This study aims to analyze the clinical symptoms and imaging manifestations in patients with temporomandibular disorder syndrome (TMD), who are sensitive to sudden temperature drop.
One hundred and nineteen patients with TMD who attended the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital from December 2022 to December 2023 were included, including 44 males and 75 females, with a mean age of 32.4±13.7 years.The questionnaire was used to determine whether they were sensitive to temperature drop, and the TMD patients were divided into a temperature plunge-sensitive group and a temperature drop insensitive group. The clinical symptoms and imaging manifestations of patients in the two groups were observed. SPSS 25.0 was used for statistical analysis.
There was no statistically significant difference between the gender and age of patients in the temperature plunge-sensitive group (50 patients) and the insensitivity group (69 patients) (>0.05). The percentage of patients with pain was slightly higher in the temperature plunge-sensitive group [86.0% (43/50)] than in the insensitive group [68.1% (47/69)], and the difference was statistically significant (=5.031, =0.025), while the differences in joint murmur and mouth opening limitation between the two groups were not statistically significant. A total of 238 lateral joints were detected in both groups, the percentage of osteoarthropathic imaging changes was significantly higher in the temperature plunge-sensitive group [82.0% (82/100)] than in the insensitive group [53.6% (74/138)] (=20.675, <0.001). Magnetic imaging showed that the percentage of joint effusion was higher in patients in the temperature plunge-sensitive group [66.0% (33/50)] than in the insensitive group [42.0% (29/69)], and the difference was statistically significant (=5.602, =0.018).
TMD patients with maxillofacial pain symptoms, joint effusions, and abnormal imaging of osteoarticular structures are more likely to be sensitive to sudden temperature drops.
本研究旨在分析对温度骤降敏感的颞下颌关节紊乱综合征（TMD）患者的临床症状和影像学表现。
纳入2022年12月至2023年12月在中国人民解放军总医院第一医学中心口腔科就诊的119例TMD患者，其中男性44例，女性75例，平均年龄32.4±13.7岁。采用问卷确定患者是否对温度下降敏感，将TMD患者分为温度骤降敏感组和温度下降不敏感组。观察两组患者的临床症状和影像学表现。采用SPSS 25.0进行统计分析。
温度骤降敏感组（50例）和不敏感组（69例）患者的性别和年龄差异无统计学意义（>0.05）。温度骤降敏感组疼痛患者的比例[86.0%（43/50）]略高于不敏感组[68.1%（47/69）]，差异有统计学意义（=5.031，=0.025），而两组间关节杂音和张口受限的差异无统计学意义。两组共检测238个颞下颌关节，温度骤降敏感组骨关节影像学改变的比例[82.0%（82/100）]显著高于不敏感组[53.6%（74/138）]（=20.675，<0.001）。磁共振成像显示，温度骤降敏感组患者关节积液的比例[66.0%（33/50）]高于不敏感组[42.0%（29/69）]，差异有统计学意义（=5.602，=0.018）。
有颌面疼痛症状、关节积液及骨关节结构影像学异常的TMD患者更易对温度骤降敏感。
