<unk>  is a condition affecting the<unk>  septum. It can be associated with trauma. A septal<unk>  is blood that collects in the space between the septal cartilage and the overlying perichondrium (a cross section of the cartilaginous portion of the<unk>  septum). A<unk>  may deprive the septal cartilage of its blood supply from the overlying mucosa and can lead to permanent sequelae. The septal cartilage has no blood supply of its own and will receives all of its nutrients and oxygen from the perichondrium. An untreated septal<unk>  may lead to the destruction of the septum and immediate drainage is necessary. Timely diagnosis and/or treatment of septal<unk> s can cause what is called a saddle nose deformity. This condition is more common in children because the septum is thicker and the lining more flexible.
