A 4-year-old-boy required emergent craniectomy and drainage of a large right-sided acute subdural hematoma after head trauma, during which massive sinus hemorrhage with brain swelling occurred. Acute intraoperative management entailed dural cover using synthetic dural membrane substitute and scalp coverage over the herniated brain using acellular dermal matrix. After intensive monitoring and control of raised intracranial pressure over the next few days, the exposed brain was then covered by scalp and forehead flaps with cadaveric skin grafting to the donor site. This temporary coverage continued until adequate resolution of the intracranial swelling and control of the hydrocephalus using a ventriculoperitoneal shunt. Ultimately, the flaps were derotated and the craniectomy site was reconstructed with autologous banked bone. The child had a significant functional recovery with some residual left-sided weakness. This case is the first report of local tissue flaps used for temporary coverage of malignant brain herniation in a pediatric head trauma patient and highlights their effective use. Through serial surgical procedures the brain was successfully covered without significant blood loss and the patient's local tissues returned to their original donor sites with good cosmetic outcome, without sacrifice of the patient's own skin or free flap options.
