摘　　要：目的探讨外伤后无髁状突骨折的颞下颌关节紊乱(TMD)的发生率及其危险因素。方法选取颌面部外伤且无髁状突骨折患者60例为研究对象,采用颞下颌关节MRI及常规口腔颌面部检查对患者伤后进行随访,并记录患者伤后1月、3月、6月、9月及12月TMD发生率;采用Logistic回归方法探讨影响伤后12个月TMD发生的危险因素。结果入组60例患者伤后随访1年,伤后1月、3月、6月、9月及12个月TMD发生率分别为25.0%,30.0%,35.0%,41.7%和48.3%,男女发病率无统计学差异(P<0.05);Logistic回归分析显示,咬合关系紊乱(OR=1.84,95%CI∶1.36-2.78)及偏侧咀嚼(OR=1.56,95%CI∶1.23-2.24)是TMD发生的独立危险因素。结论外伤后无髁状突骨折的TMD发生率较高,合并咬合关系紊乱及偏侧咀嚼患者TMD发生率更高。Objective To research the incidence of and risk factors of the temporomandibular joint disorders in patients without condylar fractures.Methods 60 patients who had Maxillofacial injuries but without condylar fractures were taken as research subjects. Subjects＇ TMD inci- dences were evaluated 1,3,6,9 and 12 months after injuries by taking temporal-mandibular joint MRI and regular oral and maxillofacial region inspection.Also risk factors of TMD were evaluated by logistic regression analysis 12 months after injury.Results In one year follow-up studies,the TMD incidence rates among the 60 patients were 25.0%,30.0%,35.0%,41.7% and 48.3% respectively for 1,3,6,9 and 12 months after injury and there was no statistical difference between male and female（P〈0.05）.Logistic regression analysis indicated that occlusion relationship disorder （OR= 1.84,95% CI ： 1.36-2,78） and side chewing（ OR= 1.56,95%CI ： 1.23- 2. 24） were the independent risk factors for TMD.Conclusion There was a high incidence of TMD in patients without condylar fractures,and there was higher incidence of TMD in patients with occlusion relationship disorder and side chewing.
