1Department of Otolaryngology-Head and Neck Surgery, University of Virginia, Charlottesville, VA 22908-0713, USA.
Purpose:
To determine the effectiveness of perioperative local anesthesia in tonsillectomy patients.
Design:

Results:
Thirty-four adults agreed to participate in the study over a 2-year period, with 20 patients returning completed questionnaire forms. Regarding pain intensity over a 10-day period, oral analgesic use after surgery, and oral intake after surgery, there were no differences between the two groups, with P values of .25, .32, and .34, respectively.
Conclusion:
The effect of perioperative local marcain infiltration in tonsillectomy patients was similar to placebo.
