目的探讨前方牵引器、吊颌帽在上颌骨嵌入性骨折复位固定中的疗效及临床实用性。方法选择开封市第一人民医院2006-2011年收治的28例嵌入性上颌骨骨折患者,应用前方牵引器行上颌骨前方牵引,到位后行颌间牵引复位咬合关系,再行吊颌帽颅颌固定。结果新鲜骨折经过3～5d前方牵引均能达到较为理想的咬合关系,陈旧性骨折经1～2周牵引亦能达到较为理想的咬合关系,再经颌间牵引3～7d,咬合关系进一步改善,吊颌帽颅颌固定3～4周骨折初步愈合,均达到较为理想的咬合关系及面部外形。结论前方牵引器、吊颌帽应用于上颌骨嵌入性骨折复位固定效果较好,方法简便,无需手术,但需注意牵引的方向及牵引力的调节。
Objective To investigate the curative effect and clinical practicability of anterior distractor and maxillary cap in the reduction and fixation of maxillary impacted fractures. Methods 28 patients with embedded maxillary fractures admitted in the First People’s Hospital of Kaifeng City from 2006 to 2011 were treated with anterior traction device to pull the maxillary anterior traction and then underwent intermaxillary traction and reduction occlusion, fixed. Results The fresh fractures reached the ideal occlusal relationship after 3 ~ 5 days of traction, and the old fractures reached the ideal occlusion after 1 ~ 2 weeks of traction. After intermaxillary traction for 3 ~ 7 days, the occlusal relationship was further improved, Cranial jaw cap cranial fixation 3 to 4 weeks fracture healing, have reached a more ideal occlusal relationship and facial appearance. Conclusion The frontal traction device and maxillary cap should be used in the reduction and fixation of maxillary impacted fractures. The method is simple and requires no surgery. However, attention should be paid to the direction of traction and the regulation of traction.
