摘　　要：目的:根据发表于2016年的国际额窦解剖分型(IFAC),探索基于CT数据的3D重建技术在研究额窦引流通道中的应用价值。方法:利用Mimics 19.0软件对100例患者鼻窦CT的DICOM格式数据进行三维重建,通过3D模型来研究额窦解剖分型,观察额隐窝区气房的位置关系及对额窦引流通道的影响。结果:成功重建出额窦、额隐窝区各气房及额窦引流通道的3D模型。其中,鼻丘气房的出现率为95.5%(191/200)、鼻丘上气房的出现率为31.5%(63/200)、鼻丘上额气房的出现率为24.5%(49/200)、筛泡上气房的出现率为54.0%(108/200)、筛泡上额气房的出现率为14.5%(29/200)、眶上筛房的出现率为20.5%(41/200)、额窦中隔气房的出现率为4.0%(8/200),并直观地展示了额隐窝气房之间的位置关系及对额窦引流通道的影响。结论:基于CT数据的3D重建技术不仅可以帮助我们直观地理解额窦解剖分型、额隐窝气房的相对位置及对额窦引流通道的影响,更为鼻内镜额窦手术的术前规划、术中指导提供了一种新的方法,具有临床推广价值。Objective：The aim of this study is to explore the value of 3D reconstruction technology based on computer tomography data in understanding the frontal sinus drainage pathway.Method：Three-dimensional reconstruction of DICOM data from 100 cases of sinus CT was performed by using Mimics 19.0 software.The 3D models were used to study types,the relative locations of frontal sinus and recess cells as well as the influence of the frontal sinus drainage pathway.Result：The 3D model of frontal sinus,frontal recess cells and frontal sinus drainage pathway were reconstructed successfully.Among them,the incidence of nasal cavity was 95.5%（191/200）,nasal cavity was 31.5%（63/200）,nasal cavity on the frontal air room was 24.5%（49/200）supra bulla cells were 54%（108/200）,supra bulla frontal cells were 14.5%（29/200）,supraorbital ethmoid cells were 20.5%（41/200）,and the rate of frontal septal cells were 4%（8/200）.It visually demonstrated the relationship between the frontal recess and the frontal sinus drainage channel.Conclusion：The 3D reconstruction technology based on computer tomography data not only helps us to understand the anatomy of the frontal sinus,the relative position of the frontal crypt and the effect on the frontal sinus drainage channel,but also provides a new method for preoperative planning and intraoperative guidance to endoscopic frontal sinus surgery.
