Kiesselbach's plexus

Kiesselbach's plexus, is a vascular network of the four arteries that supply the nasal septum. The arteries anastomose to form the plexus which is a common site for nosebleeds. It lies in the anterior inferior part of the septum known as Little's area, also Kiesselbach's area, or Kiesselbach's triangle. The arteries are:[1]

The bones and cartilage of the nasal septum-- viewed from right side. Kiesselbach's plexus (not labelled) is in the anterior inferior part of the nasal septum known as Little's area, where several arteries anastomose.

It runs vertically downwards just behind the columella, crosses the floor of the nose and joins venous plexus on the lateral nasal wall. It is a common site for bleeding in young people.[2]

Clinical significance

Ninety percent of nosebleeds (epistaxis) occur in Kiesselbach's plexus, as it is exposed to the drying effect of inspiratory currents and to finger nail trauma and is the usual site for nosebleeds in children and young adults.[3][4]


James Lawrence Little (1836–1885), an American surgeon, first described the area in detail in 1879. Little described the area as being "about half an inch ... from the lower edge of the middle of the column [septum]".[5]

Kiesselbach's plexus is named after Wilhelm Kiesselbach (1839–1902), a German otolaryngologist who published a paper on the area in 1884.
