Posttraumatic pseudoaneurysms of the sphenopalatine artery are rare. Only a few cases have been reported. We report two cases of hemorrhage due to pseudoaneurysm of the sphenopalatine artery. The hemorrhage was uncontrollable. It required embolization. Two patients visited our hospital for treatment of zygomaticomaxillary complex fracture. At the emergency room, patients presented with massive nasal bleeding which ceased shortly. After reduction of the fracture, patients presented persistent nasopharyngeal bleeding. Under suspicion of intracranial vessel injury, we performed angiography. Angiograms revealed pseudoaneurysms of the sphenopalatine artery. Endovascular embolization was performed, leading to successful hemostasis in both patients. Due to close proximity to pterygoid plates, zygomaticomaxillary complex fracture involving pterygoid plates may cause injury of the sphenopalatine artery. The only presentation of sphenopalatine artery injury is nasopharyngeal bleeding which is common. Based on our clinical experience, although pseudoaneurysm of maxillary artery branch after maxillofacial trauma has a low incidence, suspicion of injury involving deeply located arteries and early imaging via angiogram are recommended to manage recurrent bleeding after facial trauma or surgery.
