We aimed to investigate the effects of bilateral sphenopalatine ganglion blockade (SPGB) on postoperative early complications in septorhinoplasty operations.

INTERVENTION: Sphenopalatine group (Group S, n=40). It was applied with infiltration anesthesia to both groups by the same otolaryngologist with the Sphenocath device(SphenoCath Applicator; Dolor Technologies, Scottsdale, Arizona). SPG blockade was performed by a otolaryngologist blinded to the drug used. Patients in group S were performed bilaterally with 2 mL of 0.025% adrenalin‐free intranasal bupivacaine (Marcaine 0.5% vial, Astra‐Zeneca, Germany) 15 minutes before the end of the operation. The results were evaluated by an anesthesiologist who was not involved in the study. In the recovery unit after the operation; The pain and analgesic needs of the patients at 0, 2, 6 and 24 hours were evaluated. The presence of laryngospasm and the frequency of nausea and vomiting in the first 24 hours were recorded during the recovery period. CONDITION: Anaesthesiology ‐ Pain management Respiratory ‐ Other respiratory disorders / diseases septum deviation;sphenopalatine ganglion blockade ; ; septum deviation ; sphenopalatine ganglion blockade Surgery ‐ Other surgery PRIMARY OUTCOME: After septorhinoplasty operations; In the recovery unit, pain was evaluated by the anesthesiologist at 0 (t1), 2nd (t2), 6th (t3) and 24th (t4) hours using a visual analog scale [11] (0: no pain, 10: maximum)..[ First 24 hours after sphenopalatine ganglion injection] SECONDARY OUTCOME: After septorhinoplasty operations; In the recovery unit, nausea‐vomiting scale was evaluated by the anesthesiologist. .POBC (postoperative nausea and vomiting), Numeric Rank Score (NRS) for 24 hours following the end of the operation (0: No nausea, vomiting, 1: Nausea, no vomiting, 2: Vomiting once, 3: Two or more episodes of vomiting ) and three different periods (NRS1: 0–2 hours, NRS2: 2–6 hours, NRS3: 6–24 hours)[ First 24 hours after sphenopalatine ganglion injection] After septorhinoplasty operations; In the recovery unit, Postoperative analgesic requirement was evaluated by the anesthesiologist( at 0‐2 hours,2‐24 hours ve total)..[ First 24 hours after sphenopalatine ganglion injection ; ] After septorhinoplasty operations; In the recovery unit, presence of laryngospasm was evaluated by the anesthesiologist.[ First hours after sphenopalatine ganglion injection] INCLUSION CRITERIA: Patients aged 18‐50 who will undergo elective septorhinoplasty operations.
