Article Abstract
Background: Sagittal split ramus osteotomy is often associated with significant postoperative pain. Intraoral inferior alveolar nerve blocks have variable success rates and higher risks of vascular complications, while ultrasound-guided approaches to the pterygomandibular space require precise needle placement in a narrow anatomical space. We present a novel perioperative application of ultrasound-guided lateral pterygoid muscle injection for regional anesthesia.
Case Presentations: Three female patients underwent bilateral sagittal split ramus osteotomy under general anesthesia. After anesthesia induction, ultrasound-guided lateral pterygoid muscle injections were performed using 10 mL of 0.25% levobupivacaine. All patients demonstrated excellent postoperative pain control (numerical rating scale score ≤ 2) with minimal analgesic requirements and no complications.
Conclusion: This novel lateral pterygoid muscle injection technique for perioperative analgesia demonstrates promising clinical efficacy through a simplified ultrasound-guided approach, providing effective opioid-free postoperative pain management for sagittal split ramus osteotomy.

Objective: Sacrifice of pterygopalatine fossa (PPF) neurovascular structures during endoscopic endonasal transpterygoid approach (EETPA) may impact a patient's comorbidity. We present anatomical and surgical techniques for maximizing PPF transposition while preserving its neurovascular structures through orbito-pterygo-sphenoidal (OPS) ligament release and descending palatine canal (DPC) decompression.
Methods: The EETPA was performed on six specimens.

: The varied shape and size of the sphenoid sinuses result in a highly variable degree of extension, described in different ways in the literature. The aim of the study was to create the authors' classification of the sphenoid sinus extensions into the sphenoid bone processes. : The study was retrospective, based on the results of head CT scans.

Objectives: Various studies have described anatomical variations of the auriculotemporal nerve (ATN), starting with its initial nerve roots and relationship to the middle meningeal artery (MMA). Despite its crucial role in innervating various regions, the precise anatomical course of ATN and its variants remains uncertain. This study aims to provide a comprehensive review of the ATN, including its anatomical course, variations, and clinical significance, particularly in relation to head and neck surgery.

Objective: To show our experience in performing endoscopic-assisted maxillectomy (EAM), with the aim of facilitating delineation of tumour resection and improve the achievement of free tumour resection margins.
Methods: Patients undergoing EAM between 2021 and 2024 were reviewed. During the endoscopic approach, the medial and lateral plates of the pterygoid were drilled, taking as reference the superior margin of the inferior turbinate.

: Variations in the course of the maxillary artery (MA) relative to the lateral pterygoid muscle (LPM) pose critical challenges in surgical, anesthetic, and interventional procedures involving the infratemporal fossa (ITF). These variations can increase the risk of hemorrhage, nerve injury, or incomplete anesthesia. The present study aimed to elucidate the topographic relationship between the MA and LPM by combining high-resolution radiological imaging with a comprehensive analysis of anatomical literature.
