Abstract
Background
This study evaluated the effect of bilateral endoscopic sphenopalatine ganglion block (SPGB) for management of postoperative pain in patients undergoing septoplasty.

Methods
Sixty septoplasty patients (51.7% male, 48.3% female, aged 18 to 45 years) were randomly assigned to general anesthesia (GA) alone (control) (n = 30) or GA plus endoscopic SPGB (n = 30). Demographic data, duration of surgery, blood loss, postoperative visual analogue scale (VAS) pain scores (upon arrival at the postanesthesia care unit [PACU] and 2, 6, 12, and 24 hours after surgery), overall analgesic usage (end of 24 and 168 hours after surgery), overall satisfaction with the pain control (end of 24 and 168 hours after surgery), and complications (bleeding, nausea and vomiting, and visual disturbance) were recorded.

Results
Pain scores upon arrival to the PACU and 2, 6, 12, and 24 hours after surgery were significantly lower in the SPGB group compared to the control group (p < 0.001). Moreover, the SPGB group had significantly lower analgesic requirements and higher satisfaction scores with their pain control at the end of 24 and 168 hours after surgery compared to the control group (p < 0.001). The 2 groups significantly differed in terms of intraoperative blood loss (p = 0.024), and surgery time was longer in the SPGB group compared to the control group (p < 0.001).

Conclusion
SPGB with bupivacaine is a safe and effective method to reduce pain after septoplasty, and it is a cost‐effective alternative to high doses of analgesics.
