The viability of cartilage grafts has been well documented; however, controversy still exists about the viability of crushed cartilage. Recently, there has been a tendency to use diced cartilage grafts wrapped with oxidized regenerated cellulose (Surgicel) sheets for improving dorsal contour in rhinoplasty. The viability of diced cartilage grafts and the effect of Surgicel on cartilage grafts are not well known. In this study, we used ear cartilage from 18 Neu, Zealand rabbits. Cartilage grafts were transplanted to surgically created subcutaneous pockets on the back of the rabbits on both the left and right sides. There were three groups: (1) intact cartilage grafts, (2) crushed cartilage grafts, and (3) diced cartilage grafts. The grafts that were transplanted to the right side were wrapped with Surgicel. Cartilage grafts in all groups were viable. In grafts that were wrapped with Surgicel, a marked increase in the collagen content was investigated. Grafts that were wrapped with Surgicel demonstrated no evidence of proliferation, whereas the bare cartilage grafts demonstrated significant amounts of proliferation.
