摘要
【目的】探讨牵引成骨术在治疗青少年下颌骨畸形中的效果。【方法】1例半侧颜面发育不全导致小下颌畸形、4例颞下颌关节强直伴小下颌骨畸形患者的患侧植入牵张器,共6处植入牵张器,比较牵引成骨术前后的患者面部外形及相关症状的变化。【结果】5例病例(6个牵引器)按预期完成牵引,牵引完成后所有患者面部畸形得到明显改善,下颌骨牵引延长17.6~28.0mm,平均23.4mm,牵引区形成骨形态和质地理想,症状改善。【结论】牵引成骨术技术在矫治青少年下颌骨发育性畸形中具有重要的临床价值,值得推广。
[Objective] To explore the effect of distraction osteogenesis (DO)in the treatment of juvenile mandibular deformity. [Method ] Five cases of juvenile patients with micrognathia deformity,which 1 case caused from hemifacial microsomia and 4 cases from ankylosis, were treated with distraction osteogenesis, 6 distractors were fixed, the changes of facial appearance and relative symptoms were compared preoperatively and postoperatively. [Result] DO have been finished, the facial deformity of all patients were corrected, the average distraction distance on the affected side reached 23.4 mm (range 17.6 nun to 28.0 nun) after distraction, the relative symptoms were minimized. Expected appearance and quality of bone formation in the gaps achieved. [ Conclusion ] DO is a feasible method in the treatment of juvenile mandibular deformity, it is worthy of recommending widely.
