The aim of this study was to investigate the clinical characteristics of disc perforation (DP) of temporomandibular joint (TMJ) at different ages. METHODS：Patients with TMJ disc perforation admitted to the Department of Trauma and Temporomandibular Joint Surgery Stomatological Hospital of Wuhan University, from April 2012 to May 2021 were included in this study. They were divided into 6 groups according to different ages. Clinical and CBCT radiographic features were analyzed. Clinical features included maximal interincisal opening, pain, clicking，and occlusal changes. Imaging features included condylar absorption flattening, hyperplasia or osteophyte formation, sclerosis, subchondral cysts, depression defects, and blurred anterior slope. The clinical and imaging characteristics of patients in different age groups were statistically analyzed. SPSS 26.0 software was used for statistical analysis, and Chi-square test was used to compare the distribution of clinical symptoms and imaging features in patients of different ages.
A total of 368 patients were collected, including 24 males, with an average age of 27.63±15.90 years. There were 344 females with an average age of 32.61±15.61 years. The incidence of pain was 21.31%, occlusal change was 50.82%, and condylar absorption flat was 50.82% in the 10-19 age group. The incidence of pain in 20-29 age group was 31.06%, occlusal change was 53.42%, and condylar absorption flattening was 45.34%. In 50-59 age group, the incidence of pain was 83.33%, occlusal changes were 2.38%, and hyperplasia or osteophyte formation was 47.62%. In age group ≥60 years old, the incidence of pain was 82.86%, occlusal changes were 2.86%, and hyperplasia or osteophyte formation was 60%.
In terms of clinical features, patients under 40 years old are more likely to have occlusal changes, while patients over 40 years old are most likely to have joint pain. Radiographically, patients under 40 years old are mainly characterized by bone loss in the condyle, while patients over 40 years old are mainly characterized by condylar hyperplasia.
本研究旨在探讨不同年龄段颞下颌关节盘穿孔（DP）的临床特征。方法：纳入2012年4月至2021年5月在武汉大学口腔医院创伤与颞下颌关节外科住院的颞下颌关节盘穿孔患者。根据不同年龄分为6组，分析其临床及CBCT影像学特征。临床特征包括最大切牙间开口度、疼痛、弹响及咬合变化。影像学特征包括髁突吸收变平、增生或骨赘形成、硬化、软骨下囊肿、凹陷缺损及前斜面模糊。对不同年龄组患者的临床及影像学特征进行统计学分析。采用SPSS 26.0软件进行统计分析，用卡方检验比较不同年龄患者临床症状及影像学特征的分布情况。
共收集368例患者，其中男性24例，平均年龄27.63±15.90岁；女性344例，平均年龄32.61±15.61岁。10 - 19岁年龄组疼痛发生率为21.31%，咬合变化发生率为50.82%，髁突吸收变平发生率为50.82%。20 - 29岁年龄组疼痛发生率为31.06%，咬合变化发生率为53.42%，髁突吸收变平发生率为45.34%。50 - 59岁年龄组疼痛发生率为83.33%，咬合变化发生率为2.38%，增生或骨赘形成发生率为47.62%。≥60岁年龄组疼痛发生率为82.86%，咬合变化发生率为2.86%，增生或骨赘形成发生率为60%。
在临床特征方面，40岁以下患者更易出现咬合变化，40岁以上患者最易出现关节疼痛。在影像学方面，40岁以下患者主要表现为髁突骨质流失，40岁以上患者主要表现为髁突增生。
