Cartilage regrowth with perichondrium

Cartilage regrowth is a controversial and exciting frontier in facial plastic surgery.  Several studies have found regrowth of costal cartilage when remnants of cartilage are placed back in the donor site.  This has also been described in septoplasty surgery for the nose.  In theory, if crushed cartilage was placed back in the area cartilage may regrow.  However, anecdotal evidence suggests that this is not likely.

In theory it can but it usually doesn't. If cartilage had not reformed within six months of harvest, it will not do years later.
