Sphenopalatine ganglion block for pain control after septoplasty: a systematic review and meta-analysis with trial sequential analysis

Septoplasty corrects a deviated nasal septum (DNS) and improves nasal obstruction. Sphenopalatine ganglion block (SPGB) effectively reduces postoperative pain after septoplasty, but conclusive evidence is still lacking. This systematic review and meta-analysis aim to comprehensively evaluate the analgesic efficacy of SPGB in septoplasty patients.
