[Computed tomography following facial surgery].
During the first four to six weeks after surgery, a reaction in the paranasal sinuses can be demonstrated by CT. Similar opacifications appearing later were due to tumor recurrency. Tumor recurrency leads to an increase of soft tissue structures, disappearance of vascular structures, and an increase of bone destruction. The bone destruction can show characteristic fragmentation, with the fragments at a certain distance from each other. If the recurrence is known, CT shows the extension, similar to normal preoperative CT. Follow-up examinations improve safety of interpretation.
