Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Reconstructive Surgery

Background:

  • Large defects of the helical crus can result from surgical excisions.
  • Reconstruction of the helical crus requires techniques that restore 3D form, color, and texture.
  • Existing methods may have limitations in achieving satisfactory aesthetic and functional outcomes.

Observation:

  • A helical crus reconstruction technique utilizing a postauricular chondrocutaneous flap, vascularized by postauricular vessels, was applied.
  • The procedure was performed on seven patients with large helical crus defects post-surgery.
  • Flap design was individualized to match the defect's specific form.

Findings:

  • All seven flaps survived without complications, demonstrating successful vascularization.

  • The reconstructed ears exhibited good three-dimensional form with satisfactory color and texture match.
  • The postauricular donor site was concealed, minimizing aesthetic concerns.
  • No instances of constriction, scar contracture deformity, or cartilage absorption were observed.

    • Implications:

    • This postauricular chondrocutaneous flap technique offers a reliable and effective solution for helical crus reconstruction.
    • The method provides excellent aesthetic and functional results, addressing key challenges in ear reconstruction.
    • The technique's low complication rate and favorable donor site concealment enhance its clinical applicability.
