影响下颌骨轮廓解剖分区的三维重建研究

The study of the anatomical partition of the mandibular contour by three dimensional reconstruction

目的:通过三维重建测量影响下颌骨轮廓的解剖分区,探讨下颌骨轮廓的影响因素。方法:60例汉族成年女性头颅螺旋CT数据进行三维重建,测量影响下颌骨轮廓解剖分区的下颌骨及外板厚度。结果:下颌骨厚度:下颌骨升支后缘(6.96±0.63)mm,下颌角区(7.10±0.50)mm,下颌骨下缘(10.74±0.87)mm;下颌骨外板厚度:下颌骨升支后缘(3.12±0.34)mm,下颌骨下缘(3.97±0.34)mm,斜线区(5.33±0.42)mm。结论:通过对影响下颌骨轮廓的解剖分区的三维重建测量研究,将为下颌角整形手术术前设计、术后效果评价等方面提供理论基础和解剖依据。

Objective Through three dimensional reconstruction measurement anatomical partitions of mandibular contour, discussed the influence factors of mandibular contour. Methods 60 cases of Han nationality adult female head spiral CT data by the three dimensional reconstruction, measured the mandible and outer plate thickness of influenced mandible contour anatomical partition. Results The mandibular thickness： posterior border of mandibular ascending branch （6.96±0.63） mm; Mandibular Angle area （7.10±0.50） mm; inferior border of mandible （10.74±0.87）mm. Mandible outer plate thickness：posterior border of mandibular ascending branch （3.12±0.34）mm;inferior border of mandible （3.97± 0.34）mm;Slash area （5.33±0.42）mm. Conclusion Through study the influence anatomical partition of mandibular contour by three dimensional reconstruction measurement, to provide theoretical foundation and anatomical basis for preoperative design,the effect evaluation etc. of mandibular angle plastic surgery.
