To evaluate the post-operative condylar bone remodeling after the treatment of Yang's arthroscopic surgery. Consecutive cases from Jan 2017 to May 2018 that received Yang's arthroscopic surgery were included in this study, the TMJ MRI examinations were performed preoperatively and postoperatively (follow up for 1 year or more), and condylar bone remodeling was estimated. A total of 229 patients (29 male and 200 female) were included in the study, 161 patients had new bone formation, and the average age was 17.5 ± 2.1a. There was no new bone formation in 68 patients with an average age of 24.5 ± 0.7a. The percentage of new bone formation patients in 10-15 years of age was 94.33% and decreases as the age increases. In the position of new bone formation, the posterior slope of condyle was the most (129 joints), the second was the top of condyle (54 joints), the third was around condyle (33 joints), only 25 joints had new bone on the anterior slope of condyle. After TMJ arthroscopic surgery, the condyle has the ability to form new bone, and the younger the age, the stronger the ability of new bone formation. The formation of new bone was most in posterior slope and least in anterior slope of condyle.
评估杨式关节镜手术治疗后髁状骨的术后改建。本研究纳入了 2017 年 1 月至 2018 年 5 月连续接受杨式关节镜手术的病例，所有患者均行 TMJ MRI 检查，分别于术前和术后（随访 1 年以上）进行评估，观察髁状骨改建情况。共纳入 229 例患者（男 29 例，女 200 例），其中 161 例有新骨形成，平均年龄为 17.5±2.1 岁；68 例无新骨形成，平均年龄为 24.5±0.7 岁。10~15 岁患者中新骨形成率为 94.33%，随着年龄增长逐渐降低。新骨形成的位置中，髁突后斜面最多（129 个关节），其次是髁突顶部（54 个关节），再次是髁突周围（33 个关节），仅 25 个关节在前斜面有新骨形成。TMJ 关节镜手术后，髁状骨具有形成新骨的能力，年龄越小，新骨形成能力越强。新骨形成最多的部位是髁突后斜面，最少的部位是髁突前斜面。
