[Xenogenic cartilage as a transplant for reconstruction of the facial skull].

90 patients were followed-up, in whom 110 cartilage grafts of bovine origin (Chondroplast) had been inserted. Nose and orbit (46 and/or 32 cartilage grafts) were the most frequent implantation sites. In three out of those 90 patients incorporation of the grafts was eventful. In two out of those three complication finally resulted in a loss of the graft. When following-up in 57 patients whether the grafts had kept their shape we found out that the cartilage grafts had still kept their shape quite well after three and a half years in 50 patients.
