背侧保留式鼻整形术中的鼻气流变化：人体解剖标本的计算流体动力学分析

文献信息

中文摘要

背景： 既往研究已探讨背侧保留式鼻整形术对鼻气流尤其是内鼻瓣的影响，结果不一。
目的： 利用计算流体动力学在人体解剖模型中评估背侧保留式鼻整形术对鼻气流的影响。
方法： 这是一项比较研究，对四具新鲜人体解剖标本进行解剖，并使用锥形束CT扫描仪评估各种手术干预（必要时行鼻中隔成形术以及背侧保留式鼻整形术）对鼻气流的影响。
结果： 总体而言，鼻中隔成形术和背侧保留式鼻整形术技术均呈现鼻阻力下降的趋势。除一具标本外，背侧保留式鼻整形术降低了所有人体解剖标本的鼻阻力。
结论： 在人体解剖标本研究中，有证据表明背侧保留式鼻整形术技术可降低鼻阻力，这种降低可能部分因上外侧软骨解剖在顶端内鼻瓣处的方向而异。

英文摘要

BACKGROUND: Prior studies have looked at the impact of dorsal preservation rhinoplasty on nasal airflow, specifically the internal nasal valve, with mixed results.
OBJECTIVE: To use computational fluid dynamics to assess the impact of dorsal preservation rhinoplasty on nasal airflow in a human anatomic model.
METHODS: This was a comparative study using anatomic dissection of four fresh human anatomic specimens using a cone beam CT scanner to assess various surgical interventions (septoplasty, if necessary, and dorsal preservation rhinoplasty) on nasal airflow.
RESULTS: Overall, there was a trend of decreased nasal resistance across septoplasty and dorsal preservation rhinoplasty techniques. Dorsal preservation rhinoplasty decreased nasal resistance for all human anatomic specimens, except for one.
CONCLUSION: There is evidence of reduction in nasal resistance in a human anatomic specimen study with dorsal preservation rhinoplasty techniques, which can vary, in part, by the orientation of upper lateral cartilage anatomy at the apical internal nasal valve.
