I am 6 month Post OP and my voice changed. It is as if there is more air-resistance in the epipharynx space, which makes talking very tiring after a while. Only when I lay down in bed it seems as if the upper area of the nose opens up more (as if I used spray which I dont) and makes breathing easier.Due to the nose Job my sidewalls were broken and pushed together and I still have some swelling in the nose. What causes this air resistance and the twang, why does the nose open up after lying down?
