Flow volume spirometry as a test for postoperative airway evaluation following arytenoidectomy.

The postoperative upper airway of nine patients who had undergone Woodman procedures for bilateral vocal cord paralysis were assessed by means of flow volume spirometry using the FIF-50 measurement expressed in percentage of normal. There appears to be a good correlation between the postoperative FIF-50 and the degree of postoperative subjective laryngeal obstruction.
