Bottom Line: There was no difference between the three methods in the 3 groups for graft resorption.There was no change in the volume, but the weight showed a decrease in the control group.As the histological results had no statistically difference between groups, we may recommend use of these two techniques in reconstructive and in aesthetic cases.

ABSTRACT

Background: In recent years, there is an increasing tendency to use diced cartilage grafts in rhinoplasty surgery for improving dorsum contour irregularities. This study was designed to compare graft resorption between three techniques of diced cartilage using surgical blade, electrical grinder and grater in rabbit model.

Methods: Thirteen New Zealand rabbits were divided into three groups. Three 2×2 cm cartilage specimens were harvested from one of their ears. In group one, the cartilage was diced by use of No:11 surgical blade to o.5 to 1 mm cube pieces. In group two, an electrical grinder was used and in group three, a grater was applied. The grafts were placed in three subcutaneous pockets in the back of rabbits and after 12 weeks, the implants were removed and their weight and volume were recorded and were evaluated by histological techniques.

Results: There was no difference between the three methods in the 3 groups for graft resorption. There was no change in the volume, but the weight showed a decrease in the control group.

Conclusions: As the histological results had no statistically difference between groups, we may recommend use of these two techniques in reconstructive and in aesthetic cases.

Mentions: Cartilage grafts were harvested and dorsal and ventral perichondrial layers were removed from each piece of resected cartilage. They were then harvested and the cartilages were divided into three 2×2 cm pieces (Figure 2). The first piece was diced by use of No.11 surgical blade to 0.5 to 1 mm cube pieces (Group 1, Figure 3). The second piece of cartilage was diced by use of an electrical grinder (Philips. Avente) using a 50 Hz speed (Group 2, Figure 4). The third piece of cartilage was diced into small pieces by use of a grater with a special reservoir beneath it for collecting small pieces (Group 3, Figure 5). Formalin was used for sterility of instruments.
