摘要：

目的　探讨颞下颌关节冠状面形态结构的关系。方法　将福尔马林液浸泡1年以上的,能将下颌固定在牙尖交错位的15具尸头的28侧TMJ,斜冠状位磁共振质子加权扫描,以下颌升支中线为基准,作相应测量。结果　①横径由大到小排序为:关节窝内外径、髁突内外径、关节窝内径、髁突内径、髁突外径、关节窝外径。②髁突外径与关节窝外径间,髁突内径与关节窝内径间,髁突内外径和关节窝的内外径间均存在正相关关系。③变异系数关节窝外径大于髁突外径、内径大于其他横径。④关节间隙面积与关节盘断面面积正相关。结论　颞下颌关节各结构的冠状形态及大小具有高度协调性,髁突相对于关节窝的内外位置关系具有较大的变异范围。

Abstract:

Objective　To investigate the MR imagine features of TMJ coronal structures.Methods　28 TMJs from 15 cadav- ers dipped in formalin over1 yearwere included. Theirmandibleswere fixed at intercuspal positionwhenTMJs oblique coronalMR scan was taken. Baseline was draw on the oblique coronal imagining along the ramus of mandible through its center. The corre- sponding dimensions and areas were measured with electronic ruler.Results　The dimensions were in accordance from large to small as: lateral-medial dimension of fossa, lateral-medial dimension of condyle, medial dimension of fossa, medial dimension of condyle, lateral dimension of condyle and lateral dimension of fossa. Three significant co-relative relationshipwere found: the lat- eral dimension of condyle with lateral dimension of fossa, the medial dimension of condyle withmedial dimension of fossa, and the lateral-medial dimension of condyle with lateral-medial dimension of fossa. CVof lateral dimension of fossa was higher than that of lateral and medial dimension of condyle, and then all the three were higher than other dimensions. The size of the area of joint space shown on oblique coronal imaginings was positively related to that of the area of coronal disc imaginings.Conclusion　Sig- nificant co-ordinate relationship of condyle and fossa ofTMJ coronallywas existed, and the condyle position to fossa lateral-medial- ly varied in great.
