This study introduces a novel method for auricular reconstruction using expanded retroauricular skin flaps. This technique provides sufficient tissue for cartilage frameworks, leading to high patient satisfaction with reconstructed ears.

Area of Science:

  • Plastic Surgery
  • Regenerative Medicine
  • Biomaterials Engineering

Background:

  • Auricular reconstruction often requires sufficient skin coverage for autogenous costal cartilage frameworks.
  • Traditional methods may necessitate skin grafts or fascial flaps, increasing complexity.
  • A new strategy for expanding retroauricular mastoid skin is proposed to address this coverage challenge.

Purpose of the Study:

  • To present a new surgical strategy for auricular reconstruction utilizing expanded retroauricular mastoid skin.
  • To evaluate the efficacy and outcomes of this technique in a series of microtia reconstructions.

Main Methods:

  • The procedure involved three stages: insertion and expansion of a retroauricular skin expander (50ml to 100-120ml).
  • The expanded skin was divided into two flaps (A and B) to envelop a 3D autogenous costal cartilage framework.

  • The third stage included tragus construction and conchal excavation.

    • Main Results:

    • 42 microtia reconstructions were performed between 2000 and 2009.
    • 36 patients reported satisfaction with the reconstructed ear's shape, size, orientation, and detail.
    • Complications included hematoma, partial skin eversion, and partial skin necrosis, all managed appropriately.

    Conclusions:

    • Exceeding expansion of retroauricular skin provides ample non-hair-bearing tissue for auricular cartilage frameworks.
    • This method eliminates the need for skin grafts and retroauricular fascial flaps.
    • Patients are generally satisfied with the aesthetic and functional outcomes of reconstructive auricles.
