【摘要】 目的三维测量与下颌角肥大诊断相关的指标,为下颌角截骨术手术适应证的选择提供相关解剖学依据。方法选择2003年至2006年,50例临床下颌角肥大就诊患者(女性46例,男性4例,平均年龄29岁),均行螺旋CT检查和颅骨三维重建,测量下颌角角度、下颌角外翻角度、下颌升支高度、下颌角间宽及下颌夹角,并对各指标进行t检验和相关检验统计分析。结果所测病例下颌角角度、下颌角外翻角度及下颌升支高度的左右侧无明显差异(P>0.05);下颌角外翻角度为左侧36.46±12.41°,右侧37.69±12.41°;下颌角外翻角度与下颌角间宽呈显著相关(r=0.453,P<0.05);下颌角外翻角度与下颌夹角呈显著相关(r=0.717,P<0.05)。结论下颌角外翻角度对下颌角肥大患者手术适应证的选择有较大临床指导意义。更多还原

【Abstract】 Objective To provide anatomical bases for prominent mandibular angle plasty.Methods 50 adult mandibles of patients who have prominent mandible angle were under computer 3D measuring based on the CT data. Measure the angle of mandibular angle,height of mandible ramus, width between bilateral mandibular angle, mandible included angle and valgus angle of mandibular angle,meanwhile,analyze the correlativity between them. Results There was no significant differences between bilateral angle of mandibular angle,height of mandible ramus,width between bilateral mandibular angle and valgus angle of mandible angle(P> 0.05).There was obviously positive correlation between valgus angle of mandibular angle and width between bilateral mandibular angle, mandible included angle (P< 0.05).Conclusion This study provide reliable 3D measure anatomical databases for prominent mandibular angle plasty.更多还原
