Chronic rhinosinusitis is commonly treated by functional endoscopic sinus surgery involving excision of the uncinate process and opening of the osteomeatal complex.
Computational fluid dynamics were used to compare nasal airflow after two different surgical interventions which involved opening the paranasal sinuses, excising the ethmoid sinus, and excising or preserving the uncinate process, in a cadaveric head model. Cross-sectional computed tomography images were obtained before and after the interventions. Imaging data were used to prepare computer simulations, which were used to assess the airflow characteristics of the nasal cavities and paranasal sinuses during inspiration and expiration, before and after intervention.
Significantly larger nasal cavity airflow velocity changes were apparent following the uncinate process excising procedure. Nasal cavity airflow distribution remained relatively unchanged following the uncinate process preserving procedure. There was a significantly greater increase in airflow volume following the uncinate process excising procedure, compared with the uncinate process preserving procedure.
Preservation of the uncinate process may significantly reduce the alteration of nasal cavity airflow dynamics occurring after functional endoscopic sinus surgery for chronic rhinosinusitis.
慢性鼻窦炎通常通过功能性鼻内镜鼻窦手术治疗，该手术包括切除钩突和开放鼻窦开口复合体。
在尸体头部模型中，使用计算流体动力学比较两种不同手术干预后的鼻腔气流情况，这两种手术干预包括开放鼻窦、切除筛窦以及切除或保留钩突。在干预前后获取横断面计算机断层扫描图像。利用成像数据进行计算机模拟，以评估干预前后吸气和呼气时鼻腔和鼻窦的气流特征。
切除钩突手术后鼻腔气流速度变化明显更大。保留钩突手术后鼻腔气流分布相对不变。与保留钩突手术相比，切除钩突手术后气流体积增加显著更大。
保留钩突可能显著减少慢性鼻窦炎功能性鼻内镜鼻窦手术后鼻腔气流动力学的改变。
