Background and Aims Pain management is crucial to decrease postoperative adverse events after septorhinoplasty surgery. Although the beneficial effects of infraorbital and infratrochlear nerve block for nasal surgeries have been studied, it’s effect on opioid consumption has not been evaluated. Our aim was to investigate primarily the effect of infraorbital and infratrochlear block on remifentanil consumption hence the postoperative nausea/vomiting related to opioid consumption and need for rescue analgesia.

Methods In this prospective, randomised controlled study, 62 patients undergoing elective septorhinoplasty surgery were randomised in to two groups: Control group (without nerve blockade) and Block group (bilateral ultrasound guided infraorbital block and infratrochlear block). BIS monitorization was utilised for all patients in both groups for standardization.The scores of Richmond agitation sedation(RASS), Numerical rating scale(NRS), Boezaart bleeding and also nausea, vomiting, remifentanil consumption and the duration of the surgery were recorded.

Results NRS score, remifentanil consumption and nausea were statisticaly lower (p<0.001) in Block group, while the patients in Control group were observed drowsy according to RASS score. Rescue analgesia was statistically high in Control group (p<0.001).

Conclusions Ultrasound guided bilateral infraorbital block and infratrochlear nerve block can be considered in patients undergoing septorhinoplasty surgery, due to it’s reducing effect on perioperative remifentanil consumption hence side effects of opioid consumption and postoperative pain.
