Background and Aims Cleft lip and palate (CL/P) are common congenital craniofacial anomalies resulting from a failed fusion of the palate and lip during embryonic development. Bilateral suprazygomatic maxillary nerve blocks provide effective postoperative pain relief for palate surgery.

Methods Pediatric patients with congenital CL/P underwent cheiloplasty with ultrasound-guided suprazygomatic maxillary nerve block. These patients are at considerable risk for postoperative airway obstruction and respiratory failure, often necessitating high opioid doses, which can increase these complications. The bilateral suprazygomatic maxillary nerve block significantly reduced intraoperative opioid requirements and postoperative pain scores, minimizing complications.

Conclusions With a Very Low Technical Failure Maxillary Nerve Blocks is a promising Technique pos operative Pain Relief after Cleft Palate Repair in Children.Ultrasound-guided suprazygomatic maxillary nerve block is an easy and efficient technique to assess needle and LA spread location. Ultrasound imaging allows good visualization of the anatomical structures of the pterygopalatine fossa in 90% of cases and permits to clearly verify the final location of the LA solution in 94% of the blocks. The postoperative pain management was optimal with low pain scores and low consumption of nalbuphine. 80% of patients did not require continuous opioid infusion.
