Cartilage grafts are the most commonly used grafts for structural and aesthetic purposes. This study aimed to compare the viability of diced cartilage grafts wrapped in fascia with diced cartilage grafts wrapped in perichondrium. Approximately 2 x 2 cm cartilage grafts were harvested from the ears of seven New Zealand rabbits, diced to approximately 1-mm cubes, and then wrapped in perichondrium harvested from the ears or muscle fascia harvested from the right rear leg of the same rabbits. The wrapped grafts were then weighed and implanted into two paravertebral subcutaneous cavities created on the shaved backs of the donor rabbits. After 3 months, the rabbits were sacrificed and the grafts were removed, weighed and examined histopathologically. We found no statistically significant difference in the weights of the two graft types before and after embedding. The mean chondrocyte viability was 87.14 % in the perichondrium-wrapped cartilage grafts and 41.43 % in the fascia-wrapped grafts, which was determined to be statistically significant. Overall, our findings show that cartilage grafts wrapped in perichondrium led to higher chondrocyte viability and graft survival rates as compared with grafts wrapped in fascia. This method may be used as an alternative in clinical practice to provide patients requiring cartilage grafts with positive long-term effects, lower morbidity and lower costs associated with the procedure.
