Hello . I had surgery two and a half years ago. My surgeon said that at the same time, in order to fix the gummy smile, we will pull your nose down a little and keep it in its new position with the septum extension so that the upper lip also comes down a little. After surgery I have chronic (intermittent) congestion. Also, runny nose when eating or in cold weather. Can this change in the position of the nose be the cause of these breathing problems - is there a change in the air flow pattern?
