Woodruff's plexus was discovered by George H. Woodruff in 1949. The plexus is located below the posterior end of the inferior concha, on the lateral wall of the nasal cavity.[1][2][3] He described it as the naso-nasopharyngeal plexus.[1]
Structure
Woodruff's plexus is located on the lateral wall of the nasal cavity below the posterior end of the inferior nasal concha (turbinate).[3] The plexus is of large thin-walled veins which lie in a thin mucosa.[4]
Clinical significance
Bleeding
A nosebleed (epistaxis) usually occurs in the anterior part of the nose from an area known as Kiesselbach's plexus which consists of arteries. Woodruff's plexus is a venous plexus in the posterior part and a nosebleed here accounts for only between 5 and 10 per cent of nosebleeds. Older adults are most often affected.[5]

Treatment
Posterior nasal packing is needed for posterior epistaxis.
