目的：探讨解剖光学相干断层扫描(AOCT)在评估鼻内瓣膜(INV)中的应用价值。使用CT成像和aOCT对新鲜采集的人体标本头部进行评估。扫描在3个时间点进行：1)间隔成形术后获取软骨，2)放置蝶骨移植(BFG)，3)放置双侧扩张器移植(SG)。然后，成像数据被转换成鼻腔的3D模型。通过静态容量分析和计算流体动力学(CFD)对CT和aOCT生成的模型进行比较，以预测鼻腔阻力和压力。使用aOCT的扫描显示，在干预前后的体积参数方面，结果与CT相似。CFD对aOCT数据的分析显示，在SG或BFG干预后，压力降低。当比较CT和aOCT产生的压力或阻力计算时，没有发现统计学上的显著差异。使用aOCT技术，可以静态成像鼻瓣膜。与传统的CT成像相比，其优点包括不受辐射照射，扫描速度快。此外，随着OCT技术的发展，在办公室使用也是可能的。有必要进行进一步的研究，以确定aOCT在动态评估鼻气道这一重要组成部分中的作用。(三)
To establish the utility of anatomic optical coherence tomography (aOCT) in evaluating internal nasal valve (INV). Fresh harvested human specimen heads were evaluated using both CT imaging as well as using aOCT. Scans were performed at 3 time points: 1) after septoplasty for cartilage harvest, 2) after placement of butterfly graft (BFG), and 3) after placement of bilateral spreader grafts (SG). Imaging data were then converted into 3D models of the nasal airway. CT and aOCT-generated models were compared by both static volumetric analysis and computational fluid dynamics (CFD) to predict nasal resistance and pressure. Scans using aOCT showed comparable results to CT in terms of volumetric parameters both before and after intervention. Analysis of aOCT data by CFD demonstrated decrease in pressure after SG or BFG intervention. No statistically significant difference was observed when comparing CT and aOCT-generated calculations of pressure or resistance. The internal nasal valve can be imaged in a static fashion using aOCT technology. Advantages over traditional CT imaging include lack of exposure to radiation and rapid scan time. In addition, in-office use is possible as aOCT technology develops. Further investigation will be necessary to define the role of aOCT in the dynamic evaluation of this vital component of the nasal airway. III
