摘要

本研究使用CFD分析了一名14岁单侧上颌不完全性裂女孩手术前、植骨后和正畸治疗后三个阶段的上呼吸道气流。结果发现上颌裂对气道容积有影响。术后和正畸治疗后，气道横截面积改变，鼻咽/口咽湍流减少；正畸后1年鼻气流速度归一化（5.032 m/s vs.健康青少年5.024 m/s）；从鼻孔到咽部的总压降为20.64 Pa，接近健康青少年的20.69 Pa。这些结果表明治疗后呼吸功能恢复正常。

The changes of upper airway flow in adolescents with maxillary cleft before and after bone grafting and orthodontic treatment: a CFD simulation study.

This study used CFD to analyze upper airway airflow in a 14-year-old girl with a unilateral incomplete maxillary cleft across three stages: before surgery, after bone grafting, and after orthodontic treatment. Results revealed that the maxillary cleft affected the airway volume. Post-surgery and orthodontics, airway cross-sectional areas changed and turbulence in nasopharynx/oropharynx reduced; One year post-orthodontics, nasal airflow velocity normalized (5.032 m/s vs. healthy adolescents' 5.024 m/s); the shear stress distribution improved, and total pressure drop from the nostrils to the pharynx was 20.64 Pa, close to healthy adolescents' 20.69 Pa. These findings indicate that respiratory function normalized after treatment.
