[Reconstruction of the floor of the auricle in congenital microtia in children].

The data are presented on 329 children (201 boys and 128 girls) with congenital defects of the external and middle ear. Right-side defect occurred twice as frequently as left-side one. Treatment in 45 children with bilateral defects started with reconstructive meatotympanoplasty. Surgical reconstruction has been performed on 106 floors of the auricle. In 51 cases a rib homocartilage and free skin were used (group 1), in 55 cases alloplastic frames were covered with pedicle tissue (group 2). The following complications occurred in group 1: a complete resorption of the cartilage, necrosis of the skin graft, decubitus (5, 5 and 6 cases, respectively). In group 2 there were 5 cases of the pedicle necrosis, 7 cases of the pedicle self-detachment, 7 cases of the frame sequestration, 2 cases of late frame displacement. The floors formed with the use of neck-chest pedicle and compound silicone frame produced the best cosmetic effects.
