Deviated septum or deviated nasal septum is a physical disorder of the nose ,involving displacement of the nasal septum. The wall between the nostrils is called your nasal septum. The septum is made up of bone and cartilage. When this cartilage or bone is off-center (deviated to one side) or crooked, it is referred to as a deviated septum. Only more severe cases of a deviated septum will cause symptoms of difficulty breathing and require treatment.
Most people do not have a perfectly straight septum, but it may be misaligned due to a two main causes, A person can be born with a deviated septum (congenital), or it can bend due to normal growth during childhood, Another cause of deviated septum is injury or trauma, such as a broken nose. It is most frequently caused by impact trauma, such as by a blow to the face. It can also be a congenital disorder, caused by compression of the nose during childbirth. Deviated septum is associated with genetic connective tissue disorders such as Marfan syndrome, Homocystinuria and Ehlers–Danlos syndrome.
If you have a deviated septum, you will need a type of surgery called septoplasty. In this procedure, the surgeon will move your septum to a normal position. In some cases, the surgeon also will reshape the external appearance of your nose in a procedure called rhinoplasty. When the two procedures are done at the same time, the surgery is called a septorhinoplasty. In mild cases, symptoms can simply be treated with medications such as decongestants, antihistamines, and nasal spray. Medication temporarily relieves symptoms, but does not correct the underlying condition.
