When Osteotomy is Done to Narrow Nasal Bones, Could the Bones Shift Back and Move?

The nasal bones certainly can move after osteotomies and is probably the most important reason not to bump your nose after rhinoplasty.  Sometimes that bones are only "greenstick fractured" and not particularly mobile.  Other times, the fracture is clean and they can be quite mobile for a couple weeks and capable to movement with light trauma up to 6 weeks.

Often a rhinoplasty does not require osteotomies. If it does, it is used to 1. close an open roof nasal base or 2. refine the dorsum. If done through an external percutaneous approach it can be carefully controlled as it does not spring back to the pre-operative position.

Nasal bone healing after osteotomy takes only 2-3 weeks to be relatively stable if the osteotomies were complete and therefore, they don't spring back.
