Hi Starwars,
A nose, 14 weeks after rhinoplasty is Gold's Gym strong. Nasal bones heal rather quickly, that is why if a nose has an acute displaced fracture (from the front the nasal bones appear to be way East or West of the midline), it needs to be evaluated within 5 days (once the swelling has gone down) and the bones should be relocated to their natural position ideally between 5 and 10 days, but up to 18 days. Beyond that time frame, the bony segments most likely will need to be re-fractured with a chisel.
At 14 weeks after rhinoplasty, the bones are solid, but just like nasal bones that have never been operated upon, they should not be exposed to trauma without the risk of breaking. As I recently told one of my rhinoplasty patients named George J., "Watch out for that tree!" Good luck and be well.
Dr. P
