RESUMO
BACKGROUND AND OBJECTIVES: Altough tonsillectomy is one of the most common otolaryngological procedures, a highly reliable and effective method for reducing postoperative pain has yet to be identified. This study evaluated the efficacy of a non-steroidal anti-inflammatory drug (NSAID) mouthwash on postoperative pain in tonsillectomy patients. SUBJECTS AND METHOD: A total of 64 patients who underwent tonsillectomy were randomly assigned to one of two groups (32 patients each). One group received the NSAID mouthwash and the other a distilled water mouthwash. Postoperative pain in the two groups was compared by assessing pain severity 1-9 days postoperatively using a visual analog scale. RESULTS: Compared to the distilled water mouthwash group, patients using the NSAID mouthwash showed a statistically significant decrease in postoperative pain over the first 9 postoperative days. CONCLUSION: A NSAID mouthwash may be a simple and effective method for controlling post-tonsillectomy pain when administered in conjunction with routine medications.
