This prospective, randomized, double-blind clinical trial aims to compare the postoperative analgesic efficacy and recovery outcomes of infraorbital-infratrochlear nerve block and transnasal sphenopalatine ganglion block in patients undergoing septorhinoplasty under general anesthesia. Adult patients aged 18-65 years with ASA I-II status will be randomized to receive either bilateral infraorbital-infratrochlear block or transnasal sphenopalatine ganglion block after induction of anesthesia. Postoperative outcomes including pain scores (NRS at 0-2 h, 2-8 h, and 8-24 h), emergence agitation, Riker Sedation-Agitation Scale (RSAS) scores, time to first rescue analgesic, total tramadol consumption, adverse events, surgical site complications, and patient satisfaction will be assessed and compared between groups.
