My septum is deviated 1-2mm. Is this worthy of surgery?

Everyone has a minor deviation of their septum from 1-2 mm. To document medical necessity, there has to be significant symptoms of nasal obstruction to warrant undergoing a surgical procedure to improve air flow through the nose.  For more information, please see link below

The vast majority of people have some degree of minor septal deviation and in these cases, most do not have any associated symptoms (difficulty breathing through nose), or at least enough not to warrant surgery. Ultimately, it comes down to your own symptoms and if your septal deviation is significant enough to cause nasal obstruction. If not, then surgery is not indicated. Additionally, there can be other reasons to have nasal obstruction including seasonal allergies and chronic sinusitis. I would recommend having a formal consultation with an otolaryngologist or facial plastic surgeon  to examine your nose and discuss options. 

Unfortunately, your question can't be answered over the internet. How do you know it is 1-2 mm deviated? Are you having trouble breathing? Have you had an examination by an ENT or Facial Plastic Surgeon? The bottom line - If you're breathing fine, don't pursue surgery. Best of luck.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

One to two mm of septal deviation, by itself, warrants no surgery. There needs to be a functional issue or a cosmetic problem caused by the deviation to need corrective surgery
