OBJECTIVE
To determine the accuracy of cone beam computed tomography (CT) to predict the location of the genial tubercle.
STUDY DESIGN AND SETTING
Cadaver study for anatomic analysis of 17 adult human cadaver heads. Each skull/cadaver head underwent radiographic imaging with cone beam CT and cadaver dissection. Measurements, including mandibular height (MH), genial tubercle width (GTW), genial tubercle height (GTH), distance from inferior border of mandible to genial tubercle (IBM/GT), and mandibular thickness (MT) were recorded.
RESULTS
Statistical analysis with paired t test showed no significant difference between cadaver dissections versus cone beam measurements. Ninety-five percent confidence intervals (CI) were as follows: GTW (-0.2 to 1.0), GTH (-0.1 to 0.9), distance IBM/GT (-0.8 to 5.0), MH (-1.3 to -2.6), and MT (-0.1 to 0.3).
CONCLUSION
These results show the accuracy of the 3D cone beam CT in the anatomic location of the genial tubercle.
SIGNIFICANCE
This radiographic technique may prove useful in pre-operative planning for the mandibular osteotomy in genioglossus advancement procedures.
目的
确定锥形束计算机断层扫描（CT）预测颏结节位置的准确性。
研究设计与设置
对17个成人尸体头部进行解剖分析的尸体研究。每个颅骨/尸体头部均接受锥形束CT影像学检查及尸体解剖。记录包括下颌高度（MH）、颏结节宽度（GTW）、颏结节高度（GTH）、下颌下缘至颏结节的距离（IBM/GT）以及下颌厚度（MT）等测量数据。
结果
配对t检验的统计分析表明，尸体解剖测量值与锥形束测量值之间无显著差异。95%置信区间（CI）如下：GTW（-0.2至1.0），GTH（-0.1至0.9），距离IBM/GT（-0.8至5.0），MH（-1.3至-2.6），以及MT（-0.1至0.3）。
结论
这些结果显示了三维锥形束CT在颏结节解剖定位中的准确性。
意义
这种影像学技术可能在颏舌肌前移手术中下颌骨截骨术的术前规划中证明有用。
