摘　　要：目的探讨颏棘的解剖学测量值与螺旋CT影像学测量值的相关性.方法选取40具黄色人种成人尸头,男29具,女11具.先进行螺旋CT扫描,测量颏棘及其相关参数,然后对下颌骨及颏舌肌进行解剖,观察颏舌肌的起止点和走行,测量颏棘及其相关参数,所得到的数据应用SPSS 10.0统计软件计算平均值及标准差(±s),采用配对t检验和相关分析.结果颏舌肌几乎都起于上颏棘,颏舌骨肌起于下颏棘.颏棘及相关参数的解剖学测量和影像学测量值分别为上颏棘高度为(5.82±0.71)mm和(6.17±0.71)mm,宽度为(6.98±1.35)mm和(7.01±1.13)mm;颏下点至上颏棘下缘之间的距离为(11.08±2.05)mm和(10.41±1.55)mm;下中切牙根尖至上颏棘上缘的距离男性为(15.57±1.82)mm和(14.34±2.06)mm,女性为(9.36±2.79)mm和(8.78±2.53)mm;颏棘处下颌骨的厚度为(11.95±1.59)mm和(12.19±1.64)mm,颏下点至上颏棘上缘的距离为(16.91±2.30)mm和(15.73±2.12)mm.除上颏棘高度外,其他参数的解剖学测量与CT影像学测量显著相关(相关系数为0.59～0.92).结论颏棘的螺旋CT扫描能够真实地反映其解剖学形态,可为颏前移术中骨切口的准确定位和个体化设计提供有益的参考.Objective To study anatomic and computed tomographic measurements of Chinese mandibular genial tubercles and to evaluate the correlations between them. Methods The axial images were taken by spiral CT in 40 adult human skulls with 1 mm thick section from infraorbital margin to menton. Sagittal plane reconstruction was produced through mandibular central line. Then the height and width of superior genial tubercles, the distance between menton and inferior margin of genial tubercles, the distance between mandibular incisor apex and superior margin of superior genial tubercles, the thickness of mandible were measured respectively. Thereafter anatomic measurements were taken by the same methods as computed tomographic images. The measured value were showed as means ±standard deviation,then paired-t test and correlation analysis was made by SPSS 10.0. Results The genioglossus almost origins from superior genial tubercles, geniohyoideus from inferior genial tubercles. The height of superior genial tubercles which were measured by anatomy and spiral CT were (5.82±0.71)mm and (6.17±0.71)mm respectively. The width of superior genial tubercles were (6.98±1.35)mm and(7.01±1.13)mm. The distance between menton and inferior margin of superior genial tubercles were(11.08±2.05)mm and(10.41±1.55)mm. The distance between mandibular incisor apex and superior margin of superior genial tubercles for male were(15.57±1.82)mm and (14.34±2.06)mm, and for female were (9.36±2.79)mm和(8.78±2.53)mm. The thickness of mandibles at genial tubercles were(11.95±1.59)mm and(12.19±1.64)mm. The distance from menton to superior margin of superior genial tubercles were (16.91±2.30)mm and(15.73±2.12)mm. The correlations between anatomic measurements and spiral CT measurements of the above mentioned parameters were significant except for height of superior genial tubercles(r=0.59~0.92). Conclusion The anatomic and spiral CT measurements of genial tubercles appear to have significant correlations.Preoperative spiral CT measurements of gen
