首席研究员Richard J. Schwab博士说:“数字形态测量技术是一种准确、高流量、非侵入性的技术,可以识别解剖性OSA风险因素。”“形态测量学也可能提供更可重现性和标准化的Mallampati评分测量方法。”
A-C,分类摄影变量的示例。(a)修改后的Mallampati得分:示出了从照片P1获得的每个修改的Mallampati类的代表性示例。Class I表示UVULA和Tonsillar FOSTA的全部可见性。II类表明UVULA的上部的可见性和气道的部分可视性。III级表明硬腭和UVULA的基础的可见性。IV级表明硬腭的可见性,软腭的可见性。除了改进的Mallampati评分之外,我们还使用这些照片来派生气道可视性的衡量标准;在I级和II级,航空公司可见,但它不在III级和第四级。(b)舌头骑行。从照片P1,P2或P4,示出了缺失壁的缺失和证据的代表性示例。 If evidence of tongue ridging is visible in any frontal intraoral photo, subjects are then graded for presence of tongue ridging. (C) Pharyngeal narrowing. Representative examples of each grade of pharyngeal narrowing are shown, from photograph P1, P2, or P4. Grades are based on the location of the intersection between the palatopharyngeal arch and the tongue, relative to tongue width. Grade 1 indicates that the arch intersects at the edge of the tongue. Grades 2, 3, and 4 indicate that the palatopharyngeal arch intersects at 25%, 50%, and 75% or more of the tongue width, respectively. Credit:胸部
