Purpose:
Aneurysmal bone cysts (ABCs) are benign osteolytic lesions that occur relatively rarely in the jaws. The aim of the present study was to investigate the clinical and radiographic characteristics, pathologic features, and treatment results of ABCs of the jaws (JABCs).
Materials And Methods:
A retrospective analysis of a 20-year database, including 17 cases of JABC, was performed.
Results:
A total of 17 patients, 9 males and 8 females, aged 7 to 47 years (mean 20.4, median 14), were included. Of the 17 lesions, 15 (88.2%) were located in the mandible and 2 (11.8%) in the maxilla. A painless (12 of 17, 70.6%) or painful (3 of 17, 17.6%) swelling was the most common clinical finding. The pathologic analyses revealed that 13 JABCs (76.5%) were secondary in nature, including 11 cases associated with ossifying fibroma. Radiologically, the lesions frequently presented as multilocular (58.8%), well-defined (70.6%) radiolucencies (82.4%). Two lesions (11.8%) recurred.
Conclusions:
Our results suggest that most JABCs are secondary in nature and frequently associated with ossifying fibroma. The patients with JABCs presented with various clinical and radiographic features and therefore often posed a diagnostic dilemma. Resection is the preferred treatment of JABCs.

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...
Gross 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...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
