Abstract (original English)
Objective Chondrocutaneous composite grafts figure among the reconstruction alternatives for alar rim defects resulting from tumor resection and trauma. The major problem with composite grafts is the limited graft survival area. In the present study, the authors aimed to increase the survival area of composite grafts by utilizing the ability of stem cells to promote neovascularization which is crucial in composite graft viability. Methods The study included 36 adult Wistar Albino rats, which were allocated to 6 groups. Groups 1, 2, and 3 were the groups in which the grafts were implanted immediately after the defect was formed, and Groups 4, 5, and 6 were those in which grafts were adapted 4 days after the defect was formed. Composite grafts of 1 × 1 cm containing both the cartilage and the skin were prepared from 1 ear, and after forming punctures and incisions on the cartilage, the grafts were adapted to the 1 × 1 cm defects on the back. The backs of the rats in groups 1 and 4 were injected with adipose-derived stem cell (ADSC), those in groups 2 and 5 with medium solution, while the rats in Groups 3 and 6 did not receive any injection. The procedures were followed by histopathological and scintigraphic evaluations. Results An evaluation of the statistical results showed that composite graft survival areas of the group treated with stem cells increased significantly, in compa
