Severe Delayed Hemorrhage After Cosmetic Rhinoplasty in the Setting of Maxillary Vascular Malformation.

Late epistaxis after rhinoplasty is a rare but potentially life-threatening occurrence. This case report concerns a 20-year-old woman who had severe epistaxis 5 and 10 days after a closed rhinoplasty with internal osteotomies and who ultimately required transcatheter arterial embolization for definitive control of the hemorrhagic source. Arterial hypervascularity, with signs of arteriovenous malformation, of the midface at the level of the piriform aperture and maxilla was seen on angiography.
