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

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.

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.
