Abstract:
In recent years the term "fibro-osseous lesions" has gained wide acceptance as a general designation for certain pathological processes of the craniofacial bones. These lesions comprise a challenging group of pathologic conditions that cause difficulty in classification and treatment. Common to all of these pathologic entities is the replacement of normal bone architecture by a benign fibrous tissue composed of fibroblasts and collagen and which contains varying amounts of mineralized material. Categorization of the fibro-osseous lesions is dependent upon correlation of the patient's history, clinical findings, radiographic criteria, and histopathologic determination. This article discusses two of the most commonly confused benign fibro-osseous lesions: fibrous dysplasia and ossifying fibroma.

01:17Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...
01:27Compact 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...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
01:22Sutures 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...
