Could my thin, previously broken nasal bones be causing my mouth breathing & worsening dark circles?

I'm 23 yo & mostly always been a mouth breather. My nose is thin w/ hump & had broken bone up top from 4 yrs ago. I had top bone ridges on thin nasal bones rasped & spreader grafts into r-side for depression. Nasal bones up top are ~1 cm wide & at bottom, bones are 2-2.3cm wide. My airways are clear tho, w/ turbinates reduced & septoplasty. I also always had dark circles (worse caz of my thin facial skin) but they seem to gotten worse over last few yrs. Thx
