Transnasal Sphenopalatine Ganglion Block for Postoperative Pain and Recovery in Tonsillectomy (TONwoPA)

The aim of this clinical trial is to evaluate the effectiveness of transnasal transmucosal sphenopalatine ganglion block in reducing post-tonsillectomy pain. The study also investigates its impact on rescue analgesic requirements and postoperative recovery by comparing 5% lidocaine with placebo. Participants will receive a transnasal transmucosal sphenopalatine ganglion block with either 5% lidocaine or placebo (saline). Postoperative pain levels and opioid consumption will be monitored during the first 24 hours after surgery. In addition, length of hospital stay, the occurrence of primary and secondary post-tonsillectomy hemorrhage up to 14 days, unplanned hospital readmissions after discharge, and patient satisfaction on postoperative day 14 will be assessed.

Effect of Bilateral SPG and Infraorbital Nerve Blocks on Recovery After Septorhinoplasty

This prospective, randomized, double-blind controlled study aims to compare the effects of bilateral sphenopalatine ganglion and infraorbital nerve blocks on postoperative recovery quality in patients undergoing elective septorhinoplasty under general anesthesia. A total of 90 adult patients (aged 18-65, ASA I-II) will be randomly assigned into two groups: Group 1 will receive bilateral sphenopalatine ganglion block, and Group 2 will receive bilateral infraorbital nerve block. Both blocks will be performed using 4 mL of 0.5% bupivacaine. The primary outcome is the quality of recovery assessed 24 hours after surgery using the QoR-15 questionnaire. Secondary outcomes include intraoperative anesthetic consumption (propofol, remifentanil), emergence agitation (RASS scale), postoperative pain (VAS), need for rescue analgesics (morphine), postoperative nausea and vomiting (VDS), antiemetic consumption (ondansetron), facial edema and hematoma, and length of stay in the post-anesthesia care unit (PACU). All procedures will follow standardized general anesthesia protocols. The study aims to determine which block technique provides superior postoperative recovery, better pain control, fewer side effects, and higher patient satisfaction. No placebo will be used, and no biological samples will be collected.

Sphenopalatine Ganglion Block in Bimaxillary Orthognathic Surgery

The goal of this clinical trial is to evaluate whether sphenopalatine ganglion (SPG) block helps with intraoperative pain control, reduces postoperative edema, and decreases pain in adults aged 18 to 45 undergoing bimaxillary orthognathic surgery. The main questions it aims to answer are: * Does SPG block help decrease postoperative swelling and pain compared to a sham block? * Does it improve pain control during surgery and reduce opioid use? Researchers will compare patients receiving SPG block to those receiving a sham block to determine if this technique provides better pain relief and reduces postoperative complications. Participants will: * Be 18 to 45 years old and undergo bimaxillary orthognathic surgery. * Be randomly assigned to receive either a SPG block or a sham block before surgery. * Be monitored for 1 month after surgery to assess pain levels, swelling, opioid use, and possible complications.
