Summary
This study presents a novel surgical technique for reconstructing large helical rim defects using bilateral chondrocutaneous flaps. The method ensures excellent cosmetic results with minimal ear circumference loss and low patient morbidity.
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.
