Comparative Study of Bilateral Greater Palatine Nerve Block and Bilateral Suprazygomatic Maxillary Nerve Block for Intraoperative Analgesia in Children Undergoing Palatoplasty

Background: Regional anesthesia in pediatrics is recommended especially in congenital Cleft Palate (CP). Greater Palatine Nerve block (GPN) and Suprazygomatic Maxillary Nerve block (SMN) are methods for regional block in CP.Patients and Methods: Forty pediatric patients were divided into 2 groups: 20 patients received bilateral greater palatine nerve block and 20 patients received bilateral suprazygomatic nerve block. All regional block were received after general anesthesia. Intraoperative hemodynamics, number of fentanyl doses and complications were recorded.Results: There were no significant differences between both groups in demographic data, hemodynamic parameters, intraoperative complications. Intraoperative analgesic requirements were significantly less in GPN group than SMN group.Conclusion: Bilateral GPN block in children undergoing palatoplasty was accompanied by superior levels of intraoperative analgesia as compared to the use of bilateral SMN block in the same population.
