Mandibular reconstruction using the double barrel fibular graft.
Five patients underwent mandibular reconstruction using the double barrel fibular graft from 1989 to 1994. Bony defects ranged from 7 to 14 cm. In three patients, two skin flaps were taken with the fibular graft for composite reconstruction. In order to overcome the main disadvantage of the fibular graft, i.e., small circumference of the bone, a harvested fibula was osteotomized into several portions, folded into two parallel lengths, and fixed along the inferior border of the mandible and the alveolar ridge. The double barrel fibular graft provided more than 4-cm alveolar height without damaging bone viability. In Orientals, a fibula is approximately 1.5 cm thick, and using a single fibular strut for mandibular reconstruction may result in subsequent difficulty in wearing conventional dentures or osseointegrated implants. All patients acquired good mandibular contour and enough thickness of the alveolar ridge, and could wear a conventional denture and eat a solid diet. This procedure seems to be superior to the iliac bone graft for major mandibular reconstruction because of its length, the possibility of three-dimensional composite reconstruction, increased bone thickness, and minimal donor-site morbidity.
