The nasal septum is the piece of cartilage and bone that separates the two sides of the nasal cavity. The turbinates are little bones that project from the sides of the nasal cavity and are covered with mucosa to warm and moisturized the airflow through the nose. At times the nasal septum may be deviated, thus causing nasal obstruction, nasal pain, recurrent sinusitis and/or recurrent nosebleeds. In addition, the turbinates may be enlarged, thus further contributing to nasal congestion.
A deviated nasal septum may be the result of trauma to the nose or may occur from birth. It is not necessary to fracture the bridge of the nose to cause severe deviation of the septum. Often minor trauma to the nose can result in a fracture of the nasal septum. The septum may be deflected to one side or twisted with obstruction of both sides. In addition, a spur of bone may project into the nasal cavity or into a sinus opening. Enlargement of the turbinates is an anatomic variation with no particular cause. Frequently, the turbinates will be enlarged on the side opposite the septal deviation.
Septal Spur: These are sharp angulations seen in the nasal septum occuring at the junction of the vomer below, with the septal cartilage and / or ethmoid bone above. This type of deformity is the result of vertical compression forces. Fractures that occur through nasal septum during injury to the nose may also produce sharp angulations . These fractures heal by fibrosis that extend to the adjacent mucoperichondrium. This increases the difficulty of flap elevation in this area.
