Introduction: We aim to evaluate the survival of microvascular free flaps for mandibular defects in craniofacial surgery. Material and methods: We conducted a retrospective study among 178 cases. They type of the defect and the flap used were registered. The complications, survival and the Functional and aesthetic assessments were compared. The p<0.05 was deliberated significant. Results: The rate of total flap necrosis involving the ilium and fibula was significantly higher than that of all other materials combined (p < 0.05). Regarding deglutition statistical analysis between pairs of soft-tissue-defect groups revealed there were significant differences (p < 0.05) between the none and the mucosal groups and also between the none and the through-and-through groups. Regarding speech, there was a significant difference (p < 0.05) between the none and the through-and-through groups. Regarding contour, there were significant differences (p < 0.01) between the none and the through-and-through groups and between the mucosal and the through-and-through groups. No significant difference was seen in the survival of the various flaps. Conclusion: We propose thatwhen the bony defect is lateral, the ilium, fibula, or scapula should be chosen as the donor site, depending on the extent of the soft-tissue defect. When the bony defect is anterior, the fibula is always the best choice. When the soft-tissue defect is extensive or through-and-through with an anterior bony defect, the fibula should be used with other soft-tissue flaps.
