We evaluated the feasibility of ultrasonography for imaging of the trachea and its effectiveness in the diagnosis and follow-up of patients with tracheal stenosis due to various diseases. Twenty normal volunteers and six adult patients with tracheal stenosis were included in the study group. Subjects were examined with ultrasonography in a supine position with the neck hyperextended or in a sitting position. At the level of the thyroid isthmus, the anterior tracheal wall thicknesses imaged by ultrasonography were 1.54 +/- 0.22 mm (mean +/- SD) and 1.22 +/- 0.18 mm for normal male and female volunteers, respectively. Ultrasonography could reveal the intrinsic tracheal wall lesions and extrinsic lesions compressing the trachea in patients with tracheal stenosis. These ultrasonographic images correlated with CT images. In conclusion, ultrasonography may be useful in imaging of the trachea.
我们评估了超声检查对气管成像的可行性及其在诊断和随访各种疾病所致气管狭窄患者中的有效性。研究组纳入了20名正常志愿者和6名成年气管狭窄患者。受试者取仰卧位、颈部过伸或坐位接受超声检查。在甲状腺峡部水平，正常男性和女性志愿者超声成像的气管前壁厚度分别为1.54±0.22毫米（均值±标准差）和1.22±0.18毫米。超声检查可显示气管狭窄患者的气管壁内在病变以及压迫气管的外在病变。这些超声图像与CT图像相关。总之，超声检查可能有助于气管成像。
