title: [Allografts of cryo-preserved and radio-sterilized spongy bone tissue. Their use in orthognathic surgery].
abstract: In some circumstances, the orthognathic surgery creates inter-fragmentary spaces which have to be filled to ensure that the osteotomized segments are wedged and consolidated, and to avoid the appearance of unsightly subcutaneous contours. The authors report the results obtained through the use of cryo-preserved radio-sterilized cancellous bone allografts, coming from femoral heads, used as fillers, in diverse types of osteotomy. Thus, 19 centers of osteotomy have been filled. Follow-up periods ranged from 5 to 20 months. In 8 cases, evidence was made through radiology of the blending of the grafts. The stability of the correction was constantly noticed as well as the perfectly harmonious facial contours, which testifies the osteogenic qualities of this material. No sepsis was observed. It is a quantitatively available material, of easy shaping, the use of which does not lead to a lengthening of the operation, nor to the creation of cutaneous scars. The risk of viral transmission through allografts, specially H.I.V. and hepatitis non A - non B - non C virus is nil due to the radiosterilization.
