摘要
目的分析可复性与不可复性颞下颌关节盘前移位MRI征象,为准确诊断颞下颌关节紊乱病(TMD)提供有价值的参考。方法随机选取2022年1月至2024年4月在信阳市中心医院就诊的临床诊断为TMD并且经过颞下颌关节磁共振扫描的患者,对其中MRI表现为颞下颌关节盘前移位的病例进行研究,共选取152侧(男性32侧,女性120侧),年龄10~72岁。分关节盘可复性前移位组(DDWR)(69侧)和关节盘不可复性前移位组(DDWoR)(83侧),观察关节盘移位侧别(左、右),颞下颌关节髁突形态(卵圆形、扁平形及鸟嘴形)及是否增生,关节盘类型(双凹型、后带增厚型、前带增厚型、拉伸型、折叠型、结节型),是否有侧方移位(内侧、外侧),关节活动度(正常、受限、过度),关节是否有积液。结果DDWR和DDWoR组间对比,下颌骨髁状突是否增生、关节盘侧方移位、关节盘形态、颞颌关节活动度差异有统计学意义(P<0.05);两组间性别、年龄、侧别、下颌骨髁突形态、关节腔有否积液差异无统计学意义(P>0.05)。结论TMD DDWR和DDWoR组间对比,下颌骨髁状突是否增生、关节盘侧方移位、关节盘形态、颞颌关节活动度MRI表现有显著不同。
Objective To provide a valuable reference for accurate diagnosis of temporomandibular disorders(TMD)by analyzing MRI signs related to reducible and irreducible anterior disc displacement of the temporomandibular joint.Methods Patients clinically diagnosed with TMD and undergoing MRI of the temporomandibular joint at Xinyang Central Hospital from January 2022 to April 2024 were randomly selected.Cases with MRI manifestations of anterior disc displacement of the temporomandibular joint were studied,resulting in a total of 152 sides(32 male and 120 female),aged 10-72 years.They were divided into the reducible anterior disc displacement with reduction group(DDWR)(69 sides)and the disc displacement without reduction group(DDWoR)(83 sides).Observations were made on the side of disc displacement(left or right),the morphology of the temporomandibular joint condyle(oval,flat,and beak-shaped)and the presence of hyperplasia,the type of disc(biconcave,posterior band thickened,anterior band thickened,stretched,folded,and nodular),the presence of lateral displacement(medial or lateral),joint mobility(normal,limited,or excessive),and the presence of joint effusion.Results When comparing the DDWR and DDWoR groups,there were statistically significant differences in the hyperplasia of the mandibular condyle,lateral displacement of the disc,disc morphology,and temporomandibular joint mobility(P<0.05).There were no statistically significant differences between the two groups in terms of gender,age,side of displacement,mandibular condyle morphology,and the presence of joint effusion(P>0.05).Conclusion MRI findings of hyperplasia of the mandibular condyle,lateral displacement of the disc,disc morphology,and TMJ mobility showed significant differences between the DDWR and DDWoR groups in patients with TMD.
