  1. No treatment, if no symptoms or mild deviation. (many patients have mild deviation without any symptoms)
  2. Surgical treatment for patients with symptoms and gross deviation. There are 2 surgical options for deviated nasal septum.
  • Septoplasty
  • Submucous resection (SMR)

Now septoplasy is mostly practiced as it has cosmetic value and can be done at any ages above 7 years, but SMR cannot be done in children below 14 years of age.
