Sphenopalatine ganglion block using bupivacaine + dexamethasone: Patients will receive sphenopalatine ganglion block (SPGB) using 4 mL of 0.25% bupivacaine combined with 1 mL of dexamethasone.
General anesthesia: Patients will receive general anesthesia alone.
Study summary
This study aims to evaluate the efficacy of ultrasound guided sphenopalatine ganglion block (SPGB) through the suprazygomatic approach in optimizing the quality of surgical field as well as its effect on postoperative pain relief in patients undergoing transsphenoidal pituitary surgeries under general anesthesia.

Primary outcome measure(s)
Quality of surgical field visibility — Intraoperatively Quality of surgical field visibility will be measured at the beginning of surgery and at 30 mins interval through a pre-defined average category scale (ACS) (from 0 to 5). The ideal category scale values for surgical conditions were pre-determined to be ≤3.
0=No bleeding
1. Slight bleeding - no suctioning of blood required
2. Slight bleeding - occasional suctioning required. Surgical field not threatened
3. Slight bleeding - frequent suctioning required. Bleeding threatens surgical field a few seconds after suction is removed
4. Moderate bleeding - frequent suctioning required. Bleeding threatens surgical field directly after suction is removed
5. Severe bleeding - constant suctioning required. Bleeding appears faster than can be removed by suction. Surgical field severely threatened and surgery not possible
