Can grafts fail to grow and if so, why?

The three most common causes of graft failures includes (1) exposure to air for more than 15 seconds when placing the grafts or when preparing the grafts, (2) rough handling of the grafts during placement, (3) a recipient site that is too tight.  These problems most frequently arise when the surgical team is sloppy, inexperience, poorly supervised, has no quality control systems in place implemented by the surgeon.
