Summary

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.

  • Infraorbital Nerve Block

Interventions

PROCEDURE

Bilateral Sphenopalatine Ganglion Block

A bilateral sphenopalatine ganglion block will be performed after induction of general anesthesia using 4 mL of 0.5% bupivacaine. The local anesthetic will be applied intranasally with a cotton-tipped applicator placed parallel to the zygomatic arch and advanced to the posterior nasal cavity. The applicator will remain in place for 15 minutes.

PROCEDURE

Bilateral Infraorbital Nerve Block

A bilateral infraorbital nerve block will be performed after induction of general anesthesia using 4 mL of 0.5% bupivacaine per side. The block will be guided by linear ultrasound to identify the infraorbital foramen and administered with a 22G needle around the nerve. A 15-minute absorption period will be allowed before the surgical procedure begins.
