Bone Flap Preservation in Subcutaneous Abdominal Pocket for Decompressive Craniectomy

Abstract

Summary:. We report our experiences of two pediatric cases in which a bone flap was preserved in the subcutaneous abdominal pocket for decompressive craniectomy. In one case, the bone flap was divided and preserved for cranioplasty without complications; in the other case, the bone flap was left intact as one piece. In pediatric patients, the storage space for a bone flap is sometimes difficult to achieve, and the technique described herein is useful in such situations. Notably, because the bone resorption rate with cryopreservation is higher in pediatric patients, in vivo preservation may be more useful in this population.
