DNS in medical terms stands for Deviated Nasal Septum. It is a condition where the thin wall present between the nasal passages is displaced or deviated from the center of the nasal cavity. Almost 80% of people are born with some or the other deviation, but most of these deformities may not create any symptoms or come to notice. However, DNS may cause the following symptoms:

• Nasal obstruction
• Anosmia (inability to smell)
• Sinusitis
• Epistaxis (nosebleeds)
• External deformity
• Middle ear infection

ENT treatment for DNS depends on the type of deviation involved. If the deviation is slight with not many symptoms, then no treatment is necessary. If there is mechanical obstruction with difficulty in breathing, then septoplasty is performed. In this procedure, the septum is either straightened or repositioned to the middle of the nose. DNS cannot be prevented, and minor deviations do not require treatment. Symptomatic DNS can be corrected by surgery through the nostrils under local or general anesthesia.
