查询词典 sphenoid

A subject was selected strictly from 30 healthy young people through nasal endoscopic examination, acoustic rhinometry measurement and CT scanning. Based on the CT image data of the subject, digital model of normal nasal cavity was reconstructed through Fluent 6.1.22 software. At the same time, according to the surgical requirements of FESS (remove the uncinate process and open the ethmoid sinus, maxillary sinus, and sphenoid sinus), post-FESS digital nasal cavity model was simulated. The viscous motion of nasal airflow before and after FESS was calculated by Navier-Stokes equations to compare the differences of airflow velocity, distribution, and pressure.

从30例健康青年人中，通过鼻内镜、鼻声反射测定仪及CT检查，严格筛选出一例研究对象，根据该入选对象的鼻腔CT影像资料，利用Fluent 6.1.22软件重建出正常鼻腔的数字模型，同时根据功能性鼻窦内镜手术的要求（切除钩突，开放筛窦、上颌窦和蝶窦）模拟出鼻内镜术后的鼻腔数字模型，再用Navier-Stokes方程对手术前后鼻腔气流的粘性运动进行数值计算，比较内镜手术前后鼻腔的气流速度、分布和压力的差异。
