Abstract：
Unilateral cleft lip and palate (UCLP) nasal deformity impacts airflow patterns and pressure distribution, leading to nasal breathing difficulties. This study aims to create an integrated approach using computer-aided design (CAD) and computational fluid dynamics (CFD) to simulate airway function and assess outcomes in nasal deformities associated with unilateral cleft lip and palate (UCLP) after LeFort I osteotomy advancement. Significant alterations were observed in nasal geometry, airflow velocity, pressure dynamics, volumetric flow rate, and nasal resistance postoperatively, indicating improved nasal airflow. The cross-sectional area increased by 26.6%, airflow rate by 6.53%, and nasal resistance decreased by 6.23%. The study offers quantitative insights into the functional impacts of such surgical interventions, contributing to a deeper understanding of UCLP nasal deformity treatment and providing objective metrics for assessing surgical outcome.
摘要：
单侧唇腭裂(UCLP)鼻畸形影响气流模式和压力分布,导致鼻呼吸困难.本研究旨在创建一种使用计算机辅助设计（CAD）和计算流体动力学（CFD）的综合方法，以模拟气道功能并评估LeFortI截骨术推进后与单侧唇裂和腭裂（UCLP）相关的鼻畸形的结果。观察到鼻部几何形状的显着改变，气流速度,压力动力学,体积流量,术后鼻腔阻力，显示鼻腔气流改善。横截面积增加了26.6%,气流率6.53%，鼻阻力下降6.23%。该研究提供了对此类外科手术干预的功能影响的定量见解，有助于加深对UCLP鼻畸形治疗的了解，并为评估手术效果提供客观指标。
