Where is Littles area

Little’s 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 Little's area?

Blood supply of nose Little’s Area Little’s area is situated in the anterior inferior part of nasal septum just above the vestibule. This vascular area is most common site of nose bleed in children and young adults. 4 arteries anastomose here to form a plexus known as the Kiesselbach’s plexus.

Where do most nosebleeds originate?

More than 90% of bleeds occur anteriorly and arise from Little’s area, where the Kiesselbach plexus forms on the septum. The Kiesselbach plexus is where vessels from both the ICA (anterior and posterior ethmoidal arteries) and the ECA (sphenopalatine and branches of the internal maxillary arteries) converge.

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).

Which artery is responsible for epistaxis?

This vascular network of vessels is a confluence of three terminal arteries: sphenopalatine artery (SPA), anterior ethmoid artery (AEA), and facial artery (FA: via the superior labial artery) and accounts for 90–95% of epistaxis [1].

How is Little's area formed?

Kiesselbach’s plexus is a vascular network of four or five arteries in the nose. 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.

What is anterior and posterior epistaxis?

Most cases of epistaxis occur in the anterior part of the nose, with the bleeding usually arising from the rich arterial anastomoses of the nasal septum (Kiesselbach’s plexus). Posterior epistaxis generally arises from the posterior nasal cavity via branches of the sphenopalatine arteries.

What are the three types of epistaxis?

Epistaxis can be divided into 2 categories, anterior bleeds and posterior bleeds, on the basis of the site where the bleeding originates (see the image below). Posterior epistaxis from the left sphenopalatine artery.

Which artery is ligated in anterior epistaxis?

In 1948, Silverblatt first described the ligation of the anterior ethmoid artery. These techniques are still utilized around the world to manage patients with refractory epistaxis.

How do you cauterize a small area?

If you can see a bleeding point around Little’s area, direct digital pressure on the lower nose for at least five minutes. It is possible to cauterise a bleeding point directly with a silver nitrate stick if you can see the vessel. Use a Thudichum speculum to lift and separate the external nares to view Little’s area.

What arteries form 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 paranasal sinus?

How can you tell the difference between anterior and posterior nosebleeds?

Anterior nosebleeds originate toward the front of the nose and cause blood to flow out through the nostrils. This is the most common type of nosebleed and it is usually not serious. Posterior nosebleeds originate toward the back of the nasal passage, near the throat.

What is another name for nose bleeding?

Nosebleeds (medical term is “epistaxis“) are very common. Almost every person has had at least one in their lifetime. They are usually caused by dry air or nose-picking.
