This study presents a safe and reliable two-stage surgical method for total auricle reconstruction in patients with congenital microtia. The technique utilizes autologous costal cartilage, achieving satisfactory ear shapes and steady auriculocephalic angles in most cases.

Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Regenerative Medicine

Context:

  • Congenital microtia presents significant aesthetic and functional challenges.
  • Previous auricular reconstruction methods have limitations in achieving natural form and symmetry.

Purpose:

  • To evaluate a two-stage surgical technique for total auricle reconstruction using autologous costal cartilage.
  • To assess the safety, reliability, and aesthetic outcomes of this auricular reconstruction method.

Summary:

  • A two-stage surgical approach was employed for 101 ears in 90 patients with congenital microtia.
  • The first stage involved creating a costal cartilage framework and embedding it, followed by auriculocephalic sulcus creation in the second stage.
  • Outcomes included high rates of satisfactory ear shapes, with minor complications such as partial flap necrosis and framework exposure.
