My nose is very dry. And i can't sense air sometimes. it's cold.. and messing with my throat. None of this was brought up to me. My surgeon said no nerve branches or blood vessels were cut but my other ENT said once your tissue is cut they are gone. If that were the cause no one would get their noses done though. I have heard that nerves and blood vessels do grow back & regenerate. it's been almost a year though. ;/
