Results: there was significant difference in intubation time and attempts among 3 groups (8.91.8, 10.71.7, 15.66.3 sec.p=.000; 1.20.5, 1.4 0.6, 1.70.8, p=.002 respectively). Failed intubations were 3, 4, 9 in three groups respectively, which was not statistically different (P=0.1). Conclusion: Due to fixed airway obstruction in patients with laryngeal tumors, FEV1 can be used as a predictor for classification and choosing a safe method for induction of anesthesia.
