The use of the flow-volume loop in assessing the results of laryngotracheal reconstruction

Gregor R.T. ; Plit M. ; Webster T. (1997)


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.
