The effect of hyperbaric oxygen therapy on vertical distraction osteogenesis procedure according to consolidation periods has been determined. Hyperbaric oxygen therapy may increase the quality and the quantity of bone and shorten the consolidation period.

The results of this study indicate that PD with HBO could be used to increase the quality and the quantity of the bone newly formed by PD.

We designed one-and-a-half-barrel vascularized free fibular flap which is a further modification of the double-barrel technique, and we tried to overcome the discrepancy between mandible and fibula flap. We used this flap in case of a segmental mandibular defect that occurred as a result of a giant cell reparative granuloma excision. This new modification eliminated volume insufficiency of the classical technique and volume excess of the double-barrel technique.A segmental mandibular defect that occurred as a result of giant cell reparative granuloma excision was reconstructed using one-and-a-half-barrel vascularized free fibular flap. The size discrepancy between mandible and free fibula flap is a well-known problem, and this new modification of free fibular flap eliminated volume insufficiency or excess problems of the other techniques.
