目的 :探讨颞下颌关节骨软骨瘤并发滑膜软骨瘤病的诊断与治疗。方法 :回顾2001—2013年颞下颌关节骨软骨瘤和滑膜软骨瘤病患者的临床资料,最终确诊为原发性骨软骨瘤并发滑膜软骨瘤病患者共3例。对病史、临床表现、影像学检查和病理特征,以及之后3个月~5年的随访结果进行总结。结果:CT和MRI可提供精确的术前诊断,骨软骨瘤中发现游离软骨化或钙化小体,提示骨软骨瘤并发滑膜软骨瘤病可能。结论:治疗过程中需注意游离小体的存在,常提示骨软骨瘤并发滑膜软骨瘤病的可能,以免漏诊或误诊。
Objective: To investigate the diagnosis and treatment of temporomandibular joint osteochondroma combined with synovial chondromatosis. Methods: The clinical data of patients with temporomandibular joint osteochondroma and synovial chondromatosis from 2001 to 2013 were reviewed. A total of 3 patients with primary osteochondroma complicated with synovial chondromatosis were finally diagnosed. The clinical history, clinical manifestations, imaging and pathological features, and follow-up results from 3 months to 5 years were summarized. Results: CT and MRI could provide accurate preoperative diagnosis. Free or calcified bodies were found in osteochondroma, suggesting that osteochondroma might be associated with synovial chondromatosis. Conclusion: It is necessary to pay attention to the existence of free body in the course of treatment, which often indicates the possibility of osteochondroma complicated with synovial chondromatosis so as to avoid misdiagnosis or misdiagnosis.
