摘　　要：目的探讨颈段气管软骨良性病变的体外高频超声表现特点及其临床意义。方法回顾性分析2011年1月-2016年12月我院经病理及气管镜、CT检查明确为复发性多软骨炎呼吸道受累患者4例，以及经口/鼻插管后颈段气管狭窄患者30例，应用体外高频超声观察各个受累气管软骨的声像表现，测量病变气管软骨厚径，并以对应气管软骨的CT厚度测值为对照。结果34例患者均获得颈段气管软骨良性病变声像图以及软骨厚度测值，共计85个回声异常的颈段气管软骨，其中复发性多软骨炎呼吸道受累者占20个（24％），经口／鼻插管后颈段气管狭窄者占65个（76％）。85个病变气管软骨厚度范同：超声测值范同是1．0～7．0mm，均值为（2．2±O．86）mm，CT测值范围是0．9～7．2mm，均值为（2．3±0．91）mm，两组间比较差异无统计学意义（P〉0．05）。结论体外高频超声可以清晰显示气管重要支撑结构气管软骨的细微结构变化和测量软骨厚度，有望成为评估颈段气管支撑结构和疗效方法的一种有价值的辅助手段。Objective To investigate the characteristics and clinical significance of extracorporeal high-frequency uhrasonography （EHFUS） in benign lesions of cervical tracheal cartilage. Methods A retrospective analysis was conducted for four cases of recurrent polychondritis with respiratory tract involvement confirmed by pathology, bronchoscopy and CT scanning, as well as 30 cases of cervical tracheal stenosis after oral/nasal intubation in our hospital between January 2011 and December 2016. EHFUS was used to determine the ultrasonographic manifestations and measure the thickness of each affected tracheal cartilage. The corresponding thickness of tracheal cartilage measured on CT was used as a control. Results All the 34 patients successfully underwent acquisition of ultrasonography and thickness measurement of cervical tracheal cartilages. In total, 85 cervical tracheal cartilages were identified to be sonographically abnormal, including 20 （24%） from 4 cases of recurrent polyehondritis with respiratory tract involvement, and 65 （76%） from 30 cases of mouth/nasal intubation-induced cervical tracheal stenosis. The thickness of tracheal cartilage in 85 lesions ranged from 1.0 to 7.0 mm with a mean of （2.2 ± 0.86） mm on EHFUS, and from 0.9 to 7.2 mm with a mean of （2.3 ± 0.91） mm on CT, respectively, with no statistically significant difference between the both （P〉 0.05）. Conclusion EHFUS may offer clear display of structural changes and thickness measurement of the cervical tracheal cartilages, and is therefore promising as a valuable aid to assess the major support architecture of the cervical trachea and therapeutic efficacy in tracheal lesions.
