摘要

目的:本研究旨在确定矫正鼻中隔尾端偏曲的客观手术指征。方法:我们采用定量计算机断层扫描(CT)分析,并通过将其与前鼻镜(AR)结果进行比较来评估有效性。研究人群包括300名患者。将存档的CT数据传输到工作站,使用计算机图形工具生成三维CT体渲染图像。在鼻孔入口平面内,我们计算出凸侧(窄侧)与凹侧(宽侧)的横截面积之比,简称为N/W比。我们还根据AR检查了鼻阀左右横截面积之间的偏侧。根据AR检查结果和N/W比计划是否暴露尾端手术。结果:AR表现与N/W比值有显著相关性。术后平均N/W比由0.53±0.15提高到0.81±0.15,鼻塞VAS评分由8.1±0.2提高到1.0±0.1。结论:本研究提出的定量CT分析是客观确定鼻中隔尾端处理手术指征的有效方法。

An Evaluation of the Caudal End Deviation of the Nasal Septum Using the Quantitative Analysis of Computed Tomography
Objectives: This study was designed to determine objective surgical indications of correcting caudal end deviation of the nasal septum. Methods: We employed quantitative computed tomographic (CT) analysis and assessed the validity by comparing this with anterior rhinoscopic findings (AR findings). The study population consisted of 300 patients. The archived CT data were transferred to a workstation, and 3D CT volume-rendered images were generated using computer graphics tools. In the plane of the nostril entrance, we calculated ratios of the cross-sectional area of the convex side (narrower side) and the concave side (wider side), which is abbreviated as the N/W ratio. We also examined the presence of laterality between the right and the left cross-sectional area of the nasal valve based on the AR findings. Surgical procedures for whether to expose the caudal end were planned based on the AR findings and the N/W ratio. Results: A significant correlation was found between the AR findings and the N/W ratio. After surgery, the average N/W ratio improved from 0.53 ± 0.15 to 0.81 ± 0.15, and the average values of VAS scaling for nasal obstruction improved from 8.1 ± 0.2 to 1.0 ± 0.1. Conclusions: The quantitative CT analysis proposed in the study is a useful modality to objectively determine the surgical indications of managing the caudal end of the nasal septum.
