Reconstruction of skull defect by means of transport distraction osteogenesis with the aid of guided tissue regeneration method.

本研究的目的是通过运输牵张成骨重建颅骨缺损。基于“引导组织再生法”，我们计划用兔颅骨进行实验研究。兔颅骨进行运输牵张成骨，牵张部位用e-PTFE膜覆盖。在我们的假设中，再生骨不受周围软组织的干扰，因此新骨的质量应优于无膜牵张再生骨。然而，再生骨的测量值并不大于常规无膜牵张法的再生骨。

This study was aimed to reconstruct a skull defect by means of transport distraction osteogenesis. Based on "guided tissue regeneration method", we planned experimental study using rabbit skull. Transport distraction osteogenesis was performed on rabbit skull and the distraction site was covered with e-PTFE membrane. In our hypothesis, regenerate bone was not disturbed by surrounded soft tissue so that quality of new bone should be better than the regenerate that made by distraction without membrane. However, measurement of regenerate bone was not greater than regenerate made by conventional distraction without membrane.
