摘　　要：目的 通过三维重建测量下颌角各相关角度和下颌角间距,探讨各数据间的相关性.方法 对60例成年女性头颅螺旋CT数据进行三维重建,测量下颌角各相关角度以及下颌角间距.测量结果输入SPSS13.0软件,分析下颌角各相关角度间以及各相关角度与下颌角间距之间的相关性.结果 下颌角相关角度：下颌角（124.28±4.12）°,下颌仰角（25.52±2.22）°,下颌角外翻角（9.35±7.85）°,下颌夹角（77.32±2.34）°,下颌切线角（105.53±1.79）°.下颌角各相关角度间及其与下颌角间距之间存在相关性.结论 通过下颌角各相关角度的测量,及其与下颌角间距之间的相关性分析,可为下颌角整形手术术前设计、术后效果评价等提供理论基础和依据.Objective To explore the correlation of data obtained through three dimensional reconstruction and measurement of mandibular angle related angles and bigonial breadth.Methods Sixty cases of adult female head spiral CT data were involved in this study.By the three dimensional reconstruction,mandibular angle related angles and bigonial breadth were measured.Through SPSS13.0 software their correlation was analyzed,including among mandibular angle related angles and these with bigonial breadth.Results The related data of the mandibular angle were measured on the image of three dimensional reconstruction; the mandibular angle was （124.28±4.12）°,the mandibular elevated angle was （25.52±2.22）°,the valgus angle of mandibular angle was （9.35±7.85）°,the mandiblular included angle was （77.32 ± 2.34）°,and the tangent angle of mandible was （105.53 ± 1.79）°.The correlation analysis of the related angles of mandibular angle and bigonial breadth showed that there was a significant correlation between the angles.Conclusions Three dimensional reconstruction and measurement of mandibular angle related angles and their correlation analysis can provide theoretical foundation and basis for the preoperative design and effect evaluation of mandibular angle plastic surgery.
