Microtia is a congenital malformation affecting the external ear, with esthetic and psychosocial consequences. Several reconstruction techniques are available, including epithesis, autologous reconstruction with costal cartilage, and alloplastic reconstruction using synthetic implants. The latter enables reconstruction in a single operation, using a porous polyethylene implant and without needing a donor site, and can be performed at a younger age than conventional techniques. The surgical procedure involves placement of the implant, which is covered by a temporal fascia flap and total skin grafts. The results obtained are reproducible and long-lasting, enabling better social integration of microtia patients. Thus, this innovative technique is an effective alternative to traditional methods of auricular reconstruction.
