Introduction: Porous polyethylene (PPE) has been used successfully for craniofacial augmentation
and auricular reconstruction. This inert material offers reliable projection and definition
and reduced operative time, permitting earlier auricle reconstruction. Tissue engineered
auricular cartilage would obviate the current need for costal grafting and its associated
morbidity; however it currently lacks biomechanical strength. We propose a composite
construct as a model for the tissue engineered auricle, combining the advantages of
tissue engineering and alloplast technology. We postulate that PPE could be used as
an endoscaffold to support the growth of tissue engineered cartilage and enhance the
mechanical properties and morphology of the engineered auricle.
