Abstract

The computed tomography (CT) details of the dimensions of the trachea and the subglottic area are not fully covered in the literature, so it is important to build up a database for the CT measurements of that area. Preoperative details of the trachea are crucial prior to any approach or procedure involving the trachea. So, the aim of this study was to determine the different dimensions of the trachea and subglottic area by computed tomography (CT). From 100 CTs of the trachea acquiring the axial images via the multiplanar reformates for all subjects to get the delicate details measuring the transverse diameter (width) and the anteroposterior diameter (depth) of the trachea and subglottic area. The mean tracheal width was 15.5 ± 2.1 mm (range = 11.5–21.7), and its mean anteroposterior diameter was 16.56 ± 2.77 mm (range = 11.8–25.1), while the mean width of the subglottic area was 15.1 ± 1.86 mm (range = 12.3–21.1), and its mean anteroposterior diameter was 17.75 + 2.76 (range = 12.9–25.2). All the dimensions of the trachea and the subglottic area were found significantly smaller in female than males. There was positive correlation between anteroposterior and transverse diameters of the trachea with the subglottic area with more tendency for more subglottic area dimension with increase tracheal dimensions and vice versa. The current work updates the CT knowledge about the tracheal and subglottic area dimensions enhancing the surgeons, anesthetist, and radiologists data and orientation of the tracheal dimensions and could aid effective and safe tracheolaryngeal surgery.

气管和声门下尺寸:一项针对成年人群的计算机断层扫描横截面研究
有关气管和声门下区域尺寸的计算机断层扫描(CT)细节在文献中并没有完全涉及,因此建立一个该区域的 CT 测量数据库非常重要。在任何涉及气管的方法或手术之前,气管的术前细节至关重要。因此,本研究旨在通过计算机断层扫描(CT)确定气管和声门下区域的不同尺寸。通过对所有受试者的 100 张气管 CT 进行多平面重整,获取轴向图像,以测量气管和声门下区域的横向直径(宽度)和前后直径(深度)的精细细节。气管的平均宽度为 15.5 ± 2.1 毫米(范围 = 11.5-21.7),平均前胸直径为 16.56 ± 2.77 毫米(范围 = 11.8-25.1),声门下区的平均宽度为 15.1 ± 1.86 毫米(范围 = 12.3-21.1),平均前胸直径为 17.75 + 2.76(范围 = 12.9-25.2)。女性气管和声门下区的所有尺寸均明显小于男性。气管的前后径和横径与声门下区之间呈正相关,气管尺寸越大,声门下区尺寸越大,反之亦然。目前的工作更新了 CT 对气管和声门下区尺寸的认识,增强了外科医生、麻醉师和放射科医生对气管尺寸的数据和定位,有助于有效和安全地进行气管喉手术。
