OBJECTIVE
To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT).
STUDY DESIGN AND SETTING
Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods.
RESULTS
The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated.
CONCLUSION
Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement.
SIGNIFICANCE
This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy.
目的
采用解剖测量法和计算机断层扫描（CT）测量并比较中国人下颌颏结节。
研究设计与设置
对40个成人颅骨进行螺旋CT扫描；采用解剖学方法和CT方法测量颏上棘。
结果
解剖测量得出颏上棘的高度和宽度、下颌骨厚度以及颏点至颏上棘下缘和上缘的距离分别为5.82±0.71、6.98±1.35、11.95±1.59、11.08±2.05和16.91±2.30mm，螺旋CT测量结果分别为6.17±0.71、7.01±1.13、12.19±1.64、10.41±1.55和15.73±2.12mm。解剖测量与CT测量结果具有相关性。
结论
颏结节的螺旋CT有助于确定颏舌肌前移术中截骨的位置。
意义
本研究获取了中国人颏结节的参考数据，表明颏结节的CT测量反映了其解剖结构，有助于准确确定截骨位置
