“…60,80,91,114 Additionally, there have been limited reported cases on the tendency of children to suffer aseptic resorption of sterilized bone flaps, which is hypothesized to be attributable to an array of possible causes, from inherent hyperactive cellular responses to the degree of calvarial thickness in this subpopulation. 41,45,51 Disillusionment with autologous bone cranioplasty continues to exist given the propensity for resorption (reported rates are as high at 50% across all age groups), 8,41,113 inadequate contouring, debate over optimal means of bone flap preservation, 5,50,83,95 and potential for donor-site morbidity; these in sum continue to limit the use of this biomaterial for a broader spectrum of patients. 15,120 allografts Sicard, Dambrin, and Roger introduced the use of cadaveric skull in cranioplasty during the latter half of the 1910s.…”
