BACKGROUND: Achieving long-term structural support and smooth contouring in rhinoplasty remains challenging due to the limited regenerative capacity of cartilage and the destructive nature of commonly used graft-processing techniques. This experimental study aimed to evaluate the viability, proliferation, and survival of a novel ultra-thin "fish-scale" cartilage graft technique compared with conventional cartilage processing methods.
METHODS: Ten male New Zealand rabbits were used as an experimental model. Auricular cartilage grafts were harvested and divided into five groups: solid-block cartilage, ultra-thinned fish-scale cartilage prepared using a newly designed M-Slicer device, crushed cartilage, diced cartilage, and diced cartilage wrapped in fascia. All grafts were implanted into standardized dorsal subfascial pockets. After eight weeks, grafts were harvested for macroscopic evaluation, weight analysis, and histopathological examination using hematoxylin and eosin, Masson's trichrome, and toluidine blue staining. Statistical analyses were performed using nonparametric tests.
RESULTS: Significant differences were observed among groups regarding graft weight change, proliferation, and survival rates (p<0.01). The fish-scale cartilage group demonstrated the highest median weight gain and showed significantly greater chondrocyte proliferation and viability compared with crushed, diced, and fascia-wrapped diced cartilage grafts. Histopathological analysis revealed preserved cartilage architecture and increased peripheral chondrocyte proliferation in the fish-scale group. Fascia-wrapped diced cartilage exhibited the greatest volume loss and lowest survival rates.
CONCLUSION: Fish-scale cartilage grafts produced with minimal chondrocytic damage maximize surface area for diffusion and demonstrate superior survival and proliferation compared with traditional cartilage processing techniques. This method may offer a reliable alternative for camouflage and augmentation in rhinoplasty, potentially reducing resorption, irregularities, and revision rates.
