Comparisons among several temporomandibular joint autopsy studies indicate that the frequency of arthrosis and disk displacement is higher in elderly persons. The aim of this study was to investigate type, frequency, and location of morphologic changes in temporomandibular joint autopsy specimens divided into two groups according to age and to determine the differences between the two groups. For this purpose 68 temporomandibular joints were removed from 37 persons at autopsy. Group I (young) consisted of 36 specimens belonging to 19 persons with a mean age of 30 years (range, 16 to 39 years). Group II (elderly) consisted of 32 specimens from persons with a mean age of 68 years (range, 55 to 78 years). Significant differences between the two groups were observed with respect to several of the morphologic changes that were evaluated. The results of this study suggest that the frequency of morphologic changes such as deviation in form, arthrosis, perforations, disk displacement, disk deformation, and adhesions is higher in the temporomandibular joints of elderly persons.
多项颞下颌关节尸检研究表明，老年人中关节病和盘移位的发生率更高。本研究的目的是调查根据年龄分为两组的颞下颌关节尸检标本中形态学改变的类型、发生率和位置，并确定两组之间的差异。为此，在尸检时从37人身上取下68个颞下颌关节。第一组（年轻组）由属于19人的36个标本组成，平均年龄为30岁（范围16至39岁）。第二组（老年组）由平均年龄为68岁（范围55至78岁）的人的32个标本组成。在评估的几种形态学改变方面，两组之间观察到显著差异。本研究结果表明，老年人颞下颌关节中形态学改变如形态偏差、关节病、穿孔、盘移位、盘变形和粘连的发生率更高。
