The Effect of Sphenopalatine Ganglion Block on the Postoperative Pain in Patients Undergoing Septorhinoplasty.

This study aimed to evaluate the effect of preoperative sphenopalatine ganglion block (SPBG) on the postoperative pain (POP) in patients undergoing septorhinoplasty (SRP). A retrospective cohort study was performed. A total of 42 patients that had received septorhinoplasty included in the study. The patients that had received SPBG before the surgery included in the Block group (n:20) and the patients that had not received SPBG before the surgery included in the Control group (n:22). POP was questioned with a numeric rating scale (NRS) at the 30th minute (t1), 1st hour (t2), 4th hour (t3), 12th hour (t4), and 24th hour (t5) and noted. The intraoperative details and the dose of the postoperative rescue analgesics were also noted. The average dose of Paracetamol that was used in the postoperative first 24 hours was 500 mg in the Block group and 1363 mg in the Control group, and the difference was statistically significant ( Preoperative SPGB is an effective option to reduce POP and the need for rescue analgesics for patients undergoing SRP.
