We describe our method for reconstructing microtic auricles using a porous polyethylene framework in two stages. The first stage of the procedure involves rotating a superficial temporoparietal fascial (TPF) flap over the framework. The inferior two-thirds of this framework is next inset into a local temporal skin pocket, while the superior one-third is covered with a full thickness skin graft from the contralateral postauricular sulcus. Lobular transposition is commenced in a second stage procedure at the three-month postoperative period. Hearing restoration surgery is encouraged at a later date in selected patients with unilateral microtia. Use of the porous polyethylene framework permits a more expedient, less invasive, and more reliable method for auricular reconstruction than does the traditional method that employs costal cartilage.
