| 摘 要： | 目的观察颞下间隙及邻近结构的解剖学关系,为颞下间隙疾病的CT诊断提供断层影像解剖学资料。方法选用40例扫描对称的正常CT片,观察颞下间隙及邻近结构的解剖学关系,利用游标卡尺及求积仪分别测量其径线和面积。结果颞下间隙的断面呈不规则形,两侧颞下间隙及邻近结构对称分布,长径、横径和面积均无显著性差异(P>0.05)。横断面上自翼突后缘至髁突内侧缘和自茎突至翼突内侧板后缘或翼突外侧板前缘的连线可区分颞下间隙与咽旁间隙。结论翼外肌、茎突、翼突及其内、外侧板是CT等影像诊断的重要解剖学标志。颞下间隙的影像解剖对颞下间隙疾病的CT诊断等具有重要临床意义。

| Abstract: | Objective To provide sectional imaging anatomical data for CT diagnosis of the infratemporal space diseases,infratemporal space and its adjacent structures were observed.Methods Infratemporal space and its adjacent of their anatomical relationship structures were observed in the selected 40 normal and symmetrical CT scans to measure in their diameters and their areas with vernier caliper and planimeter.Results The shapes of the infratemporal space were irregular.The infratemporal space and its adjacent structures were symmetrical on both sides.There were no significant differences in their length,width and area(P>0.05).The infratemporal space and parapharyngeal space were divided by the line from the posterior margin of pterygoid precess to medial margin of condylar process and styloid process to postior margin of medial or anterior margin lateral pterygoid plate on transverse.Conclusion The lateral pterygoid muscle,styloid process,pterygoid process and its medial,lateral pterygoid plate were important anatomical marks for CT imaging diagnosis.Imaging anatomy of the infratemporal space has important clinical significance for CT diagnosis of the infratemporal space diseases. |
