OBJECTIVE
The aim of this study was to investigate the prevalence of TMJ chondrocalcinosis on head CT scans in patients with chondrocalcinosis of the knee or wrist.
METHODS AND MATERIALS
227 patients with radiological evidence of calcifications on knee or wrist radiographs had a head CT scan obtained for unrelated purposes. CT scans were retrospectively reviewed for the presence of temporomandibular crystal deposition. Prevalence, bilaterality, age and gender distribution were determined.
RESULTS
41 of 227 (18%) of patients had TMJ chondrocalcinosis. TMJ chondrocalcinosis was more common in females (17%) than males (1%). It was more commonly unilateral (68%) than bilateral (32%).
CONCLUSION
In patients with peripheral calcific disease, the TMJ is more commonly involved than previously reported and this is more common in females compared to males.
目的
本研究旨在探讨膝关节或腕关节软骨钙质沉着症患者头部 CT 扫描中 TMJ 软骨钙质沉着症的患病率。
方法与材料
227 例膝关节或腕关节 X 线片有钙化证据的患者因其他目的进行头部 CT 扫描。回顾性分析 CT 扫描是否存在颞下颌关节晶体沉积。确定患病率、双侧性、年龄和性别分布。
结果
227 例患者中有 41 例（18%）存在 TMJ 软骨钙质沉着症。女性（17%）比男性（1%）更常见 TMJ 软骨钙质沉着症。更常见单侧（68%）而非双侧（32%）。
结论
在患有周围钙化疾病的患者中，TMJ 的受累情况比先前报道的更为常见，且女性比男性更为常见。
