    Summary

    Microtia reconstruction uses staged autogenous cartilage grafting for improved outcomes. This approach addresses the complex congenital ear deformity, minimizing psychological impact on children.

    Area of Science:

    • Plastic Surgery
    • Congenital Deformities
    • Otolaryngology

    Background:

    • Microtia is a rare congenital ear deformity affecting 1 in 7000–8000 births.
    • This condition can cause significant psychological distress in affected children.
    • Reconstructing microtia presents a major challenge for surgeons.

    Purpose of the Study:

    • To describe a staged surgical technique for microtia reconstruction.
    • To highlight the benefits of autogenous cartilage framework placement.
    • To emphasize avoiding middle ear and external canal reconstruction when hearing is normal contralaterally.

    Main Methods:

    • A staged reconstruction process, beginning at age 5.
    • Placement of an autogenous cartilage framework in the first stage.
    • Lobule rotation, conchal depression formation, tragal reconstruction, and helical rim elevation in subsequent stages.
    • Utilizing a thin skin flap over the framework for enhanced definition and coaptation.

    Main Results:

    • Maturing techniques based on Tanzer and Brent's work yield consistently good results.
    • The staged approach helps avoid problems associated with the deformity.
    • Maximal use of non-scarred elastic skin during the first stage facilitates lobule splicing.
    • Thin skin flaps contribute to preventing late framework deformation.

    Conclusions:

    • Staged reconstruction with autogenous cartilage is effective for microtia.
    • The technique optimizes aesthetic outcomes and minimizes complications.
    • Careful surgical planning is crucial for successful microtia repair.
