Oral flurbiprofen spray for postoperative sore throat and hoarseness: a prospective, randomized, double-blind, placebo-controlled study.

Background: Sore throat and hoarseness are common complications after surgery. Flurbiprofen spray has been successfully used for treatment of oral inflammations, but its effects on postoperative sore throat and hoarseness are unknown. We conducted this study to evaluate the effectiveness of flurbiprofen spray on postoperative sore throat and hoarseness, by comparing it with benzydamine hydrochloride spray and placebo.
