To evaluate the incidence and risk factors of the temporomandibular joint disorders (TMD) in the patients suffering from maxillo-facial injury without condylar fractures.
sixty patients without condylar fractures were recruited from Feb 2014 to Nov 2015 in the department of stomatology, Lishui people's hospital. The incidence of TMD was recorded at 1, 3, 6, 9 and 12 months after injury through MRI examination. The risk factors for TMD were evaluated by logistic regression analysis.
the TMD incidence rates were 25.0%, 30.0%, 35.0%, 41.7% and 48.3% at 1, 3, 6, 9 and 12 months after injury with no statistical difference between male and female (P>0.05). Logistic regression indicated that disorder of occlusal relationship (OR=1.84,95%CI:1.36-2.78) and hemi-mastication (OR=1.56, 95% CI:1.23- 2.24) were independent risk factors for the development of TMD.
there was a high incidence of temporomandibular joint disorders in the patients suffering from maxillo-facial injury without condylar fractures. The disorder of occlusal relationship and hemi-mastication were independent risk factors for the development of post-injury TMD.
评估无髁突骨折的颌面部损伤患者颞下颌关节紊乱病（TMD）的发生率及危险因素。
选取2014年2月至2015年11月在丽水市人民医院口腔科就诊的60例无髁突骨折患者。通过MRI检查记录伤后1、3、6、9和12个月时TMD的发生率。采用logistic回归分析评估TMD的危险因素。
伤后1、3、6、9和12个月时TMD的发生率分别为25.0%、30.0%、35.0%、41.7%和48.3%，男女之间无统计学差异（P>0.05）。logistic回归分析表明，咬合关系紊乱（OR=1.84，95%CI：1.36-2.78）和偏侧咀嚼（OR=1.56，95%CI：1.23-2.24）是TMD发生的独立危险因素。
无髁突骨折的颌面部损伤患者中颞下颌关节紊乱病的发生率较高。咬合关系紊乱和偏侧咀嚼是伤后TMD发生的独立危险因素。
