Do I expect changes to my nose shape after septoplasty?

You can also try some alternatives..below, they are non invasive

With Balloon Sinuplasty, there is no cutting of nasal bone or tissue. With Balloon Sinuplasty, ENT doctors open inflamed sinuses in the same way that heart surgeons open up blocked arteries during balloon angioplasty. The procedure is less invasive than traditional sinus surgery, and effective at relieving symptoms of chronic sinusitis. Balloon Sinuplasty allows patients to return to normal activities quickly. Unlike conventional sinus surgery, it does not include removal of bone or tissue from the nose. And, Balloon Sinuplasty is now offered by some doctors in their office under local anesthesia, so that there is no need to go to an operating room or undergo general anesthesia.

While recovery time varies with each patient, recovery is typically fast. In a study of in-office balloon dilation, most patients returned to work and normal activity within 2 days.

However, even I am suffering the same since childhood, though in my case it is just moderate.

Again, in my experience, I have also seen patients find no relief in Sinoplasty but still its far better and you get immediate relief to a major extent in most cases.

See its like this there are chances you will get completely cured or in case the symptoms might return as well.

Its just sometimes you are body is susceptible to DNS.

So, in the long run if you have the time and patience and believe in holistic healing, then I would suggest you go for Yoga and practice breathing excercise also called Pranayam.

Some of them are alternative nostril breathing (AnilomVilom) and Kapalabhati. With these techniques you can surely get cured of your DNS but it will take around 6 months to 1 year. But life long you will be cured. You just have to find a right Yoga Guru and you have to increase the intensity of the breathing excercise as you start.

Also Neti Pot ( Please Google -Nasal irrigation), is excellent. It hardly takes 5 minutes everyday. It might be hard in the beginning but don't give up. Surely, if you get a Good Yoga Teacher he can help you in 3-6 months time.

This is my experience. Now I am just doing Neti Poti and I am fine but I have to do it religiously without missing.
