To evaluate the usefulness of rigid internal fixation in management of oral and maxillofacial comminuted fracture.
From July 2004 to June 2007, 79 patients with oral and maxillofacial comminuted fractures (including 45 males, 34 females, aged from 9 to 69 years, 11 mandibular fractures, 31 ZMC fractures, 37 maxillary fractures) were treated with open reduction and rigid internal fixation.
Facial profile in 79 cases and cross-bite in 77 cases were corrected satisfactorily. Cross-bite in 2 cases changed to open bite,and were corrected later with subsequent adjustment.
Occlusal relation and facial contour can be corrected with rigid internal fixation in tension-line, stress-line or maxillofacial pillars with acceptable outcomes.
评估坚固内固定在口腔颌面部粉碎性骨折治疗中的应用价值。
2004年7月至2007年6月，对79例口腔颌面部粉碎性骨折患者（男45例，女34例，年龄9至69岁，下颌骨骨折11例，颧骨复合体骨折31例，上颌骨骨折37例）行切开复位坚固内固定治疗。
79例患者面部外形均获满意矫正，77例患者咬合关系矫正满意。2例患者由反牙合变为开牙合，后期经调整后得到矫正。
采用坚固内固定技术在张力线、应力线或颌面支柱处进行治疗，可有效矫正咬合关系及面部轮廓，效果良好。
