Kiesselbach's plexus

Kiesselbach's Plexus

Kiesselbach's plexus, also known as Little's area, is a region in the anterior part of the nasal septum where several arteries anastomose. This area is particularly prone to epistaxis, or nosebleeds, due to the rich vascular supply.

Anatomy

Kiesselbach's plexus is formed by the anastomosis of several arteries:

• Anterior ethmoidal artery
• Sphenopalatine artery
• Greater palatine artery
• Superior labial artery

These arteries converge in the anterior part of the nasal septum, creating a highly vascular region.

Clinical Significance

Due to the rich blood supply in Kiesselbach's plexus, it is a common site for nosebleeds. Epistaxis originating from this area can be anterior, meaning the bleeding comes from the front of the nose. Anterior nosebleeds are more common and usually easier to manage compared to posterior nosebleeds.

Management

Treatment for epistaxis from Kiesselbach's plexus typically involves:

• Direct pressure on the nose to control bleeding
• Application of vasoconstrictors to help constrict blood vessels
• Nasal packing to provide pressure and promote clotting

In cases where conservative measures are not effective, cauterization or surgical intervention may be necessary to stop the bleeding.
