Internal maxillary artery (IMA) pseudoaneurysms are rare, and typically occur following trauma or orthognathic surgery. Pseudoaneurysms are life-threatening conditions, and expeditious workup and treatment is critical. Endoscopic treatment of an IMA pseudoaneurysm is a feasible option and should be considered when IR embolization is not available. The objective of this study is to review the literature on IMA pseudoaneurysms and present the first reported case of an IMA pseudoaneurysm successfully treated endoscopically.
