Successful Reconstruction of Agnathia by Intraoral Expansion and Free Vascularized Fibula Flap

A successful surgical reconstruction case of a 9-year-old boy with agnathia is presented. The reconstruction was preceded by intraoral expansion of the oral lining and submandibular skin. Four months after initiation of the expansion, the mandible was reconstructed by free vascularized fibula osteocutaneous flap. The 14.5 cm segment of harvested fibula was osteotomized in 4 places to build a replica of the mandible with 3 cm ascending ramus, 3.5 cm body and 1.5 cm symphysis, fixated by titanium micro plating system. The reconstructed mandible was placed between the expanded oral lining and the submandibular skin, with its condylar head placed under the glenoid fossa. After reconstruction, he looked more natural with a chin projection, which he never had. His mother was very happy to see his son being able to show his feeling with facial expression. At last follow-up, he is 14 years and 10 months old, 5 years and 2 months after surgery leading a happy life with his family.
