[Experimental study on repair of cricoid cartilage defect with cartilage grafts in rabbits].
OBJECTIVE
To investigate the effect of free cartilage fragment in repair of cricoid cartilage defect.


METHODS
One-third of cricoid cartilage was cut and repaired with free thyroid cartilage fragment and pedicled cartilage in rabbits. The pathological changes of the cartilages were observed.


RESULTS
1. The free thyroid cartilage fragments were absorbed in two months, and were replaced by scars. 2. The pedicled cartilage fragments were not absorbed and healed with the cricoid cartilage. 3. No evidence of growth impairment of surgery-induced cricoid cartilage was observed.


CONCLUSIONS
In rabbits, both free cartilage fragments and pedicled cartilage fragments could repair the defect of cricoid cartilage effectively.
