Ethmoid sinus disease: CT evaluation in 400 cases. Part III. Craniofacial resection

Abstract

Of 400 patients with ethmoid sinus disease, 18 had undergone craniofacial resection. This operation is an aggressive surgical procedure directed at total en bloc extirpation of tumors that extend through the floor of the anterior cranial fossa. Recent advances in surgical technique have made it the procedure of choice for sinonasal tumors that extend through the cribriform plate, fovea ethmoidalis, and orbital roof. Specifically, this operation has had excellent results in patients with esthesioneuroblastomas. Radiologists must be aware of the possible pitfalls in interpreting the postoperative computed tomographic scans and the findings that suggest tumor recurrence.
