Abstract:
Juvenile ossifying fibroma (JOF), is a rare fibro-osseous neoplasm that arises within the craniofacial bones in individuals under 15 years of age. The term is used in the literature to describe two distinct histopathologic variants of ossifying fibroma of the craniofacial skeleton. It was described as a cellular and aggressive form of ossifying fibroma usually affecting children as 'the lesion proliferates, grows, invades and destroys tissue until the eyes are extruded and the cerebrospinal space is entered'. In the present case, because the lesion was well circumscribed and it was non-infiltrating into the adjacent bone and causing cosmetic and functional problems, surgical excision of the tumour mass was performed. A satisfactory facial appearance and an optimal restoration of function were achieved after the surgical procedure. After 3 months of follow-up, there was no recurrence.

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...
