Trifocal distraction osteogenesis for reconstruction of skull defect

ObjectiveTo apply trifocal distraction osteogenesis in canine model of skull segmental defects and to provide reference for clinical treatment.MethodsSix labrador dogs were selected in this study and divided into observation group and control group randomly. Each group contained 3 dogs. Skull segmental defects models were established by surgery, and dogs in bservation group received trifocal distraction osteogenesis treatment. Bone density was observed and compared between two groups during treatment.ResultsThere were no significant difference in bone density between two groups on th 1st day (P>0.05). The bone density of observation group on the 30th day, and 60th day were higher than that of control group (P<0.01).ConclusionsTrifocal distraction osteogenesis has significant clinical effect, and it would be widely used in clinical treatment.
