Diseases of the nasal septum (鼻中膈疾病) - Septal haematoma (鼻中膈血腫)

Septal haematoma (鼻中膈血腫)
A collection of blood beneath the mucoperichondrium and posteriorly the mucoperiosteum of the nasal septum.


Aetiology:
Usually complicates nasal trauma, either accidental or iatrogenic following septal surgery. Rarely a spontaneous haematoma can occur in a bleeding diathesis.

Clinical features:
Presents as nasal obstruction with widening of the septum on inspection.

Management:
In the acute stage, treat by incision and drainage, however, after 48hrs, organization of haematoma occurs and evacuation of the clot is difficult. Antibiotics are given to prevent secondary infection.
