Introduction:
Juvenile ossifying fibroma is a rare, benign fibro-osseous tumour. In the light of a clinical case, the authors review the diagnosis, treatment and histological classification of these tumours.
Case Report:
A seven-year-old child presented with a naso-orbito-ethmoidal trabecular juvenile ossifying fibroma. Complete surgical resection via a transfacial approach was performed after a preoperative work-up comprising head and neck CT and MRI.
Discussion:
A review of the literature reveals that treatment of this aggressive tumour must comprise complete surgical resection via an incision determined by local tumour extension.
Conclusion:
Patients with juvenile ossifying fibroma tumour require long-term follow-up due to the high recurrence rate.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
