Septoplasty is used to straighten or correct the deviation of a nasal septum, the partition that runs between the two nasal cavities. If the septum is too narrow or deviates it can constrict airflow and lead to sinus problems, causing in turn snoring during your sleep. Septoplasty is performed by raising the lining off both sides of the nasal septum through an incision inside the nose. Septoplasties are performed through the nose without any scars on the outside of the nose or face. An incision is made on the inside of the nose. The septum is then straightened by removing or reshaping the cartilage and bone and a plastic splint is temporarily placed to support the septum.
