The difficult problem of assessing pre- and postoperative airway function in patients with laryngotracheal upper airway obstruction is discussed. A series of 26 patients with various forms of this problem is presented. The method of performing the flow-volume loop (FVL) is described and the theory behind the investigation is reviewed. Five of the series of 26 patients are described in detail as examples, and the advantages and disadvantages of this investigation are discussed fully. The FVL appears to be the only really objective test to assist the laryngotracheal reconstructive surgeon. It is easily performed in most cases and should form part of the diagnostic and postoperative workup.
本文讨论了评估喉气管上呼吸道梗阻患者术前和术后气道功能的难题。介绍了一系列26例患有各种形式此类问题的患者。描述了进行流量-容积环（FVL）的方法，并回顾了该检查背后的理论。详细描述了这26例患者中的5例作为示例，并充分讨论了该检查的优缺点。FVL似乎是协助喉气管重建外科医生的唯一真正客观的检查。在大多数情况下，它易于实施，应成为诊断和术后检查的一部分。
