Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.

Prevention
Comparator / control treatment
In the control group (Group C, n=40), 2 mL of 0.9% NaCl solution was applied into both SPG areas. 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. 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.

Summary
Brief summary
The primary aim of our study was to test the hypothesis that SPG blockade provides more analgesia in the first 24 hours postoperatively than the control group in septorhinoplasty operations. In addition, the secondary aim of our study was to investigate the effects of SPG blockade on the ability to further reduce nausea-vomiting, sore throat, and laryngospasm.
