This article summarizes the results of computer simulation of the air flows in the nasal cavity and the maxillary sinus by the computational fluid dynamics (CFD) method. The objective of the study was to apply the method of computational aerodynamics to simulate the air flows in the nasal cavity and the maxillary sinus under the normal conditions and after the surgical interventions on the middle nasal meatus. The normal air space of the nasal cavity and paranasal sinuses was simulated and the computer modeling of the main options for the surgical approach to the maxillary sinus through the middle nasal meatus was performed including balloon sinuplasty, functional endoscopic sinus surgery, and uncinate process mobilization. The study has demonstrated the increase of the air flow velocity in the maxillary sinus after computer-assisted balloon sinuplasty. The computer simulation of functional endoscopic sinus surgery including the removal of the uncinated process revealed the mass exchange between the maxillary sinus and the nasal cavity.
本文总结了采用计算流体动力学（CFD）方法对鼻腔和上颌窦内气流进行计算机模拟的结果。该研究的目的是应用计算空气动力学方法，模拟正常情况下以及中鼻道手术干预后鼻腔和上颌窦内的气流。模拟了鼻腔和鼻窦的正常气腔，并对经中鼻道上颌窦手术的主要术式进行了计算机建模，包括球囊鼻窦成形术、功能性鼻内镜鼻窦手术和钩突松动术。研究表明，计算机辅助球囊鼻窦成形术后上颌窦内气流速度增加。包括切除钩突在内的功能性鼻内镜鼻窦手术的计算机模拟显示了上颌窦与鼻腔之间的物质交换。
