Replantation of an avulsed zygomatic bone as a freeze-preserved autologous graft: a case report

We describe a very rare case of midface fracture where the zygomatic bone had been completely avulsed. The fragment was preserved in a frozen state for 40 days, then replanted and the graft was taken. The conditions favourable for the taking of the freeze-preserved zygomatic graft were: (1) an appro...

Description
Summary:We describe a very rare case of midface fracture where the zygomatic bone had been completely avulsed. The fragment was preserved in a frozen state for 40 days, then replanted and the graft was taken. The conditions favourable for the taking of the freeze-preserved zygomatic graft were: (1) an appropriate preservation method, (2) conservation of the periosteum on the zygomatic bone, (3) diversity of the haemodynamics of the zygomatic membranous bone, (4) immobilization of the zygoma by rigid fixation, and (5) a rich blood supply at the recipient site.
