Spontaneous Bone Flap Resorption Following Cranioplasty Using Autologous Bone.

Cranioplasty is a common neurosurgical procedure. The main reasons for performing cranioplasty are, in addition to aesthetic correction and protection of the brain, the reestablishment of the adequate flow of cerebrospinal fluid and the prevention of complications inherent to the perpetuation of bone failure. In our institution the patient's autologous bone remains the best method for performing cranioplasty, despite the existence of other heterologous grafts and bone substitutes. Despite representing for us, the best material for cranioplasty, the use of autologous grafting is subject to complications. In this paper, the authors present the case of a patient who underwent cranioplasty with autologous bone that progressed with spontaneous resorption of the bone flap. The authors herein briefly discuss the case and review the literature on the subject, with an emphasis on the factors that can lead to such an outcome.
