Management of pseudoaneurysms of the internal maxillary artery derived from orthognathic surgery based on one case

ConclusionPseudoaneurysms derived from external carotid artery branches must be suspected when patients show multiple episodes of bleeding (epistaxis or through the surgical approach) within the first two weeks after orthognathic surgery. If so, vascular CT or angiography should be performed to rule out the presence of vascular injuries. In case a pseudoaneurysm is identified, vascular embolization with N-butyl-cyanoacrylate seems to be the best treatment if available. If this treatment is not available or bleeding cannot be controlled, surgical ligature of the injured vessel is a valid treatment.
