Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Regenerative Medicine

Background:

  • Microtia reconstruction presents challenges in achieving natural ear aesthetics.
  • Existing methods often have limitations in terms of complexity and outcomes.

Purpose of the Study:

  • To present an enhanced two-flap surgical technique for microtia reconstruction.
  • To evaluate the efficacy and aesthetic outcomes of this improved method.

Main Methods:

  • A staged approach involving subfascial tissue expansion in the mastoid region for 5 months.
  • Creation of vascularized anteriorly based skin and fascial flaps.
  • Placement of a 3D autogenous rib cartilage framework between flaps.
  • Shaping of specific auricular structures and external auditory meatus mimicry.

Main Results:

  • Successfully reconstructed 146 cases of microtia.
  • Achieved consistently favorable aesthetic results in most patients.
  • Reported minimal major complications, indicating a safe and effective procedure.

Conclusions:

  • The improved two-flap method effectively combines gradual tissue expansion with flap techniques.
  • This integrated approach offers significant advantages for microtia reconstruction without inherent disadvantages of individual methods.
