以鼻窦引流通道为关注点的断面解剖模型设计

Design of cross-sectional anatomical model focused on drainage pathways of paranasal sinuses

目的:以展示各鼻窦气房引流为目的,设计和制作用于鼻腔鼻窦解剖学习及研究的鼻窦断面解剖模型。方法:使用Mimics软件将鼻窦CT元数据重建成三维数字模型。经鼻丘气房中部、筛泡气房中部、后组筛窦中部、蝶窦中部做4个冠状切面,将数字模型分为5个厚层断面模型,再利用3D打印机制作实体断面解剖模型以供学习和研究。结果:成功制作了鼻窦数字三维模型及3D打印断面解剖模型,观察了模型对各气房的引流的展示效果。结论:该方法制作的解剖模型可以真实、形象和直观地展示各个气房引流口的精确位置,有助于年轻医生快速理解和掌握鼻腔鼻窦内镜手术相关的关键解剖结构及其位置关系,有助于学习以鼻窦引流为导向的手术理念。

Objective：To design and produce cross-sectional anatomical models of paranasal sinuses for the purpose of demonstrating drainage pathways of each nasal sinus for the young doctors.Method：We reconstructed the three-dimensional model of sinuses area based on CT scan data,and divided it into 5 thick cross-sectional anatomy models by 4 coronal plane,which cross middle points of agger nasi cell,ethmoid bulla,posterior ethmoid sinuses and sphenoid sinus respectively.Then a 3D printerwas used to make anatomical cross-sectional anatomical models.Result：Successfully produced a digital 3D printing cross-sectional models of paranasal sinuses.Sinus drainage pathways were observed on the models.Conclusion：The cross-sectional anatomical models made by us can exactly and intuitively demonstrate the ostia of each sinus cell and they can help the young doctors to understand and master the key anatomies and relationships which are important to the endoscopic sinus surgery.
