5. Venous drainage
A rich submucosal venous plexus, deep to the nasal
mucosa, provides venous drainage of the nose
Sphenopalatine vein
Facial vein
Ophthalmic vein
Veins in the nose essentially follow the arterial pattern

6. Anastomosis Kiesselbach’s Plexus (Little’s Area)
This area is in the anterior septum where the capillaries merge. It is often the site of anterior epistaxis.
LEGS: Labial (superior), Ethmoidal , Greater palatine, and Sphenopalatine arteries.

7. Woodruff ’s Plexus
Anastomosis
Woodruff plexus, known as naso-nasopharyngeal plexus, is located at the posterior
1 cm of the nasal floor, inferior meatus, and middle meatus.
Initially thought to be an arterial plexus but recent studies suggest
it a venous plexus
Most common site for posterior epistaxis
