The effectiveness of preemptive sphenopalatine ganglion block on postoperative pain and functional outcomes after functional endoscopic sinus surgery

Abstract

A limited trend toward reduced postoperative pain after FESS was noted with bupivacaine compared to saline, but statistical significance was not achieved. Preemptive SPGB may offer sinonasal symptomatic benefits for patients undergoing FESS, but larger studies are warranted.

Role of local anaesthetic nerve block in endoscopic sinus surgery: A systematic review and meta‐analysis

“…The difference in mean pain scores was 0.36 in favour of LAB group ( P = .009). Cho et al did not observe difference in pain scores …”

“…Data addressing this comparison were available from three studies . However, only two studies were pooled into meta‐analysis .…”

“…I 2 was 84%, suggesting significant heterogeneity (χ 2 = 6.73, P = .22). The remaining study by Cho et al did not show a difference between the two groups …”

“…The sphenopalatine ganglion nerve block is used to treat facial pain, headache of various aetiologies, and non‐malignant and malignant neck pain . In ESS, there are several randomised controlled trials evaluating the role of LAB, however, these studies have reported conflicting results …”

Noninvasive Sphenopalatine Ganglion Block for Acute Headache in the Emergency Department: A Randomized Placebo-Controlled Trial

“…[8][9][10][11][12] Sphenopalatine ganglion block has been described for treatment of facial and head pain, including cluster headaches, trigeminal neuralgia, and postoperative pain relief for ear, nose, and throat surgeries. [13][14][15][16][17] Recent evidence has implicated the sphenopalatine ganglion as an important neural relay point for common migraine. [8][9][10][11][12] Activation of the sphenopalatine ganglion causes parasympathetic-mediated vasodilation of the cerebral vasculature, producing cephalgia.…”
