摘　　要：目的为颞下间隙疾病的影像诊断提供解剖学资料。方法选用成尸头颈部40例制成连续矢、冠状断面,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。结果颞下间隙的矢、冠状断面呈不规则形,经茎突等层面的面积分别为:(450.6±4.62)mm2(左)、(452.2±4.71)mm2(右),(625.3±6.05)mm2(左)、(627.7±6.13)mm2(右),(153.8±3.41)mm2(左)、(155.3±3.52)mm2(右),(350.9±4.58)mm2(左)、(352.8±4.49)mm2(右),两侧颞下间隙及邻近结构呈对称性,长径、横径和面积的差异均无统计学意义(P>0.05)。冠状面上自翼内肌上缘至卵圆孔内侧壁的连线可区分颞下间隙与咽旁间隙。翼外肌、茎突和翼突是CT等影像诊断的重要解剖学标志。结论颞下间隙的矢、冠状断层解剖对疾病的影像诊断具有重要意义。Objective To provide anatomical data for imaging diagnosis of the infratemporal space diseases. Methods Forty head and neck of adult cadaver were selected and cut into sagittal and coronal sequence section respectively. Infratemporal space and its adjacent structures were observed and measured in the diameter and area with vernier caliper and planimeter. Results Sagittal and coronal section of the infratemporal space was irregular. At the level of styloid process, and so on, it was （450.6±4.62） mm^2 （left） and （452.2 ±4.71） mm^2 （right）, （625.3± 6.05） mm^2 （left） and （627.7±6.13） mm^2 （right）, （153.8±3.41） mm^2 （left） and （155.3±3.52） mm^2 （right）, （350.9± 4.58） mm^2 （left） and （352.8±4.49） mm^2 （right）. Infratemporal space and its adjacent structures were symmetrical on both sides. There were no significant differences in the length, width and area （P〉0.05）. Infratemporal space and parapharyngeal space were divided by the line from superior margin of medial pterygoid muscle to medial wall of foramen ovale on coronal section. Lateral pterygoid muscle, styloid process and pterygoid process were important anatomical marks for imaging diagnosis. Conclusion Sagittal and coronal sectional anatomy of the infratemporal space has important clinical significance for imaging diagnosis of diseases.
