My nasal bones are wider after rhinoplasty. Is this common, and if so, what causes it?

I had an open rhinoplasty preformed three weeks ago. One of the things that my surgeon, did was bring the nasal bones closer together towards to top of my bridge. When he first took the splint off, it looked amazing, even though I was swollen. Now it has been two weeks since the splint has been removed, and the nasal bones on my bridge look like a bit wider than they did after the splint was first removed. Is this common, or possible? And if so, what causes this? Thank you.
