Final Answer:
Kiesselbach's plexus, also known as Little's area, refers to a region in the anterior part of the nasal septum.
Step-by-step explanation:
This area is a vascular network formed by the anastomosis of several arteries, including the anterior ethmoidal artery, posterior ethmoidal artery, and septal branch of the superior labial artery. Kiesselbach's plexus is a common site for nosebleeds (epistaxis) due to its rich vascular supply, and it is often implicated in cases of anterior nosebleeds.
Kiesselbach's plexus, or Little's area, is a vascular network located in the anterior portion of the nasal septum. This plexus is formed by the anastomosis of several arteries, including the anterior ethmoidal artery, posterior ethmoidal artery, and septal branch of the superior labial artery. Due to its rich vascular supply, Kiesselbach's plexus is a common site for nosebleeds, known as epistaxis.
The fragility of the blood vessels in this region, coupled with factors like dry air, trauma, or inflammation, can lead to the rupture of blood vessels, resulting in bleeding. Clinically, epistaxis originating from Kiesselbach's plexus is often anterior nosebleeds, as opposed to posterior nosebleeds that involve arteries deeper in the nasal cavity. Understanding the anatomy of Kiesselbach's plexus is crucial for managing and treating anterior nosebleeds effectively.
