To compare arthroscopy with radiography in patients with temporomandibular joint (TMJ) symptoms and generalized joint disease.
Twenty patients with generalized osteoarthritis (GOA) and TMJ symptoms and 21 patients with rheumatoid arthritis (RA) and TMJ symptoms were examined with arthroscopy and radiography (individualized oblique lateral transcranial projections and sagittal and frontal tomography).
In the GOA group there was a significant correlation between pronounced degenerative changes at arthroscopy and flattening of the eminence and reduced joint space superiorly and posteriorly on radiographs and between moderate to pronounced bone or disk remodelling and reduced joint space superiorly and posteriorly. In the RA group there was a significant correlation between moderate to pronounced degenerative changes at arthroscopy and radiographically extensive erosions in the condyle and between moderate to pronounced fibrosis and reduced translation.
Compared with conventional tomography, arthroscopy revealed TMJ pathology earlier and more frequently. It may therefore in individual cases be the first choice examination, particularly as treatment can be given simultaneously.
比较关节镜检查与放射成像在颞下颌关节（TMJ）症状和全身性关节疾病患者中的应用。
对20例患有全身性骨关节炎（GOA）和TMJ症状的患者以及21例患有类风湿性关节炎（RA）和TMJ症状的患者进行关节镜检查和放射成像（个体化斜侧经颅投影以及矢状面和额面断层扫描）。
在GOA组中，关节镜检查时明显的退行性改变与X线片上关节结节变平以及关节上方和后方间隙变窄之间存在显著相关性，中度至明显的骨或盘状重塑与关节上方和后方间隙变窄之间也存在显著相关性。在RA组中，关节镜检查时中度至明显的退行性改变与髁突X线片上广泛的侵蚀之间存在显著相关性，中度至明显的纤维化与平移减少之间也存在显著相关性。
与传统断层扫描相比，关节镜检查能更早且更频繁地发现TMJ病变。因此，在个别情况下，它可能是首选检查方法，特别是因为可以同时进行治疗。
