Interventions/Control_1

Ultrasound-guided maxillary nerve block will be performed and 0.2% ropivacaine will be administered.
Consent will be obtained from the patients and their guardians on the day before surgery, and the groups will be randomly assigned. On the day of surgery, midazolam syrup 0.5 mg/kg will be administered 30 minutes before entering the operating room. After entering the operating room, general anesthesia will be induced. Maxillary nerve block with a local anesthetic (0.2% ropivacaine) at a dose of 0.15 mL/kg or local injection of saline at a dose of 0.15 mL/kg is performed according to the allocation on the previous day. As in conventional pain management methods, saline injection by the surgeon is performed immediately before the procedure. The amount of narcotic analgesics used intraoperatively and pain assessment immediately after awakening from anesthesia, at 2 hours, and at 4 hours will be performed. Postoperatively, the patient should be monitored for hypoxic events (SpO2<92%) and airway-related adverse events requiring tracheal intubation or ventilatory management. From the day after surgery onward, in addition to the usual postoperative rounds, pain assessment should be performed at 24 hours. The patient will be monitored for hypoxic events (SpO2<92%) and airway-related adverse events requiring intubation or ventilatory management until 24 hours after surgery.
