Kiesselbach's plexus
The bones and cartilage of the nasal septum-- viewed from right side. Kiesselbach's plexus (not labelled) is the anterior part of the nasal septum where several arteries anastomose.
Kiesselbach's plexus, which lies in Kiesselbach's area, Kiesselbach's triangle, or Little's area, is a region in the anteroinferior part of the nasal septum where five arteries anastomose to form a vascular plexus of that name. The arteries are:[1]
- Anterior ethmoidal artery (from the ophthalmic artery)
- Posterior ethmoidal artery (from the ophthalmic artery)
- Sphenopalatine artery (terminal branch of the maxillary artery)
- Greater palatine artery (from the maxillary artery)
- Septal branch of the superior labial artery (from the facial artery)
Significance
Ninety percent of nose bleeds (epistaxis) occur in Little's area, as it is exposed to the drying effect of inspiratory current.[2][3]
History
Kiesselbach's plexus is named after Wilhelm Kiesselbach (1839–1902) a German otolaryngologist. James L. Little an American surgeon, first described the area in 1879, Kiesselbach published his paper in 1884. Little described the area as being "about half an inch .... from the lower edge of the middle of the column [septum]." [4]
