ABSTRACT

Background: Paramaxillary transoral endoscopic approach to the infratemporal fossa and maxillary artery is an excellent alternative to endoscopic transantral or transnasal transmaxillary approach to the maxillary artery. Preoperative vascular imaging of the maxillary artery should clearly delineate if the artery runs medial or lateral to the inferior belly of the lateral pterygoid muscle. The paramaxillary corridor, the space created between de periosteum and the posterior wall of the maxilla, leads directly to the infratemporal fossa and pterigomaxillary fissure. Transoral ligation of the maxillary artery is an excellent alternative to embolization in selected cases of juvenile nasopharyngeal angiofibromas when properly selected.
Objetive: To report the results obtained using this surgical technique of minimal invasion.
Material and Method: A retrospective multicenter analysis, done from August 2013 to January 2016, including a private reference clinic of Otorhinolaryngology in Veracruz, Mexico, and two regional hospitals of reference in Monterrey, Nuevo Leon, and in Mexico City.
Results: There were included 22 cases treated via paramaxillary corridor in the study period, from which in 15 (68.2%) maxillary artery was cauterized or ligated via transoral before than endonasal tumoral resection.
Conclusions: This technique represents an excellent alternative to the endoscopic transantral or transnasal transmaxillary approach to the maxillary artery, as long as the surgeon has knowledge and comprehension of the anatomy of the region and its possible variants.
