[Reconstruction of upper and lower jaw defects by microsurgical bone grafting].

Indications for microvascular bone grafts in maxillo-facial surgery are defined. Surgical procedures at the main donor sites for upper and lower jaw reconstructions, vascularized iliac bone grafts and scapular flaps, are described. Applications are demonstrated in various cases. Vascularized growth-plate transplantation for reconstructing hemifacial microsomia introduces new possibilities. Microsurgery is a safe method with a high success-rate (94%) and a low morbidity at the donor site.
