Posterior epistaxis occurs from which of the following?
Posterior epistaxis occurs from which of the following?
Show Hint
Posterior bleed = Woodruff's plexus; anterior bleed = Little's area/Kiesselbach.
Updated On: Jun 24, 2026
- Woodruff's plexus
- Kiesselbach's plexus
- Atherosclerosis
- Little's area
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Split nosebleeds into front and back. The key is to match the named vascular landmark to the correct location.
Step 2: The back of the nose drains through a venous network on the lateral wall near the posterior end of the inferior turbinate. This is Woodruff's plexus, the classic source of posterior epistaxis, typically seen in older hypertensive patients with brisk bleeds.
Step 3: The front of the nose has Little's area on the antero-inferior septum, where Kiesselbach's plexus sits. Both of these belong to anterior epistaxis, so the options naming Kiesselbach's plexus and Little's area are excluded.
Step 4: Atherosclerosis is a vessel-wall disease, not a defined bleeding point in the nose, so it cannot be the answer.
\[\boxed{\text{Woodruff's plexus}}\]
