摘　　要：胸内型上气道阻塞性疾病通常缺乏特征性临床表现。回顾分析本院1990－1992年间肺功能检查共502例，发现其中有2例胸内型上气道阻塞的病例。其肺功能用力呼气流速容量曲线有特征性的呼气相平台，此法简便易行，具有较高诊断价值．There are no specific clinical menifestation in patients withintra-tho rax upper airway obstruction. Retrospectively analysing all the 206 cases of pulmonary function testing during the period of 1990 to 1992, we found 2 cases with intra -thorax upper-airway obstruction. The forced expiratory flow-volume curve showed charateristic plateau, which was different from the airway obstruction due to chronic obstructive pulmonary disease. The forced expiratory flow-volume curve was an easy and valuable testing in diferentiating intra -thorax upper airway obstruction from chronic obstructive pulmonary disease.
