case_images: There were massive lower face defects due to the loss of 21 cm of mandibular bone, its overlying soft tissue, the entire lower lip, the oral floor, and the lower surface of the anterior third of the tongue (Figure 1A). The head and neck computed tomography (CT) scan relieved subtotal mandibular destruction (Figure 1B). After general anesthesia, resuscitation with one litter of normal saline, antibiotic therapy, and blood products was initiated, then initial debridement and approximation of the lower face defect edges and tracheostomy were performed as initial emergency procedures (Figure 1C).

case_images: Then, the bone and soft tissue and skin defects were estimated (21 cm for bone and 15x6 cm for skin and soft tissue) (Figure 2A). Design and mark OCFFF at the patient s right leg with bone length 21 cm, skin paddle 18x7 cm with aids of hand Doppler ultrasonography which was used to evaluate the site of skin perforators (Figure 2B). The OCFFF was harvested in the standard procedure described by Hidalgo (Figure 2C).

case_images: Five months later, the dental implantation was done for the lower jaw over the OCFFF (Figure 4).
