内鼻瓣膜受损是鼻阻塞的主要原因，治疗这种情况的方法越来越多。在这项研究中，我们比较了蝶形移植物、扩张移植物和生物可吸收鼻植入物对鼻气流阻力的影响。计算流体动力学（CFD）模拟完成了9个术前和术后尸体受试者。对每个尸头植入生物可吸收鼻植入物（BNI，Spirox Latera，斯特赖克ENT，Plymouth，MN）、蝶形移植物或扩张器移植物。术前和术后CT扫描用于生成鼻气道的三维（3D）模型，用于吸气期间气流和热传递的稳态CFD模拟。蝶形移植物放置导致鼻气道阻力平均改善24.9%（+/− 7.3），而BNI放置导致6.7%（+/− 1.2）改善，扩张器移植物放置也导致2.6%（+/− 13.5）的持续改善。蝶形移植物放置后主鼻腔内的压力始终低于扩张器移植物或BNI。蝶形和扩张移植物放置也导致气流分配的适度改善，而BNI表现出更多的变化（-1%至12%）。热通量没有显著差异;然而，在所有三种干预措施下，总热通量略有改善。本研究的结果表明，在所有三种手术干预中，鼻气道阻力均有所降低，蝶形移植物优于其他两种技术。然而，这些数据仅反映了静态环境，而不是呼吸期间所见气流的动态变化。
Internal nasal valve compromise is a major cause of nasal obstruction with a growing number of ways to treat this condition. In this study, we compared the effects of butterfly graft, spreader graft and the bioabsorbable nasal implant on nasal airflow resistance. Computational fluid dynamics (CFD) simulations were completed from nine pre-operative and post-operative cadaveric subjects. Each cadaveric head underwent placement of a bio-absorbable nasal implant (BNI, Spirox Latera, Stryker ENT, Plymouth, MN), butterfly graft, or spreader graft. Pre- and post-operative CT scans were used to generate three-dimensional (3D) models of the nasal airway used in steady state CFD simulations of airflow and heat transfer during inspiration. Butterfly graft placement resulted in a mean improvement in nasal airway resistance of 24.9% (+/− 7.3), while BNI placement resulted in a 6.7% (+/− 1.2) improvement, and spreader graft placement also resulted in a consistent improvement of 2.6% (+/− 13.5). Pressure within the main nasal cavity was consistently lower following butterfly graft placement versus a spreader graft or BNI. Butterfly and spreader graft placement also resulted in modest improvements in airflow allocation, while BNI demonstrated more variation (−1 to 12%). Heat flux was not significantly different; however, a small improvement in total heat flux was seen with all three interventions. The results of this study demonstrate reduction in nasal airway resistance in all three surgical interventions, with the butterfly graft demonstrating superiority to the other two techniques. However, these data only reflect a static environment and not dynamic changes in airflow seen during respiration.
