Miyamoto Y, et al. - The impact of perioperative steroid use in patients undergoing tonsillectomy on the risk of postoperative bleeding requiring reoperation was assessed. Steroid use on the day of tonsillectomy was not associated with an increased risk of reoperation for bleeding. The possibility of increased risk, especially in children, was noted, however, the incremental risks of reoperation for steroid use were within an acceptable range for both adults and children. Safety of perioperative steroid use for tonsillectomy was supported, considering the magnitude of risk of reoperation because of bleeding.
