摘要:

目的 利用鼻窦平扫CT通过三维重建软件Mimics17.0计算我国成年人上颌窦及蝶窦容积,并分析其性别差异。 方法 选取北京大学第三医院鼻窦平扫CT图像98例,利用Mimics 17.0三维重建软件重建上颌窦及蝶窦的数字化模型,通过三维立体数字化模型获取鼻窦容积。 结果 男性右侧上颌窦平均容积(16.69±6.90)ml,男性左侧上颌窦平均容积为(16.88±7.12)ml。男性右侧蝶窦平均容积为(4.62±2.99)ml,男性左侧蝶窦平均容积为(5.58±3.72)ml。女性右侧上颌窦平均容积为(11.39±5.63)ml,女性左侧上颌窦平均容积为(11.37±5.38)ml。女性右侧蝶窦平均容积为(4.12±2.53)ml,女性左侧蝶窦平均容积为(3.32±2.30)ml。其中左侧蝶窦、双侧上颌窦体积具有性别差异。 结论 三维重建可以快速获得鼻窦的三维模型,准确计算鼻窦容积,并且可以通过鼻窦体积间接反映性别。为进一步了解鼻窦立体解剖提供参考。

Abstract:

Objective To calculate the volume of maxillary sinus and sphenoid sinus of adults in China by CT, and to analyze the differences of gender in the adult maxillary sinus and sphenoid sinus.  Methods Ninety-three CT images of sinus were randomly selected from Peking University Third Hospital. The digital model of maxillary sinus and sphenoid sinus was reconstructed by Mimics17.0 3D reconstruction software. And the sinus volume was obtained by the three-dimensional digital model.  Results The average volume of the right maxillary sinus in the male was (16.69±6.90) ml, and the average volume of the maxillary sinus in the left side of the male was (16.88±7.12) ml. The average volume of the right sphenoid sinus of male was (4.62±2.99) ml, and the average volume of the left sphenoid sinus of male was (5.58±3.72) ml. The average volume of the right maxillary sinus in female was (11.39±5.63) ml, and the average volume of the left maxillary sinus in female was (11.37±5.38) ml. The average volume of the right sphenoid sinus of female was (4.12±2.53) ml, and the average volume of the left sphenoid sinus of female was (3.32±2.30) ml. The left sphenoid sinus and bilateral maxillary sinus volume had gender differences.  Conclusion Three-dimensional reconstruction can quickly obtain a three-dimensional model of the sinus, accurately calculate the sinus volume, and indirectly reflect gender through the sinus volume. It provides a certain reference for further understanding of sinus anatomy.
