In preprosthetic surgery the autologous bone is universally considered the gold standard. Calvaria is, among many options, one of the preferred for its unique characteristics of hardness, easy of harvest and very low morbidity at donor site. Moreover, it gives the possibility of harvesting the pericranium. This technique, recently introduced in common practice in Milan, allows to harvest a large quantity of periosteum to cover bone grafts perioperativly. Periosteal tissue is used to cover bone grafts for two reasons. First, it would provide a layer of tissue that, thanks to its osteogenic potential, would prevent bone resorption. Second, this would interpose a layer of soft tissue to act as a cushion between the bone and mucosal flap to minimize the risk of wound dehiscence, that would bring to bone exposure and consequent failure of reconstruction. Five jaw reconstructions were performed with autologous bone and pericranium. In all cases the outcome was good, the grafts took with correct bone volume preservation. Implants were positioned according to prosthetic needs. In one case a vascular necrosis of a mucosal flap occurred. Bone exposure was prevented by the periosteum, which was revascularized after few days, allowing bone integration. Considering its potential protective capability towards bone grafts and the lack of donor site morbidity, this technique should be considered as a standard procedure in preprosthetic reconstructive surgery.
