Moreover, it is often associated with significant bleeding due to the dense capillary network of the nasal region, making the maintenance of low-to-normal blood pressure preferable during surgery. Consequently, achieving stable hemodynamics and providing sufficient analgesia throughout the procedure is essential.\n\nThis study aims to evaluate the effects of bilateral maxillary nerve block on intraoperative remifentanil consumption and postoperative analgesic efficacy in patients undergoing Septorhinoplasty. A total of 90 patients will be included in the study. Forty-five patients (Group M) will undergo Septorhinoplasty under general anesthesia combined with bilateral maxillary nerve block, while the remaining 45 patients (Group N) will receive general anesthesia alone.\n\nIn the preoperative phase, a bilateral maxillary nerve block will be performed under ultrasound guidance via the pterygopalatine fossa. During the intraoperative period, total remifentanil consumption will be recorded, alongside assessments of hemodynamic stability, sevoflurane consumption, extubation time, intraoperative bleeding volume, and the satisfaction levels of both the anesthesiologist and the surgeon.\n\nIn the postoperative period, patient satisfaction, pain scores at 0, 1, 2, 4, 6, 12, 18, and 24 hours as well as at 1 month (measured using the Visual Analog Scale - VAS), additional analgesic requirements, and Quality of Recovery-15 (QoR-15) scores (assessed on preoperative day 1, postoperative day 1, and at 1 month) will be evaluated.",[28,29,30,31,32,33],"Head and Neck Surgery","Plastic Surgery","Rhinoplasty","Pain","Regional Anaesthesia","Nerve Blocks","RECRUITING","2025-11-17",{"date":37,"type":38},"2025-11-18","ACTUAL",{"date":40,"type":38},"2025-08-20",{"date":42,"type":22},"2026-12-08",{"name":44,"class":45},"Ankara Etlik City Hospital","OTHER_GOV"]
