title: [Porous polyethylene implants for ear reconstruction of middle to high-grade ear defects].
abstract: The incidence of middle to high-grade ear malformations in Germany is approximately 150 per year. For many years autologous rib cartilage has been used for ear reconstruction as a framework material. In spite of a good biocompatibility of autologous rib cartilage there are potential risks of framework deformity as well as donor site morbidity. The advantages of osseo-integrated implants have provided patients with predictable esthetic results, durability and improved retention of the ear prostheses. Porous polyethylene ear implants (Medpor®) have been used for over 20 years as a suitable framework material. The advantages of this promising technique are good biocompatibility, short hospitalization time and the possibility of a one-step reconstruction of total or subtotal ear defects. The reconstruction of ear malformations with porous polyethylene ear implants is possible even in patients over 6 years old. Moreover, polyethylene promotes revascularization due to its porous structure, resulting in a good incorporation at the implantation site. The use of porous polyethylene ear implants permits a more expedient, less invasive and reliable reconstruction in moderate or high-grade ear malformations with very convincing results.
