Abstract: Objective: To evaluate the clinical effect of mandibular reconstruction used vascularized iliac crest and fibular flap, and to compare their advantages and disadvantages. Methods: We conducted a retrospective analysis of 44 patients who underwent mandibular reconstruction, 20 patients with iliac crest and 24 with free fibula. The results of contour and function, complications of recipient and donor sites were analyzed according to the clinical data and follow-up. Results: All flaps survived. There was no significant difference for contour and function between the vascularized iliac crest flap and free osteofasciocutaneous fibula flap, but the length of graft bone had significant discrepancy between iliac crest and fibula. Conclusion: The two graft bones could meet the needs of the various types of mandibular defects, but it must have an option for the different site and range of mandibular defect and soft tissue defect between iliac crest flap and fibular flap. For defect whose length was less than 8cm, priority can give to iliac bone, but for defect greater than 8cm fibula flap should choose.
