Area of Science:

Plastic Surgery
Otolaryngology
Regenerative Medicine

Background:

Congenital microtia requires surgical reconstruction, with autologous costochondral cartilage being a primary method.
Existing techniques aim for aesthetic and durable ear reconstruction but face challenges in outcome evaluation.

Purpose of the Study:

To review literature on microtia reconstruction using autologous costochondral grafts.
To present and discuss the evolution of a specific surgical technique over 20 years.
To optimize ear reconstruction by minimizing donor site morbidity and enhancing aesthetic outcomes.

Main Methods:

Literature review of microtia reconstruction techniques.
Description of a refined autologous costochondral graft technique utilizing a stacked framework.
Focus on augmenting the antihelical fold and antitragal-tragal complex for improved form.

Main Results:

The presented technique aims for durable and natural-appearing ear reconstruction.
Challenges in objective aesthetic outcome assessment persist due to a lack of universally accepted measures.
Ongoing research in tissue engineering, 3D modeling, and validated questionnaires is crucial.

Conclusions:

Autologous costochondral reconstruction remains a cornerstone for microtia repair.
Continuous refinement of surgical techniques and objective outcome assessment are vital for improving results.
Future advancements in technology and validated assessment tools are expected to enhance aesthetic outcomes.
