Abstract：
OBJECTIVE: To investigate how the results of nasal computational fluid dynamics (CFD) simulations change due to inferior turbinate surgery and how the results correlate with patient specific subjective assessment and volumetric results in the nasal cavities.
METHODS: The steady inspiratory airflow of 25 patients was studied pre- and postoperatively with heat transfer from the mucous membrane by performing CFD calculations to patient-specific nasal cone beam computed tomography images. These results were then compared to the severity of the patients\' nasal obstruction Visual Analogue Scale (VAS) and Glasgow Health Status Inventory assessments, and acoustic rhinometry measurements.
RESULTS: Total wall shear forces decreased statistically significantly (p < 0.01) in the operated parts of the inferior turbinates. Patients\' subjective nasal obstruction VAS assessment changes between the pre- and postoperative conditions correlated statistically significantly (p = 0.04) with the wall shear force results.
CONCLUSIONS: Inferior turbinate surgery lead to decreased total wall shear force values postoperatively. Changes in subjective nasal obstruction VAS results against total wall shear force changes between the pre- and postoperative conditions were statistically significant. CFD data have a potential to be used for the evaluation of nasal airflow.

摘要：
目的：研究鼻计算流体动力学（CFD）模拟结果因下鼻甲手术而发生的变化，以及该结果如何与患者的主观评估和鼻腔体积结果相关。
方法：通过对患者特定的鼻锥形束计算机断层扫描图像进行CFD计算，研究了25例患者术前和术后从粘膜传热的稳定吸气气流。然后将这些结果与患者鼻塞视觉模拟评分(VAS)和格拉斯哥健康状况评估的严重程度进行比较。和声学鼻测量。
结果：下鼻甲手术部位的总壁剪切力在统计学上显着降低（p<0.01）。患者的主观鼻塞VAS评估在术前和术后状况之间的变化与壁剪切力结果具有统计学上的显着相关性（p=0.04）。
结论：下鼻甲手术导致术后总壁剪切力值降低。主观鼻塞VAS结果相对于术前和术后状况之间总壁剪切力变化的变化具有统计学意义。CFD数据有可能用于评估鼻腔气流。
