Group 1 underwent nasal fibroscopy without vasoconstriction or local anesthesia with an endosheath\u2010 protected endoscope. Group 2 was examined by a fiberscope without an endosheath after application of naphazoline Xylocaine. Each OC was divided in 16 items recorded as visualized or not. Four scores were compared between both groups: out of 16 (1 side), out of 32 (both sides), out of 12 concerning only the narrowest and highest bilateral spaces, and out of 4 to divide these specific areas in anterior, middle, and posterior parts.
