The purpose of this research was to investigate the relationship between the TMJ articular disc and condyle by means of radiographical and anatomical approach, and to clarify the clinical details of TMJ arthrosis.In the financial year 1992 and 1993, arthrography of 30 cadavers' TMJ specimen was performed to observe morphologically three divided parts of TMJ,that is lateral, central and medial parts.The results were as follows : The type of biplanar disc was observed the most in lateral parts. The type of biconcave discs and enlargement of posterior band discs were observed the most in central and medial parts. The ratio of correspondence between the arthrotomographical and morphological findings were 83.3% in lateral part, 100% in central part and 93.3% in medial part. In several joints there was disagreement between the arthrotomographical and the morphological findings. In these cases, the disks were perforated or thinned.In the financial year 1994,19 clinically perforated cases and … More 84 non-perforated cases were identified by TMJ arthrotomography and analyzed be radiographical comparison.The results were as follows : Morphological analysis of the condyle and the articular disc revealed much abnormality in the perforated cases than non-perforated ones. In particular, many kinds of disc deformity were found in ever perforated case. Morphological measurement of mandibular fossa revealed significantly smaller values in the horizontal diameter, vertical diameter and front length in the perforated cases than the non-perforated ones (P<0.05) . Using another word, perforated cases had the tendency showing shallow and narrow mandibular fossa.These results suggested that the perforation of the TMJ articular disc was the condition of the advanced TMJ arthrosis. The preceding results made some contribution for clarification of the clinical details of TMJ arthrosis, but the mechanism of progress of TMJ arthrosis is still be elucidated.Therefore, further investigation must be continued.

本研究的目的是通过放射学和解剖学方法研究TMJ关节盘与髁突的关系，明确TMJ关节病的临床细节。在1992和1993财政年度，对30具身体TMJ标本进行了关节造影，对TMJ的外侧、中央和内侧三个部分进行了形态观察。结果表明：TMJ的类型以外侧最多。中央部和内侧部以双凹型和后带型最多见。关节体层摄影与形态符合率外侧83.3%，中部100%，内侧93.3%。在几个关节中，关节断层摄影术和形态学检查结果不一致。在这些病例中，椎间盘被穿孔或变薄。在1994财政年度，19例临床穿孔病例和…对84例TMJ未穿孔病例进行了关节体层摄影检查，并与X线片进行了对比分析，结果表明：穿孔病例的髁突和关节盘形态分析较未穿孔病例明显异常。尤其是曾经穿孔的病例，可见多种类型的椎间盘畸形。下颌窝形态测量显示，穿孔病例下颌窝的横径、垂径和前长均明显小于未穿孔病例(P&lt；0.05)。也就是说，穿孔病例有下颌窝变浅变窄的趋势，提示TMJ关节盘穿孔是晚期TMJ关节病发生的条件。前人的研究结果为阐明TMJ关节病的临床细节做出了一定的贡献，但TMJ关节病的发病机制尚不清楚，有待于进一步研究。较少
