Permanence of Diced Cartilage, Bone Dust and Diced Cartilage/Bone Dust Mixture in Experimental Design in Twelve Weeks

Abstract

Bone dust and diced cartilage are used for contour restoration because their minimal donor site morbidity. The purpose of this study is to investigate permanence of bone dust, diced cartilage and bone dust/diced cartilage mixture in rabbits over 12 weeks. New Zealand white rabbits were used for this study. There were three groups in the study: Group I: 1 mL bone dust. Group II: 1 mL diced cartilage. Group III: 0.5 mL bone dust + 0.5 mL diced cartilage mixture. They were placed into subcutaneous tissue of rabbits and removed 12 weeks later. The mean volumes of groups were 0.23 +/- 0.08 mL in group I, 0.60 +/- 0.12 mL in group II and 0.36 +/- 0.10 mL in group III. The differences between groups were found statistically significant. In conclusion, diced cartilage was found more reliable than bone dust aspect of preserving its volume for a long period in this study.

Evaluation of Diced Cartilage Grafts Shaped with Three-Dimensionally–Printed Bioresorbable Polycaprolactone Molds

“…However, concerns on the use of block cartilage grafts, such as the unpredictable amount of absorption, visibility under the skin, exposure from the skin, limited donor area, difficulties encountered in shaping the graft, and the need for revision because of evident bending, limit the use of these grafts. 1–5…”

“…However, concerns on the use of block cartilage grafts, such as the unpredictable amount of absorption, visibility under the skin, exposure from the skin, limited donor area, difficulties encountered in shaping the graft, and the need for revision because of evident bending, limit the use of these grafts. [1][2][3][4][5] These disadvantages of block cartilages emphasize the use of diced cartilage grafts. Erol 6 used the method known as "Turkish delight" to repair nasal dorsum deformities by wrapping diced cartilage grafts in Surgicel (Ethicon, Inc., Somerville, N.J.).…”
