Abstract:
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.
