Injection of local anesthetic significantly benefits patients undergoing tonsillectomy.
Tonsillectomy is a commonly performed procedure in the United States and is usually associated with significant postoperative pain. The benefits of decreased pain are obvious; a shorter recovery period and faster return to a regular diet and activity level make life much easier for patients and their families. Numerous attempts have been made to reduce postoperative pain; these include improved intraoperative anesthetic pain regimens, use of corticosteroids, adjustment of surgical technique, and intraoperative injection of local anesthetic.
