“Bilateral Sphenopalatine Ganglion Blockade with Bupivacaine Improves Early Postoperative Analgesia in Septorhinoplasty Surgeries: A Study”

https://pubmed.ncbi.nlm.nih.gov/38113753

The study found that bilateral sphenopalatine ganglion blockade (SPGB) with bupivacaine provides better analgesia in the early postoperative period after septorhinoplasty surgeries compared to a control group, but further studies are needed to confirm its impact on laryngospasm and nausea-vomiting.
