A nosebleed (epistaxis) usually occurs in the anterior part of the nose from an area known as Kiesselbach's plexus which consists of arteries. Woodruff's plexus is a venous plexus in the posterior part and a nosebleed here accounts for only between 5 and 10 per cent of nosebleeds. Older adults are most often affected. [5]
One of the most common medical conditions involving the nose is a nosebleed (epistaxis). Most nosebleeds occur in Kiesselbach's plexus, a vascular plexus in the lower front part of the septum involving the convergence of four arteries. A smaller proportion of nosebleeds that tend to be nontraumatic occur in Woodruff's plexus.

The exact mechanism for the formation of hematoma from nasal trauma is controversial, but thought to occur in nasal septal hematomas when there is forced to the nasal cartilage. The force causes the perichondrial blood vessels to leak and rupture in the nasal septum. [7] The cartilage in the septum is avascular and can be 2–4 mm thick.
