Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Reconstructive Surgery

Background:

  • Large defects of the helical rim present a reconstructive challenge.
  • Existing methods may result in significant cosmetic deformity or loss of ear circumference.

Purpose of the Study:

  • To describe a unique and effective surgical approach for reconstructing large helical rim defects.
  • To evaluate the cosmetic outcomes and morbidity associated with this technique.

Main Methods:

  • A novel technique involving bilateral chondrocutaneous flaps of the helical rim.
  • Incorporation of a semicircular chondrocutaneous excision of the adjacent scapha and antihelix.
  • Surgical reconstruction of large external ear defects.

Main Results:

  • Successful repair of large helical rim defects was achieved.
  • Minimal loss to the overall external ear circumference was observed.
  • Excellent cosmetic outcomes and minimal patient morbidity were reported.

Conclusions:

  • This chondrocutaneous flap technique is a technically simple and reliable method for helical rim defect reconstruction.
  • The approach offers excellent aesthetic results and low complication rates.
  • It is a valuable option for managing large external ear defects.
