Effects of Different Levels of Crushing on the Viability of Rabbit Costal and Nasal Septal Cartilages

Abstract

The level of crushing determines the rate of viability for the crushed cartilage. Viability rates and the clinical properties of the slightly crushed cartilage grafts at long-term follow-up may be similar to those of the intact cartilage grafts. However, severe or significant crushing leads to a decrement in the viability of the chondrocytes and may cause unpredictable degrees of volume loss at long-term follow-up.

A Comparison of Diced Cartilage Grafts Wrapped in Perichondrium Versus Fascia

“…However, most previous studies investigating cartilage graft survival have used this technique [1,2,8,9,15]. The results of our study show the superior viability and reduced resorption rates of the perichondrium-wrapped diced cartilage grafts as compared with the fascia-wrapped graft.…”

“…The type of graft and material in which it is wrapped as well as the level of damage created during the procedure directly affect resorption rates [1,2,12]. Following the presentation by Erol of success of diced cartilage wrapped in absorbable knitted fabric, the concept of wrapping diced grafts gained popularity [3,14].…”

“…With the increased popularity of cartilage grafting, it became a necessity to solve the problems associated with the poor graft survival rates and the difficulty in shaping long-term surviving grafts. The shape of the graft, the associated preparation for the surgery and the trauma experienced during the procedure all directly affect the rate of resorption [1,2], with excessive resorption rates leading to defective contours, aesthetic deformity and patient dissatisfaction.…”

Failed Cartilaginous Grafts in the Eyelid: A Retrospective Clinicopathological Analysis of 5 Cases

“…Severe or significant crushing/kerfing has been shown to lead to a decrement in the viability of the chondrocytes and may cause unpredictable degrees of volume loss at long-term follow-up. 20,21 Preservation of the periostium also appears to be important for cartilage viability in some settings. 22 Freezing, however, has a minimal effect on chondrocytes.…”

Effect of scopoletin on fascia-wrapped diced cartilage grafts

“…The term 'cartilage graft' was first coined at the end of the 19 th century in association with nasal defect reconstruction surgeries [1]. Subsequently, various types of cartilage graft have been used by surgeons to maintain the structural integrity of a patient's body [2].…”
