About Septoplasty
The nasal septum is the vertical wall of cartilage that divides your nasal cavity into left and right passages. The front part of the septum is composed of flexible cartilage that helps support the tip and bridge of the nose. The back and upper portions of the septum consist of thin bone, providing a firm foundation that keeps the nasal passages stable, open, and properly supported. A septum does not have to be perfectly centered. In fact, mild deviation is extremely common and may cause no symptoms. However, a more significant bend can narrow one or both of the nasal passages and block airflow. (1) A patient’s individual degree of visible asymmetry does not necessarily display how much breathing difficulty they have. Rather, what matters most is whether the deviation is actively obstructing the airway.
Septoplasty is primarily a functional procedure, not one designed to reshape the nose cosmetically. Although medications like decongestants, antihistamines, or nasal steroid sprays can reduce congestion and swelling around the septum, they cannot physically straighten deviated bone or cartilage. If persistent blockage stems from the septum itself, septoplasty directly targets that underlying structural issue. (2)
What Causes a Deviated Septum?
You may be born with a deviated septum or develop one as the nose grows, sometimes worsening with age. Some people develop a deviation after experiencing trauma or an injury to the nose, such as a broken nose, sports injury, car accident, or other facial injury. (3) The amount of deviation varies from person to person. In fact, a previous injury does not have to be severe or recent for an individual to have structural damage later. Many people with mild deviated septa do not seek treatment. Instead, treatment matters more when the structural asymmetry causes persistent symptoms or interferes with airflow.
