Allogenic lyophilized cartilage grafts for craniomaxillofacial reconstruction

Allogenic lyophilized cartilages were made in our clinic after Sailer methods and some modification. In our clinic, we have used allogenic cartilage grafts on 102 defects of craniomaxillofacial area; 1) for defects from cyst or ameloblastoma, 2) for lack of continuity of the mandible, 3) for rhinoplasty, 4) for paranasal augmentation, 5) for augmentation genioplasty, 6) for reconstruction of orbital floor, 7) for oroantral fistula, 8) for temporal augmentation, 9) for TMJ surgery 10) for condyle defect as a costochondral graft, 11) for filling of tooth socket and alveolus augmentation,12) for correction or orbital height and 13) for guided bone regeneration in peripheral implant. The types of lyophilized cartilage used were chip, sheet and block types developed by freeze-dried methods. Some grafts showed change of ossification, in which case we could perform implant on it. We have good results on reconstruction of craniomaxillofacial defects. Allogenic cartilage have advantages such as 1) it has no immune reaction clinically, 2) it is more tolerable to infection than that of autogenous cartilage, 3) it has character of less resorption which require no over correction, 4) it is easy to manipulate contouring, and 5) it has possibility of undergoing ossification. Allogenic cartilage has been considered as good substitutes for bone. The author would like to report the results on 102 allogenic cartilage have
