摘要

Unidirectional lengthening is one of the main problems of distraction osteogenesis when treating mandibular defects. In order to solve the problem, multi-directional distractors have evolved to better control the distraction vectors. We presented a 22 years old female who was diagnosed as post trauma facial deformity with severe mandibular defects. To reconstruct the under-developed mandible, we applied distraction osteogenesis with the multi-directional device and on the second stage performed orthognathic surgery to achieve better occlusion and function. The facial asymmetry was greatly improved and the patient was satisfied with the results. By this multidirectional device, the desired vectors could be controlled during distraction and therefore better attained esthetic and functional goals.

採用骨牽引手術治療下顎骨缺損時，僅有單一方向的增長被視為一大問題。為了解決這個困擾而發展出多方向的牽引器，以期獲得對牽引方向更佳的掌控。本報告提出案例為一22歲女性，診斷為外傷後導致之顏面畸型合併嚴重下顎骨缺損。為了重建其發育不全之下顎骨，我們採用多方向之骨牽引器，並在第二階段給予正顎手術來改善咬合及功能。術後顏面不對稱之情形獲得顯著的改善，病患亦對結果感到滿意。藉由多方向之牽引器，可在牽引過程掌控理想的方向，因而達到美觀及功能上更好的結果。
