Question 1 · Easy
An 8-year-old boy has repeated small nosebleeds from the right nostril, often after picking his nose. Blood pressure and platelet count are normal. The bleeding most likely arises from:
- AThe inferior turbinate mucosa
- BLittle's area on the anterior septum
- CWoodruff's plexus behind the turbinate
- DThe anterior ethmoidal artery high up
Show answerHide answer
Answer: B · Little's area on the anterior septum
Little's area on the anteroinferior nasal septum is the commonest site of epistaxis, especially in children and young adults. Here four arteries meet in Kiesselbach plexus: the anterior ethmoidal, the septal branch of the sphenopalatine, the greater palatine and the septal branch of the superior labial. The area is exposed to drying and finger trauma. Most bleeds stop with firm pinching of the soft nose while sitting up and leaning forward; recurrent bleeds can be cauterised.
- A: The turbinate mucosa is not a common bleeding site in children.
- C: Woodruff's plexus gives posterior bleeds in older, often hypertensive, adults.
- D: Anterior ethmoidal bleeds come from high in the nose, usually after trauma.
