    BackgroundThe objective of this study was to assess the impact of preoperative sphenopalatine ganglion block (SPGB) on postoperative pain and assess intraoperative and postoperative analgesic consumption in patients undergoing septorhinoplasty.MethodsIn this prospective, randomized controlled study, 72 patients were included and divided into two groups: group 1 (36 patients) received the sphenopalatine ganglion block (SPGB), while group 2 (36 patients) served as the control group. Patient assessments, using the numerical rating scale (NRS), were conducted at the postoperative first hour, fourth hour, and 24th hour. Additionally, intraoperative hemodynamics, analgesic requirements, and postoperative analgesic requirements were documented.ResultsThe patients in group 1 exhibited significantly lower NRS scores at postoperative first, fourth, and 24th hour than those in group 2 (P<0.001 for all three time points). Additionally, the mean Riker Sedation-Agitation Scale (RSAS) scores were significantly lower in group 1 than in group 2 (P=0.006). Both intraoperative remifentanil use and postoperative analgesic consumption were significantly higher in patients in group 2 (P<0.001 and 0.004, respectively) than those in group 1. Analysis of intraoperative heart rate and mean arterial pressure (MAP) revealed that patients in group 1 had lower postoperative heart rates (P=0.040) than those in group 2, and MAP values after intraoperative block, at 30 min, and postoperatively were significantly lower (P=0.005, P=0.001, and P=0.034, respectively) than those in group 2.ConclusionsWe advocate for the adoption of the noninvasive SPGB method in patients undergoing septorhinoplasty surgery. This approach significantly reduces the need for intraoperative analgesics, alleviates postoperative pain, and reduces the demand for postoperative analgesics. Moreover, it improves the overall surgical experience because of its ease of application, contributing to a more comfortable surgical process.
