在鼻中隔成形术和鼻中隔鼻成形术中提升粘膜软骨膜瓣时，提升软骨膜下层是重要的。当进行软骨膜下皮瓣提升时，外科医生使用色调的差异来区分软骨膜和软骨;然而，理解这些差异并与助手分享相对困难。此外，在尾端的软骨膜紧紧地粘附在软骨上，使得难以精确地分离软骨膜下层。窄带成像（NBI）是一种便于详细观察粘膜表层微血管的光学技术。在这项研究中，我们调查了NBI是否优于白色光（WL），在鼻中隔成形术和鼻中隔成形术中，在粘膜软骨膜瓣的提升中，NBI在突出软骨和软骨膜之间的对比度差异方面优于WL。（2例患者采用改良Killian入路，7例患者采用半横断入路，6例行开放性鼻中隔成形术），在WL内镜和NBI下观察鼻黏膜软骨膜瓣抬高的情况。使用ImageJ 1.53a比较WL和NBI之间的软骨膜和软骨的亮度以及两种组织之间的差异。接下来，WL和NBI的内窥镜图像用于软骨识别分为三个单独的红，绿色和蓝色的原色通道，和软骨膜和软骨的亮度分别测量为每个channel.ResultsUnder WL，软骨膜出现红白色和软骨出现白色，而根据NBI的软骨膜出现绿灰色，区分它从白色软骨。NBI上软骨和软骨膜之间的亮度差异（灰度差80.8（SD 42.4））明显高于WL成像（灰度差35.6（SD 31.1））（p<0.001）。在红色通道中，NBI上软骨和软骨膜之间的图像强度差异显著高于WL成像（红色WL灰度差-1.5（SD 33.7），红色NBI灰度差90.0（SD 56.7）;结论NBI在增强软骨与软骨膜之间的对比度方面优于WL。鼻中隔成形术和鼻中隔成形术中的软骨膜瓣。WL和NBI之间红光处理的差异对WL和NBI下软骨膜的软骨分化贡献最大。我们相信，NBI可以有效地应用于鼻中隔成形术和鼻中隔鼻成形术，以区分软骨膜与精确。
ObjectiveIn the elevation of the muco-perichondrium flap during septoplasty and septorhinoplasty, it is important to elevate the subperichondrial layer. When performing subperichondrial elevation of the flap, the surgeon uses differences in color tone to distinguish the perichondrium from cartilage; however, it is relatively difficult to understand these differences and to share them with assistants. Furthermore, the perichondrium at the caudal end adheres tightly to the cartilage, making it difficult to detach accurately the subperichondrial layer. Narrow band imaging (NBI) is an optical technology that facilitates detailed observation of microvessels in the mucosal surface layer. In this study, we investigated whether NBI is better than white light (WL) in accentuating differences in contrast between cartilage and perichondrium in the elevation of the muco-perichondrium flap during septoplasty and septorhinoplasty.MethodsTwenty-six sides of 15 patients (the modified Killian approach was used in two patients, the hemitransfixion approach was used in seven patients, and open septorhinoplasty was used in six patients) with elevated muco-perichondrium flaps were studied under WL endoscopy and NBI. The brightness of the perichondrium and cartilage and the differences between the two tissues were compared between WL and NBI using ImageJ 1.53a. Next, the WL and NBI endoscopic images used for cartilage identification were divided into the three separate primary color channels of red, green, and blue, and the brightness of the perichondrium and cartilage were measured separately for each channel.ResultsUnder WL, the perichondrium appeared reddish-white and the cartilage appeared white, whereas under NBI the perichondrium appeared greenish-gray, differentiating it from the white cartilage. The difference in brightness between the cartilage and perichondrium was significantly higher on NBI (grayscale difference 80.8 (SD 42.4)) than on WL imaging (grayscale difference 35.6 (SD 31.1)) (p<0.001). In the red channel, the difference in image intensity between cartilage and perichondrium was significantly higher on NBI than on WL imaging (Red WL grayscale difference -1.5 (SD 33.7), Red NBI grayscale difference 90.0 (SD 56.7); p<0.001).ConclusionsNBI is better than WL at accentuating the difference in contrast between cartilage and the perichondrium during the elevation of the muco-perichondrium flap during septoplasty and septorhinoplasty. The difference in the processing of red light between WL and NBI provides the largest contribution to the differentiation of cartilage from the perichondrium under WL and NBI. We believe that NBI can be usefully applied during septoplasty and septorhinoplasty to distinguish cartilage from the perichondrium with precision.
