Video Summary

In this video summary, Tommi Koronen presents the findings of a study on bone flap reabsorption in patients with cranioplasty following decompressive craniectomy. The aim of the study was to assess the long-term outcome and risk factors of bone flap reabsorption. The study included 45 patients who underwent cranioplasty and were followed up with CT scans. It was found that over 90% of patients experienced some level of bone flap reabsorption, with less than 80% bone volume remaining in almost a third of patients. The extent of reabsorption did not depend on the length of follow-up, and patients younger than 30 had less remaining bone volume. The study suggests that routine CT scans for monitoring bone flap reabsorption may not be necessary.
