Reconstruction of Concha-Type Microtia Using a Delayed Postauricular Skin Flap

Area of Science:

• Plastic Surgery
• Otolaryngology
• Regenerative Medicine

Background:

• Concha-type microtia reconstruction presents challenges in managing the residual auricle.
• A novel approach is needed to effectively reconstruct the auricle while preserving or modifying the existing structures.

Purpose of the Study:

• To describe and evaluate a three-stage surgical technique for concha-type microtia reconstruction.
• To assess the aesthetic outcomes and patient satisfaction using a delayed postauricular skin flap.

Main Methods:

• Retrospective analysis of 40 patients with concha-type microtia undergoing reconstruction.
• A three-stage procedure involving delayed postauricular skin flap preparation, autogenous rib cartilage framework insertion, and final modifications.
• Careful articulation of the framework with retained residual auricular cartilage for seamless integration.

Main Results:

• All 40 reconstructed auricles exhibited good aesthetic appearance.
• A smooth, well-matched junction was achieved between the reconstructed auricle and the residual ear.
• Patients reported high satisfaction with the cosmetic results and scar quality.

Conclusions:

• The described three-stage method using a delayed postauricular skin flap is effective for concha-type microtia reconstruction.
• This technique yields excellent aesthetic outcomes, smooth integration with residual structures, and high patient satisfaction.
• The management of the residual auricle is crucial for successful microtia repair.
