Functional airway obstruction is an uncommon condition that must be considered in adults with apparent airway distress. The disorder is characterized by stridor without abnormal physical findings on laryngeal examination other than intense vocal cord adduction. Three patients had functional upper airway obstruction documented by objective criteria. In each case the respiratory embarrassment was severe enough to warrant tracheostomy. A thorough search for systemic causes did not reveal an organic etiologic factor. Psychiatric evaluation demonstrated psychological disorders in each case. Functional airway obstruction represents an important consideration in the differential diagnosis of airway obstruction in the adult.
功能性气道梗阻是一种罕见病症，对于出现明显气道窘迫的成年人必须予以考虑。该病症的特点是除了声带强烈内收外，喉部检查无异常体征却伴有喘鸣。三名患者经客观标准证实存在功能性上气道梗阻。在每例中，呼吸窘迫都严重到需要行气管切开术。全面排查全身性病因未发现器质性病因。精神科评估显示每例均存在心理障碍。功能性气道梗阻是成人气道梗阻鉴别诊断中的一个重要考量因素。
