Abstract

Abstract: Objective: To evaluate the effect of rigid external distractor (RED) in the treatment of old maxillary fractures. Methods: A total of 8 cases of old maxillary fractures were treated in this study, aged from 16 to 45 years (mean 28 years) Application of RED after Le Fort I osteotomy . Distraction rhythm and rate was 0.5 mm twice a day. RED were removed at 4-5 months after distractions. Results: After distraction osteogenesis, patients resumed satisfied facial contour and occlusion. Conclusion: RED is an effective method in treatment of old maxillary fracture.

Key words: districation osteogenesis, rigid external distractor (RED), old maxillary fracture

摘要： 目的：探讨外置式牵引器在陈旧性上颌骨骨折治疗中的应用。方法：应用外置式牵引器治疗8例（年龄16~45岁，中位年龄28岁）陈旧性上颌骨骨折患者，上颌骨Le Fort I型截骨术后安装牵引器，每日牵引1 mm，分2次完成，牵引结束后固定4~5个月拆除牵引器。结果：经牵引成骨后，患者面型及咬合关系得到改善。结论：应用外置式牵引器牵引成骨是治疗陈旧上颌骨骨折的有效方法，且安全、简便，术后稳定性好，值得推广。
