What is undulation of the nasal septum?

Undulation of the nasal septum refers to the presence of a wavy or irregular curvature in the nasal septum, which is the thin wall of cartilage and bone that separates the nasal cavity into two nostrils. This deviation can be mild, moderate, or severe and may cause various symptoms, such as nasal obstruction, difficulty breathing, recurrent sinus infections, and chronic headaches. Undulation of the nasal septum can be congenital, meaning that it is present from birth, or it can be acquired due to trauma, injury, or certain medical conditions. Treatment for septal deviation may involve conservative management with nasal sprays or medications to reduce inflammation, or surgical correction known as septoplasty to straighten and reshape the nasal septum, improving airflow and alleviating symptoms.
