Hi, I underwent a Septo rhinoplasty a year ago. 3 months post op, I started woke up with constant runny nose, Few months later, Starting having chronic post nasal drip as well. I assumed that there is some sort of sinuses issue. Got a post OP CT scan. What should be the gold standard treatment in that case? I don׳t want to make a one larger opening... Please look at the right side which seems to be damaged.
