Overview
This randomized, controlled clinical trial will evaluate the clinical effects of a topical thermoresponsive hydrogel containing dexamethasone sodium phosphate and diclofenac sodium on postoperative pain and facial swelling in patients undergoing extraoral maxillofacial surgical procedures or primary closure of clean facial soft tissue wounds. Participants will be stratified according to fracture status and randomly assigned to receive either the active hydrogel or an identical placebo hydrogel. Pain, facial swelling, wound healing, adverse events, patient satisfaction, and rescue analgesic consumption will be evaluated during the postoperative period.
