[Benign fibro-osseous tumors of the frontal skull base with intracranial extension. Report of 2 cases].

We report on two patients with ossifying fibroma of the anterior skull base with intracranial extension. A psammomatoid ossifying fibroma was removed from a 29 year old female patient, and in a 37 year old female patient a cemento ossifying fibroma was removed. The main clinical symptom in both cases was headache. Surgery took place after diagnosis and therapy in an interdisciplinary operation with ENT colleagues. The ossifying fibroma is a benign neoplasm mainly affecting the maxilla and mandible. Complete removal is better than a curettage of the tumor.
