A deviated septum is a medical condition where the nasal septum, the cartilage and bone that divides the nasal cavity into two nostrils, is displaced or crooked.
This deviation can obstruct one or both nasal passages, leading to symptoms like nasal congestion, difficulty breathing through the nose, snoring, and recurrent sinus infections.
Deviated septums can be congenital or result from injury.
Treatment may involve medications to alleviate symptoms or surgical procedures, such as a septoplasty, to correct the deviation and improve nasal airflow.
