Completely resorption of autologous skull flap after orthotopic transplantation: a case report.

Autologous skull flaps were frequently used in craniotomy, and after craniotomy, autologous skull flaps need to be replanted in situ at most of the time, and complications such as infection and resorption may occur. Ultimately, resorption may result in dislocation of the autologous skull flaps. Here we describe a case of completely resorption of autologous skull flap shortly after orthotopic transplantation which required an extra cranioplasty and potential causes were discussed. Improper processing procedure such as peeling periosteum excessively before replantation, and postoperative subdural effusion and the use of bone wax were considered to be responsible for the rapid complete resorption of the skull flap.
