I have been googling and searching high and low about the chances of rib/nasal/septum cartilage nasal graft being dislodged (not on its own) due to external traumas, eg. a shoulder bump into your face in a crowded place or even something as extreme as a punch to the face; but have yet to find a definite answer.
In another words, to what extent does " time will allow tissues to be incorporated into the graft " prevent shifting due to future traumas.
really hope to hear from fellow PSers.
