In two patients with a goiter and respiratory symptoms occurring only in the recumbent posture, flow-volume loops (FVLs) were performed in various body postures: while sitting upright, supine, and left and right lateral decubitus. In both patients, flow rates, upper airway obstruction indices, and FVL morphologic features with patients in recumbent postures indicated the appearance of upper airway flow limitation with patients in the recumbent posture as compared with the upright posture. In the one patient who underwent thyroid surgery, these posture-related changes disappeared. We conclude that in patients with a goiter (or any extrinsic mass near to the upper airway), the comparison of FVLs performed in various body positions may help to clarify the origin of posture-related respiratory symptoms.
在两名患有甲状腺肿且仅在卧位时出现呼吸症状的患者中，于多种体位下进行了流量-容积环（FVL）检查：包括端坐位、仰卧位以及左侧和右侧卧位。在这两名患者中，与直立位相比，卧位时的流速、上气道阻塞指数以及FVL形态学特征均表明出现了上气道流量受限。在接受甲状腺手术的那名患者中，这些与体位相关的变化消失了。我们得出结论，对于患有甲状腺肿（或上气道附近任何外在肿物）的患者，在不同体位下进行FVL检查并加以比较，可能有助于明确与体位相关的呼吸症状的根源。
