The septum is a thin tissue in the middle of the nose separating the nose into two chambers.  It is made up of rigid bone towards the back and flexible cartilage towards the front of the nose.  It is lined by normal mucosa.  There are a number of causes of abnormal function of the nasal septum and diseases.  The most common is a septal deviation (this will be addressed in a later blog).  Tumours may involve the septum and may be benign e.g. papilloma’s or malignant e.g. squamous carcinoma.  Trauma can also affect the nose which may be direct, for instance, a rugby injury or indirect with inhalation of industrial fumes or cocaine.  Infections can also occur e.g. Tuberculosis.  Autoimmune disease can involve the nasal septum, for instance, sarcoid.  These diseases can result in swelling, destruction, perforation, and nose bleeds.
