坚强内固定在口腔颌面部粉碎性骨折治疗中的应用

Use of rigid internal fixation in treatment of oral and maxillofacial comminuted fracture

目的:评价坚强内固定在颌面部粉碎性骨折治疗中的应用价值。方法:选择2004年7月—2007年6月收治的口腔颌面部粉碎性骨折患者79例,男45例,女34例,年龄9～69岁。下颌骨骨折11例,眶-颧复合体骨折31例,上颌骨骨折37例。常规手术进路,切开复位,应用钛板进行坚强内固定。结果:79例患者面形明显改善,77例患者咬合关系恢复正常;2例开,经进一步治疗恢复正常咬合。结论:应用切开复位,于颌骨张力线或应力线或颌面支柱处进行坚强内固定,恢复咬合关系和面部轮廓,并配合微型接骨板复位移位骨片,治疗口腔颌面部粉碎性骨折的效果可靠。

PURPOSE： To evaluate the usefulness of rigid internal fixation in management of oral and maxillofacial comminuted fracture. METHODS： 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. RESULTS： 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. CONCLUSION： Occlusal relation and facial contour can be corrected with rigid internal fixation in tension-line , stress-line or maxillofacial pillars with acceptable outcomes.
