A deviated septum is when the bone and cartilage that divides the inside of the nose in half is uneven. The most common symptom from a badly deviated or crooked septum is difficulty breathing through the nose, which is usually worse on one side. In some cases, a crooked septum can interfere with sinus drainage and cause repeated sinus infections. Septoplasty is the preferred surgical treatment to correct a severely deviated septum.
