Osteomosis, my nose is very wide and flat. Will it narrow if ostemosis wasn’t preformed after my hump removal? (photo)

The bridge of your nose is like an "A-Frame" roof top, and removing the bump may lead to widening, also called an "open roof". A month postoperative may be too soon to evaluate your nasal width. Certainly discuss your concerns with your rhinoplasty specialist to see what might be best for you moving forward. Hope this helps! Dr Joseph

Osteotomies (controlled cuts or fractures of the nasal bones) are routinely performed after hump removal to close the "open roof" created when a hump is removed.   Imagine your nose is a house with a triangular roof.  If a portion of the roof is removed, you will now have a square or flat roof.  The "walls" of the nose need to be brought in to recreate the normal anatomy and narrow the nose.  Flat spots or a poorly defined nose can result without this critical step. 

It is a little hard to tell from the photos, but swelling is definitely normal at this point in the recovery process. Be sure to discuss your questions with your surgeon and if the wideness doesn't settle down to your liking, then it is always possible to seek another opinion with a rhinoplasty specialist.
