    Area of Science:

    • Plastic Surgery
    • Biomaterials Engineering
    • Otolaryngology

    Background:

    • Ear reconstruction traditionally uses autologous rib cartilage, which involves significant donor site morbidity.
    • Existing methods can lead to suboptimal aesthetic outcomes and require multiple surgical stages.
    • Early reconstruction is often desired for psychological and social well-being.

    Purpose of the Study:

    • To describe a surgical technique for ear reconstruction utilizing porous polyethylene as the framework.
    • To compare the outcomes of porous polyethylene reconstruction with traditional rib cartilage grafting.
    • To highlight the advantages of porous polyethylene in terms of aesthetics, surgical efficiency, and patient experience.

    Main Methods:

    • Utilizing porous polyethylene as a prefabricated framework for the reconstructed ear.
    • Employing a temporoparietal fascia flap for vascularization.
    • Covering the framework with a full-thickness skin graft.
    • Comparing outcomes with historical data from rib cartilage reconstructions.

    Main Results:

    • Porous polyethylene provides superior definition, projection, and symmetry compared to rib cartilage.
    • Shorter hospitalization periods were observed with the polyethylene technique.
    • Fewer surgical interventions are required, eliminating the need for rib cartilage harvesting and associated complications.
    • Reconstruction can be performed at an earlier age.

    Conclusions:

    • Porous polyethylene is an effective and advantageous material for ear reconstruction.
    • This technique offers improved aesthetic results and a streamlined surgical process.
    • The method minimizes patient morbidity and allows for earlier intervention in cases of microtia.
