtia reconstruction using frozen cadaveric rib cartilage.

  • Utilized in-house designed 3-dimensional, interlocking carving templates to guide framework geometry and subunit proportionality.
  • Preoperative framework production followed by established implantation principles.

    • Main Results:

    • Template-guided construction ensured consistent auricular subunit reproduction.
    • The interlocking design simplified framework planning and assembly.
    • Allogeneic cartilage use eliminated donor-site morbidity and reduced operative time, with wider frameworks aiding skin coverage.

    Conclusions:

    • A novel 3D interlocking template technique offers an efficient alternative to manual carving for auricular framework construction.
    • Allogeneic cartilage is proposed as a viable option in the auricular reconstructive ladder.
    • This approach provides a biological reconstructive pathway, avoiding autologous harvest morbidity and alloplastic risks.
