Result from bleeding within the superichondrial plane of the septum
Etiology : Trauma, Bleeding disorders
Treatment : Early surgical drainage by giving a horizontal incision at septal base and a tight intranasal packing to prevent reaccumulation.

Infection can occur in the hematoma leading to abscess formation.
