[Septal hematoma: Report of two pediatric cases].

Hematomas and septal abscesses are an emergency in rhinology and require early surgical treatment due to the risk of infectious, functional, and aesthetic complications. They generally occur as a consequence of nasal trauma, although they have also been described in relation to other triggers. Accumulation of blood or pus between the mucoperichondrium and septal cartilage, causes avascular necrosis injury to the cartilage with cartilage destruction.
