Crooked nasal septum can severely impede breathing and the cleansing and warming of the inhaled air. In people with a crooked nasal septum, the cartilaginous sheet runs obliquely or takes on an S-shape, resulting in impaired nasal passage. Nasal obstruction affects the difficulty in discharging secretions. This gives rise to numerous problems with a blocked nose and contributes to general discomfort.

The most effective way to cure a crooked nasal septum is to septoplasty. It gives long-lasting results and recovery after the procedure is not long.
