基于螺旋CT影像的计算机辅助重建及测量上颌窦的实验研究

目的：建立一种基于螺旋CT影像的计算机辅助重建及测量上颌窦的方法,为上颌窦辅助诊断、手术治疗提供参考。方法：利用64排螺旋CT对60例正常成人（男30例,女30例）颌骨进行薄层容积扫描,将DICOM数据输入计算机辅助软件Simplant,重建上颌窦,测量相关数据并进行统计学分析。结果：上颌窦前后径均值为（35.12±3.47）mm,上下径均值为（39.58±2.96）mm,左右径均值为（32.14±2.50）mm,上颌窦容积均值为（15187.16±596.12）mm3。左右侧上颌窦径线值和容积无显著差异。男女性上颌窦径线值和容积无显著性差异。结论：利用该方法获得的上颌窦重建影像和测量数据可以为上颌窦影像诊断和手术治疗提供参考。

Experimental Study of Maxillary Sinus Reconstruction and Measurement using Computer Assisted Technology Based Spiral CT Images

Objective： To investment reconstruction and measurement maxillary sinus using computer assisted technology based Spiral CT images for clinical diagnosis and operation of maxillary sinus.Methods： 60 health adults（male 30,female 30） were chose to receive spiral CT scan and DICOM data were processed by Simplant software for maxillary sinus reconstruction and measurement.Results： The anteroposterior,up-down and left-right diameter of maxillary sinus 35.12±3.47mm,39.58±2.96mm and 32.14±2.50mm respectively.The mean volume of maxillary sinus was 15187.16±596.12 mm3.There was no statistical significant difference between genders and sides in terms of volume and diamerer.Conclusion： The computer assisted technology can provide valuable data for clinical treatment.
