What is Kiesselbach area?
The Kiesselbach plexus is a vascular network formed by five arteries that supply oxygenated blood to the nasal septum, which refers to the wall separating the right and left sides of the nose. This area is also commonly known as the Little’s area, Kiesselbach’s area, or Kiesselbach’s triangle.
What forms the Kiesselbach plexus?
Kiesselbach plexus is an anastomosis with branches from both the internal and external carotid artery systems. The anterior ethmoid, greater palatine, sphenopalatine, and superior labial arteries all form a plexus of vessels in the anteroinferior nasal septum.
Where is the Kiesselbach plexus?
nasal septum
Kiesselbach’s plexus is an integral anastomosis of five branches converging in the anterior inferior quadrant of the nasal septum (over the septal cartilage). The area has been referred to as Little’s Area, Kiesselbach’s Triangle or Kiesselbach’s Area.
What is the area of epistaxis?
Epistaxis (nosebleed) is one of the most common ear, nose, and throat (ENT) emergencies that present to the emergency room or primary care. There are two types of nosebleeds: anterior (more common), and posterior (less common, but more likely to require medical attention).
What are the arteries that Anastomose in the Kiesselbach area?
Little’s area (also known as Kiesselbach’s plexus) is found on the anterior nasal septum (Fig. 1) and is an anastomosis of 5 arteries: anterior ethmoidal artery, posterior ethmoidal artery, sphenopalatine artery, greater palatine artery, and the septal branch of the superior labial artery.
What is the pathophysiology of epistaxis?
Pathophysiology of Epistaxis Most nasal bleeding is anterior, originating from a plexus of vessels in the anteroinferior septum (Kiesselbach’s area). Less common but more serious are posterior nosebleeds, which originate in the posterior septum overlying the vomer bone, or laterally on the inferior or middle turbinate.
What is plexus anastomosing?
An anastomosis is the connection of two normally divergent structures. It refers to connections between blood vessels or between other tubular structures such as loops of intestine.
Why is Little’s area important?
It supplies the nasal septum. The arteries anastomose to form the plexus. It lies in the anterior inferior part of the septum known as Little’s area, Kiesselbach’s area, or Kiesselbach’s triangle. It is a common site for nosebleeds.
