An Adhesion of Cartilage to Silicone Block using Histoacryl Glue

ABSTRACT

Plastic surgeons have been in pursuit of natural appearance in rhinoplasty, which means harmonious relationship between nasal tip and dorsum. If silicone implant is used alone for the augmentation of the nasal tip, there is a possibility of the thinning of the nasal tip skin and exposure of implant. For these reasons, plastic surgeons have used a cartilage fixation over the silicone implant for nasal tip augmentation. However, fixation by sutures is technically challenging, so authors tried to use Histoacryl glue instead of sutures. Twelve New Zealand white rabbits were used in this study. Four 5mm diameter and 1mm thick cartilages were harvested from ear. Two cartilages were fixed to the silicone blocks by chromic catgut and the others were attached by Histoacryl glue. Four cartilage-silicone complexes were implanted into the subcutaneous pocket of the rabbit's head. In the 1st, 3rd and 5th week, the cartilage- silicone complexes were harvested and the shearing forces between cartilages and silicones were measured by texture analysis. The shearing forces were not changed in the Histoacryl group with the lapse of time but decreased in the suture group. However, the difference between the 2 groups were not statistically significant. The histologic findings of both groups showed progressive fibrosis. This study showed the possibility of using Histoacryl glue as a simple method of fixing cartilage to the silicone.
