Endoscopic paramaxillary ligation of the internal maxillary artery.

Endoscopic skull base surgery is increasingly utilized for managing skull base tumors. Complex techniques for resecting multicompartmental lesions can lead to higher intraoperative bleeding rates. While embolization can reduce blood flow, it may not always be feasible and can introduce additional risks. Endoscopic techniques allow for direct visualization and coagulation of parent arteries. This study discusses a subperiosteal transoral medial dissection technique, endoscopic paramaxillary corridor, to enable early vascular control prior to resection.
