鼻瓣区的客观测量对评价功能性鼻整形手术效果有重要价值。解剖光学相干断层扫描（aOCT）是一种成像模式，可用于获得鼻气道的实时、定量和体积扫描。我们的目的是评估容积aOCT成像是否适用于功能性鼻整形手术前后的鼻瓣膜区域检查。在撑开移植物和蝶形移植物手术之前和之后，对四个尸体头部进行鼻瓣膜的aOCT扫描。将得到的aOCT图像与视频内窥镜图像进行比较，并将从aOCT扫描获得的鼻气道分割体积与在相同条件下采集的计算机断层扫描（CT）衍生体积进行比较。aOCT导出的体积与CT体积紧密匹配，平均Dice相似系数为0.88，平均Hausdorff距离为2.3 mm。此外，aOCT图像准确地代表了鼻腔的形状。由于其能够对鼻气道进行实时、定量和准确的评估，aOCT成像是一种有前途的方法，可用于在功能性鼻整形术前后客观评估鼻瓣膜。(C)作者。由SPIE在知识共享署名4.0未移植许可下发布。
Objective measurement of the nasal valve region is valuable for the assessment of functional rhinoplasty surgical outcomes. Anatomical optical coherence tomography (aOCT) is an imaging modality that may be used to obtain real-time, quantitative, and volumetric scans of the nasal airway. We aim to evaluate if volumetric aOCT imaging is useful for the examination of the nasal valve region before and after functional rhinoplasty procedures. aOCT scans of the nasal valves were performed on four cadaveric heads before and after spreader graft and butterfly graft procedures. The resulting aOCT images were compared against video endoscopy images, and the segmented volumes of the nasal airway obtained from aOCT scans were compared with computed tomography (CT) derived volumes acquired under the same conditions. The aOCT-derived volumes match the CT volumes closely, with a mean Dice similarity coefficient of 0.88 and a mean Hausdorff distance of 2.3 mm. Furthermore, the aOCT images were found to represent the shape of the nasal cavity accurately. Due to its ability to perform real-time, quantitative, and accurate evaluation of the nasal airway, aOCT imaging is a promising modality for the objective assessment of the nasal valves before and after functional rhinoplasty procedures.
