There are few studies regarding the measurement of tracheal dimensions. Most are focused on morphology and tracheal development. The aim of this study was to determine the length and tracheal diameter of adults in our population and its correlation with external measurements.
The study design was prospective, observational and descriptive. We included a nonrandom sampling of deaths of Mexican national citizens who were between 18 and 65 year old. The study period was from June 1 to November 30, 2009, and the study was carried out at the facilities of the Forensic Medical Service of the Federal District, Mexico. Standardized measurements of tracheal diameter and length were correlated with external measurements.
We dissected 44 cadavers, 19 (43%) females and 25 (57%) males. In females the average age was 39.2 ± 13.9 years (range: 19-61 years), average height 161.9 ± 7.4 cm (range: 154-179 cm), tracheal length (TL) 8.6 ± 0.5 cm (range: 7.8-9.5 cm) and transverse diameter (TD) 1.7 ± 0.3 cm (range: 1.3-2.0 cm). Average age of males was 36.4 ± 14.4 years (range: 19-65 years), average height 169.8 ± 6.7 cm (range: 156-184 cm), TL 9.1 ± 0.9 cm (range: 8.0-10.7) and TD 1.9 ± 0.2 cm (range: 1.6-2.3 cm). TL was significantly correlated with sternal length (0.82, p <0.0001) and age (0.56, p = 0.0003). According to gender, there was no significant correlation between TL and height.
We found a low average TL and no significant correlation with height. These data should be considered when carrying out direct procedures on the trachea.
关于气管尺寸测量的研究较少。大多数研究集中在形态学和气管发育方面。本研究的目的是确定我们研究人群中成年人的气管长度和直径及其与外部测量值的相关性。
本研究设计为前瞻性、观察性和描述性研究。我们纳入了18至65岁的墨西哥公民死亡者的非随机样本。研究期间为2009年6月1日至11月30日，研究在墨西哥联邦区法医服务机构进行。气管直径和长度的标准化测量值与外部测量值相关。
我们解剖了44具尸体，其中19名（43%）为女性，25名（57%）为男性。女性的平均年龄为39.2±13.9岁（范围：19 - 61岁），平均身高161.9±7.4厘米（范围：154 - 179厘米），气管长度（TL）8.6±0.5厘米（范围：7.8 - 9.5厘米），横径（TD）1.7±0.3厘米（范围：1.3 - 2.0厘米）。男性的平均年龄为36.4±14.4岁（范围：19 - 65岁），平均身高169.8±6.7厘米（范围：156 - 184厘米），TL 9.1±0.9厘米（范围：8.0 - 10.7），TD 1.9±0.2厘米（范围：1.6 - 2.3厘米）。TL与胸骨长度显著相关（0.82，p <0.0001），与年龄也显著相关（0.56，p = 0.0003）。按性别划分，TL与身高之间无显著相关性。
我们发现气管平均长度较低，且与身高无显著相关性。在对气管进行直接操作时应考虑这些数据。
