Vertical distraction osteogenesis of fibular bone flap in reconstructed mandible.
Excellent functional and aesthetic results can be achieved in mandibular reconstructions with using free fibular bone flap. However, the vertical deficiency between the reconstructed segment and the occlusal plane made dental rehabilitation impossible in some cases. We encountered this problem in our 3 patients who had mandibular reconstruction with fibular flap due to extensive bone defect result from gunshot injury. To overcome this segmental vertical distraction of the reconstructed mandible was performed. Fibular bone segments (40-70 mm) were distracted with using extraoral distraction device after a latency period of 5-7 days. The rate of distraction was 1 mm/day, and the rhythm was 4 times (4 x 0.25 mm). Distraction was continued until the desired height was achieved, and the distractor left in place for 12 weeks for bony consolidation. No minor or major complications were encountered. The increase of vertical height was between 9 and 13 mm, and it was stable during the follow-up period (7-22 months). Following the vertical distraction and vestibuloplasty operations, the dental restoration of the patients was performed with mandibular removable partial dentures.
