What is the name of the condition where the nasal septum is deviated?

The condition where the nasal septum is deviated is known as a deviated septum. This occurs when the thin wall between the nasal passages, which is called the septum, is displaced to one side, resulting in one nasal passage being smaller than the other. This can lead to various symptoms, including nasal obstruction and difficulty breathing through the nose. A deviated septum may be congenital or result from injury or trauma to the nose.

Other options, while related to nasal issues, do not describe the deviation of the septum directly. Septal perforation refers to a hole in the septum, which can cause complications but is distinct from mere deviation. Nasal obstruction is a broader term that can arise from various causes, including a deviated septum, but does not specifically identify the condition itself. Sinusitis is an inflammation of the sinuses, often resulting from infections, allergies, or other factors, and is separate from the structural issue of a deviated septum.
