Abstract Background Bone scintigraphy was performed to monitor anastomotic patency and bone viability. Methods In this retrospective study bone scans were carried out during the first three postoperative days in a series of 60 patients who underwent microvascular bone grafting for reconstruction of the mandible or maxilla. Results In our series early bone scans detected a compromised vascular supply to the bone with high accuracy p 10-6 and a sensitivity that was superior to the sensitivity of clinical monitoring 92 and 75 respectively . Conclusion When performing bone scintigraphy during the first three postoperative days it not only helps to detect complications with high accuracy as described in earlier studies but it is also an additional reliable monitoring tool to decide whether or
