Fig. 2. Fused preoperative (blue) and postoperative (orange) cone-beam computed tomography scans in coronal (A) and axial (B) views: the resection defect in the upper jaw on the left side is highlighted in blue. Note: the swelling of the mucosa in the maxillary sinus. However, no bone reaction (such as bone loss or resorption, osteolysis, or osteosclerosis) could be found. Therefore, this patient was preoperatively classified as stage I. However, postoperatively the lesion should certainly have been classified as stage III because the floor of the maxillary sinus had to be removed. Preoperative clinical information (size of the mucosal defect) offers no conclusion about the severity of the bone disease.
