目前对TMJ病变诊断主要依赖影像学检查,尽管这些检查能显示TMJ功能解剖定性方面,但不能提供TMJ解剖生理变化的定量参考值及病理变化的最低限参考值。因而有必要进行尸检获取有关数据为临床提供参考。为此,本文通过大体形态测量及组织学形态测量的方法观察关节盘及髁突软骨厚度变化及与TMJ病变的可能联系。 材料和方法 取53具福尔马林固定的尸体,其中男25例,女28例,年龄65～85岁。矢状切开头颅,横切TMJ侧副韧带使关节盘与髁突分离,肉眼检查髁突及关节盘表面,再沿关节盘表面中间致密部标定5个点,在各点测量关节盘厚度。然后将关节盘复位,脱矿后,沿额面且通过关节盘、髁突的中间致密部切开
At present, the diagnosis of TMJ lesions mainly depends on the imaging examination. Although these tests can show anatomic qualitative aspects of TMJ function, they can not provide the quantitative reference value of TMJ anatomical and physiological changes and the minimum reference value of pathological changes. Therefore it is necessary to conduct autopsy to obtain relevant data for clinical reference. To this end, this article through gross morphology measurement and histological measurement methods to observe the changes in articular disc and condylar cartilage thickness and the possible relationship with TMJ lesions. Materials and Methods 53 formalin-fixed corpses, including 25 males and 28 females, were aged 65-85 years old. The saphenous incision of the skull was performed transversely to the TMJ collateral ligament to separate the articular disc from the condyles. The condyles and articular disc surfaces were examined visually. Five points along the dense surface of the articular disc surface were then calibrated and the thickness of the articular disc measured at each point. The disk is then reset, demineralized, cut along the frontal plane and through the disk, and the condyle's central dense section
