上呼吸道气流数值模拟在鼻外科手术中的应用
Patient specific numerical simulation of flow in the human upper airways for assessing the effect of nasal surgery
摘要：
这项研究正在探讨使用计算流体动力学（CFD）作为预测缓解阻塞性睡眠呼吸暂停综合征（OSAS）手术结果的工具的潜力。根据OSAS患者的术前和术后计算机断层成像（CT），生成患者上气道的术前和术后几何形状。患者上气道中的层流的CFD模拟显示，在鼻部手术之后，质量流在两个鼻腔之间更均匀地分布，并且鼻腔上的压降增加。压力变化与CFD结果进行比较的临床测量结果相反，这很可能与建模的早期步骤- CT采集和几何检索有关。
英文摘要：
The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative computed tomography (CT) of an OSAS patient, the pre- and post-operative geometries of the patient's upper airways were generated. CFD simulations of laminar flow in the patient's upper airway show that after nasal surgery the mass flow is more evenly distributed between the two nasal cavities and the pressure drop over the nasal cavity has increased. The pressure change is contrary to clinical measurements that the CFD results have been compared with, and this is most likely related to the earlier steps of modelling - CT acquisition and geometry retrieval.
