Outcome Measures
Primary Outcomes (1)
time and amount of first postoperative rescue analgesia after two different blocks using Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) score
Postoperative pain will be recorded using Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) scores at admission to the PACU \[0\] minutes (baseline), \[30 \]minutes, \[1\], \[4\], \[8\],\[ 12\], \[18\] and \[24\] hours postoperatively. where the minimum score of zero (no pain) and the maximum score of 12 (the most severe pain). Children with the modified CHEOPS \[ ≥ 5 \]will be given supplemental analgesia with IV paracetamol 15 mg/kg , Pain scores will be recorded 15-20 minutes following the administration of this supplemental analgesia to assess pain relief. The number of children that required postoperative rescue analgesics, the first time to rescue analgesia, and the total amount of rescue analgesia consumed within \[24\] hours postoperatively will be recorded.

Interventions
After induction of general anaesthesia blockade of the contents of the pterygopalatine fossa is performed bilaterally before starting surgery as follows: After complete aseptic skin preparation and under ultrasound guidance images are obtained with a high-frequency linear array probe. The ultrasound transducer is placed in the infrazygomatic area, over the maxilla, angled \[45 \]degree cephalad. This probe position allows visualization of the pterygopalatine fossa,The needle is advanced using an out-of-plane approach, and the needle tip can usually be identified during movements. the injectate consisted of \[4\]mL of \[0.5% \]Bupivacaine combined with \[1\]mL of\[ 5\]µg dexmedetomidine. The injectate is delivered over \[15-20 \] seconds, while observing the spread of the local anesthetic under ultrasoundThe same procedure is then repeated on the contralateral side.
