A Guide to High-Density Porous Polyethene Ear Reconstruction

Auricular reconstruction is essential for restoring facial symmetry and achieving a well-contoured, natural-appearing ear. Traditional methods using autologous costal cartilage often delay reconstruction until around age 10, when sufficient rib cartilage is available, which can pose physical and psychological challenges for pediatric patients. Porous high-density polyethylene (PHDPE) implants offer significant advantages, including the ability to perform reconstruction earlier, reduced morbidity, improved ear definition, and the possibility of a single-stage outpatient procedure. On the basis of over 35 years of experience and more than 2500 cases, we present our preferred operative technique for PHDPE ear reconstruction. Careful patient selection, preservation of vascularized fascia, and meticulous flap design are critical to achieving optimal outcomes. The superficial temporoparietal fascia (TPF) flap, along with full-thickness skin grafts, provides reliable and durable implant coverage. In cases where the TPF is unavailable, regional or free vascularized fascia flaps can be used. Additional considerations include preoperative hearing evaluation and the option for simultaneous hearing rehabilitation. For patients with facial asymmetry, fat grafting is a valuable adjunct to improve facial balance while deferring skeletal surgery until maturity. While alloplastic reconstruction offers several benefits, including early intervention and excellent aesthetic outcomes, it requires meticulous surgical planning to minimize the risk of implant exposure. On the basis of our experience, PHDPE ear reconstruction in young children provides safe, durable, and highly satisfactory results with minimal psychological impact.
