Where do the majority of epistaxis episodes occur?

• A. Superior nasal conchus
• B. Kiesselbach's plexus
• C. Sphenoethmoidal recess
• D. Superior nasal meatus

Answer: (B)

The majority of epistaxis episodes occur at Kiesselbach's plexus, which is a vascular plexus located in the anterior part of the nasal septum. This area is particularly prone to bleeding due to its rich blood supply consisting of contributions from several arteries, including the anterior ethmoidal artery, sphenopalatine artery, greater palatine artery, and the septal branch of the superior labial artery. When the mucosa in this region becomes dry, irritated, or otherwise compromised, the fragile vessels can easily rupture, leading to nasal bleeding. This makes Kiesselbach's plexus a common site for both anterior epistaxis, often seen in children and young adults, as well as in other populations when conditions like nasal trauma or frequent nose-picking occur. The other areas mentioned, such as the superior nasal concha, sphenoethmoidal recess, and superior nasal meatus, are less commonly associated with epistaxis. They do not have the same density of blood vessels near the surface, which reduces the likelihood of bleeding compared to Kiesselbach's plexus. Thus, the prevalence of epistaxis in Kiesselbach's plexus is well established in clinical practice.
