My nose is perfect but one nostril is way bigger than the other one (I was born like this) and I would like to make it smaller like the left size. Is it possible? How much would it cost? Could the insurance cover it?
Unless your nostril size interferes with breathing, it is not likely that insurance will cover it. Best to see a Board Certified Plastic Surgeon to evaluate and give an opinion in person.
Most likely insurance will not cover this although your surgeon could try and ask for pre-approval. In theory this could be improved with surgery, but the scope of the surgery would depend on whether the tip or lip were also involved to some degree. Best of Luck Dr Harrell
