Official title
Effect of Bilateral Maxillary Block on Intraoperative Remifentanil Consumption in Septorhinoplasty Surgery
Overview
The maxillary nerve block is a regional anesthetic technique targeting the sensory distribution of the maxillary nerve and is particularly preferred to provide analgesia in midfacial and maxillary surgical procedures. It has been used to optimize perioperative and postoperative pain control, reduce intraoperative opioid requirements, and support hemodynamic stability in procedures including septorhinoplasty, nasal bone osteotomies, nasal valve surgery, and endoscopic sinus surgery. This study aimed to compare the effects of the timing of bilateral maxillary nerve block administration (post-intubation vs. pre-extubation) on intraoperative remifentanil consumption and postoperative analgesia in patients undergoing septorhinoplasty.
Interventions
- Drug Preoperative Maxillary Block
After the intubation, the block procedure will be performed under ultrasound guidance using an infrazygomatic approach to access the pterygopalatine fossa. Prior to the procedure, the cheek region will be prepared in accordance with aseptic conditions. A linear ultrasound probe will be positioned over the infrazygomatic area to visualize the maxillary tuberosity, lateral pterygoid plate, coronoid process, and mandibular condyle. The following image optimization using the jaw-opening maneuver, th - Drug Postoperative Maxillary Block
At the end of the surgery, before the extubation, the block procedure will be performed under ultrasound guidance using an infrazygomatic approach to access the pterygopalatine fossa. Prior to the procedure, the cheek region will be prepared in accordance with aseptic conditions. A linear ultrasound probe will be positioned over the infrazygomatic area to visualize the maxillary tuberosity, lateral pterygoid plate, coronoid process, and mandibular condyle.
