[Allotransplantation of cryopreserved fetal cartilage in plastic surgery]
1Department of Plastic Surgery, Affiliated Hospital of Bengbu Medical College, Bengbu 233004.
Objective:
To study the applicability of homologous fetal cartilage in plastic surgery.
Methods:
Limb and costal cartilage were taken from the dead fetus. The fetal cartilage was then frozen at -80 degrees C and preserved in -196 degrees C liquid nitrogen with a cryoprotective agent. A total of 38 patients received fetal cartilage transplantation. Of them there were 24 saddle nose, 4 auricle defects, 6 secondary deformities of cheiloschisis, 4 mandible deformities.
Results:
Through follow-up of three and a half years, it was found that none of the transplanted cartilage was absorbed, deformed or rejected due to immunological reaction. The contours were satisfactory except 2 cases with auricle reconstruction.
Conclusion:
The clinical application of homologous fetal cartilages is of value in plastic surgery.
