Efficacy of Tenoxicam, Paracetamol, and Their Combination in Postoperative Pain After Double-Jaw Surgery.

Introduction Orthognathic surgical procedures include a series of surgical operations in which interventions are applied to the maxilla, mandible, or both for occlusal or aesthetic concerns due to facial skeletal development deformities. Double-jaw surgeries have the highest pain scores, in which both maxilla and mandible bones are intervened. This study aimed to compare the efficacy of individual applications of paracetamol and tenoxicam with their combined application on postoperative pain and opioid consumption in patients undergoing double-jaw surgery. Methods In this randomized, double-blind study, 60 patients undergoing double-jaw surgery were allocated into three groups, with each having 20 patients: the paracetamol group, the tenoxicam group, and the paracetamol-tenoxicam combination group. Pain intensity was evaluated using the visual analogue scale (VAS) at intervals of 30 minutes, 60 minutes, 120 minutes, and again at the 24th postoperative hour. Additionally, the consumption of opioids and other rescue analgesics was documented over the 24-hour postoperative period. Results The VAS values at 30 minutes, 60 minutes, and 24 hours were lower in the paracetamol-tenoxicam group compared to the other groups (p<0.001). The need for a rescue analgesic drug in the first 24 hours was not observed in the tenoxicam and paracetamol-tenoxicam groups. Conclusion It was concluded that both tenoxicam and paracetamol-tenoxicam combinations, especially the tenoxicam-paracetamol combination, were good options for postoperative analgesia in patients with double-jaw surgery.
