Severe late-onset epistaxis following Le Fort I osteotomy: angiographic localization and embolization

Epistaxis following maxillofacial trauma or maxillofacial surgery is uncommon. It usually occurs within 24 hours of the injury and can usually be controlled by packing. Rarely internal maxillary artery ligation is necessary and embolization has been used in some cases of severe trauma. We present a case of severe late-onset epistaxis following Le Fort I osteotomy. The diagnostic approach and treatment are discussed.
