Abstract
The nose has a robust blood supply derived from both internal and external carotid arteries. The main blood supply of the nasal tip and skin is derived primarily from the lateral nasal arteries, with a variable contribution from the columellar arteries. We present a patient with cut nose resulting from a homicidal attack in which the lower two-thirds of the nose was severed starting at the bony–cartilaginous junction of the dorsum of the nose down to the tip of the nose. The skin–cartilage flap was attached only to the columella and to the caudalmost 3 mm of the left ala nasi. The detached skin–cartilage flap was replaced and sutured anatomically, and the flap completely survived in spite of cutting of both lateral and dorsal nasal arteries.
