Septoplasty straightens a deviated (crooked) septum. The septum separates the right and left sides of your nose. It’s made of cartilage and bone and lined with a thin mucous membrane.
A normal septum is straight and centered. A deviated septum is bent or off-center. The deviation can happen:
- During development before birth
- As your nose grows
- After an injury
A deviated septum can cause a range of problems. A bent septum can disturb your sleep and breathing, and in some cases may lead to sinus infections and headaches.
