An Unusual Complication of Bone Wax Utilization

Abstract Bone wax is a commonly used hemostatic agent with minimal complications. Some of the known complications include inflammation, granuloma formation, infection, and impaired osteogenesis. Several clinical reports of bone wax migration have also been reported. In this paper, the authors present a rare patient of bone wax migration intracranially in a 6-year-old patient who initially underwent craniotomy for the evacuation of subdural hematoma and repair of depressed skull fracture. The patient then underwent craniotomy scalp scar revision several months later. Postoperatively he developed short-term memory loss, apraxia, and word finding difficulties. The imaging findings were consistent with the presence of a foreign body centered in the posterior aspect of the left middle temporal gyrus, which was surgically removed and found to be bone wax. The patient recovered well with complete improvement of his neurologic symptoms.
