still difficult to breathe, even after surgeries. plz help

I am a 22 yr old female. I have had my deviated septum corrected, and a functional rhinoplasty, and still have trouble breathing through my nose, so i continue to mouth breathe during the day and at night time (which negatively affects my sleep).  I tell my ENT doctors it feels like my airways are TOO narrow, like im breathing through little tiny straws.  They say "oh well theres nothing in the way like your septum or polyps"  I know there isn't anything in the way!! Isn't there a way to make the narrow parts of my airway bigger like by spreader grafts or something?  I've tried nasal dilators, cpap, you name it.  Its getting so old, and no im not congested and dont have rhinitis.  If anything im congested because my nose is soo narrow that mucous can't get through.  Also, I was born two months prematurely, and had sleep apnea as a baby (because i couldn't breathe through my nose then either).  The only time i felt like I could breathe through my nose was after my septoplasty when the splints were in my nose.  Once the surgeon took them out it was back to mouth breathing.  I'm assuming where the splints were placed is the narrow part of my airway and the splint stretched out that area.  Please any input would be great im desperate.

Since you've tried the ENT's , I'll suggest an alternative.  Go to the drugstore, get a Neilmed Sinus Rinse, but don't use the packets provided, unless it has instructions to make the saline hypertonic.  To make hypertonic saline, get a gallon of distilled water, add 12 teaspoons of non-iodized salt, shake until dissolved.  Use the Neilmed.  Hypertonic saline shrinks the tissues of the nose and sinuses, at least temporarily, if you are lucky, longer. It will not damage your nose.  If the Neilmed doesn't clear everything, try my Flip-Turn Sinus Flush.  It's risky, because you have to bend over in a shower, but you are young.

I know how you feel.  Due to years of allergies, vague sinus congestion, and finally severe chronic sinusitis, I had completely forgotten that it was possible to breathe with my mouth closed.  After I invented the Sinus Flush, I'd have so much air coming through my nose it would wake me up at night.
Like I said, you may just get temporary relief, but there is a chance you will become normal.
