A 19-year-old woman presented with attacks of dyspnea, wheezing and stridor. She had been treated for bronchial asthma with bronchodilators and corticosteroids without improvement. During episodes of wheezing, lung function tests were consistent with variable extrathoracic obstruction. Fiberoptic bronchoscopy confirmed that wheezing was due to paradoxical adduction of the vocal cords during the respiratory cycle. Clinical symptoms improved with speech therapy and psychological aid in relaxation. Vocal cord dysfunction is important in the differential diagnosis of bronchial asthma.
一名19岁女性出现呼吸困难、喘息和喘鸣发作。她曾使用支气管扩张剂和皮质类固醇治疗支气管哮喘，但病情无改善。在喘息发作期间，肺功能测试结果与可变的胸外梗阻一致。纤维支气管镜检查证实，喘息是由于呼吸周期中声带反常内收所致。经言语治疗和心理放松辅助后，临床症状有所改善。声带功能障碍在支气管哮喘的鉴别诊断中很重要。
