Which epistaxis is more commonly associated with Kiesselbach's plexus?

Kiesselbach's plexus, also known as Little's area, is a network of small blood vessels located in the anterior part of the nasal septum. This region is particularly vulnerable to bleeding because of its rich vascular supply and proximity to the nasal mucosa.

Anterior epistaxis, which occurs when bleeding originates from the front portion of the nose, is most commonly associated with Kiesselbach's plexus. The bleeding in this type stems from the superficial vessels found in this area, making it a frequent site for nosebleeds, especially in children and young adults. Factors such as dry air, nasal trauma, or irritation can easily disrupt the mucosa here, leading to anterior nosebleeds.

In contrast, posterior epistaxis generally occurs from larger vessels located deeper in the nasal cavity, often in the sphenopalatine artery region. Septal epistaxis can involve bleeding from the septal wall but does not specifically refer to Kiesselbach's plexus. Traumatic epistaxis can occur in various locations depending on the nature and site of the trauma, not specifically tied to Kiesselbach's plexus. Thus, anterior epistaxis stands out as the type most directly linked to this vascular network.
