I Am a 21 Year Old Woman with a Cleft Lip and Palate, Can My Nostrils be Fixed?

I had no air flow from my left nostril until about 4 years ago. I have had 4 nose surgeries to work on my deviated septum and to open air flow. The air flow is still not good and I am wanting my nostrils to be symmetrical as my left one (on the side of my cleft lip) is much smaller. I want to know if this is possible. I have seen the top craniofacial/cleft lip surgeon in Houston since I was born. He has done an alright job but when I have asked him to work on my nostrils he hasnt. Can it be done?
