摘　　要：目的分析成人正常翼钩的CT表现，提高对翼钩影像学改变的认识。方法选取翼钩结构正常的成年人108名，男53名（106侧）、女55名（110侧），对其行64排螺旋CT扫描的翼钩进行MIP和VR重建；观察其形态，测量长度、直径、垂直高度、水平宽度、冠状面外展角度及矢状面后展的角度，统计学方面，侧别比较使用配对样本t检验，性别比较使用两独立样本t检验，不同年龄组之间数据的比较使用多个样本均数间的F检验。结果正常翼钩基底稍宽，体部呈柱状，末端圆钝或膨大；冠状面远端朝向外方214侧，内方2侧；矢状面远端朝向后方190侧，朝向前方26侧；成年男性翼钩长度为（8．18±0．94）mm、垂直高度为（7．23±0．92）mm、水平宽度为（4．27±0．81）mm，成年女性的长度为（7．31±1．01）mm、垂直高度为（6．26±0．90）mm、水平宽度为（3．97±0．82）mm，差异均有统计学意义（t值分别为6．56、7．86、2．72，P〈0．05）。60岁以上成人翼钩垂直高度为（7．13±1．35）mm，大于18～39岁组的（6．55±0．86）mm，差异有统计学意义（F=4．95，P〈0．05）。结论64排螺旋CT能详细显示翼钩的形态、长度、角度等，可对临床翼钩相关病变的认识提供帮助。Objective To recognize the normal CT appearances of adult pterygoid hamulus and increase the ability to recognize pterygoid hamulus abnormalities. Methods The pterygoid hamulus of 108 normal adults （male： 53 cases, female, 55 cases） were studied with MIP and VR reconstructive images by 64-slice spiral CT in order to observe its normal shape, to measure its length, diameter, vertical height, horizontal width, abduct angle in coronal position and post-abducent angle in anteroposterior position. The differences between genders, two sides and age groups were compared, respectively. Results The normal pterygoid hamulus had a wide basal body and a pillar caudomedial part with round or intumescentia extreme. In coronal position, the distal end towards outer direction in 214 sides and 2 sides in inner direction. In anteroposterior position, the distal end towards posterior direction in 190 sides and anterior direction in 26 sides. The pterygoid hamulus length, vertical height, and horizontal width of adult males were （8.18 ± 0. 94） mm, （7. 23 ±0. 92） mm, （4. 27 ±0. 81） mm, respectively. They were larger than the adult females （7.31 ± 1.01） mm, （6.26 ±0.90） mm, （3.97 ±0.82） mm, and the difference was statistically significant （t values were 6.56,7.86,2. 72 respectively, P 〈 0. 05 ）. The pterygoid hamulus vertical height of age group over 60 years old （7.13 ± 1.35） mm exceeded the age groups of 18-39 （6. 55 ±0. 86） mm. The difference was statistically significant （ F = 4. 95, P 〈 0. 05 ）. Conclusions 64-slice spiral CT could display the shape, length and angle of pterygoid hamulus in full. It could help to recognize correlated pterygoid hamulus diseases.
