As cartilage is an ideal natural material for transplantation, its use in the ENT surgery is limited by a difficulty to get proper shape of cartilage implants. Aim of the work is to make ring-shaped cartilage implants, to check their stability after laser reshaping and to perform transplantation into rabbits in vivo. We experimented with costal cartilages of 1-2 mm in thickness obtained from 3rd and 4rd ribs of a rabbit. 1.56 μm laser (Arcuo Medical Inc.) was used for cartilage reshaping. The laser settings were established taking into account anisotropy of cartilage structure for different orientation of the implants. The reshaped cartilage implants were surgically sewn to rib cartilages of the other rabbits. The rabbits were slaughtered in 3.5-4 months after surgery. The results have shown that (1) all reshaped implants kept circular form, and (2) the implants were adhered to the native rabbit cartilage sites (3) pronounced signs of regeneration in the intermediate zones were observed. The prospects of the cartilage implants use in larynx stenosis surgery are discussed.
