Comparison of outcomes using diced cartilage with or without tensor fascia latae wrapping in rabbits.
BACKGROUND
Diced cartilage has been associated with several advantages and rewarding results, leading to its widespread application in various forms in rhinoplasty, but the outcomes of diced cartilage with and without tensor fascia latae wrapping have not been widely reported in evidence-based articles.


OBJECTIVE
The authors compared changes in weight, size, and histology of both bare and fascia-wrapped diced cartilage in rabbits as a model for human surgical outcomes.


METHODS
One auricle from each of 15 rabbits was divided into 2 pieces, and both samples were diced. The tensor fascia latae of the rabbit was wrapped around 1 cartilage specimen from each rabbit (group A specimen); the other specimen received no wrapping (group B specimen). A group A specimen and a group B specimen were implanted into separate subcutaneous pockets in each rabbit. After 3 months, samples were removed from the recipient beds and weighed to compare pre- and postoperative weights. All specimens were examined for evidence of cartilage viability by histologic methods.


RESULTS
There was a significant decrease in the weight of cartilage in group A. A nonsignificant weight increase was observed in group B. Histologic analyses of 5 parameters revealed no significant differences between the 2 groups, except for a significantly greater amount of new cartilage formation in group B.


CONCLUSIONS
Any type of wrapping around diced cartilage may inhibit its access to surrounding nutrients. Dicing increases the absorption surface, which may result in some overgrowth, but wrapping may have a negative impact on the viability of the diced cartilage.
