Summary
Aneurysmal bone cysts (ABC) are rare jaw lesions, typically affecting young females and the mandible. Careful curettage is an effective treatment, with recurrence rates similar to resection.
Area of Science:
- Oral and Maxillofacial Surgery
- Pathology
- Oncology
Background:
- Aneurysmal bone cyst (ABC) is an osteolytic bone lesion.
- Jaws are rarely involved, with 92 cases of Jaws ABCs (JABCs) reported.
- JABCs predominantly affect individuals in the first two decades of life, with a slight female predilection.
Purpose of the Study:
- To review the clinical and radiographic features of JABCs.
- To analyze treatment outcomes and recurrence rates.
- To highlight diagnostic challenges associated with JABCs.
Main Methods:
- Literature review of 92 detailed JABC cases.
- Analysis of epidemiological data, clinical signs, and radiographic features.
- Comparison of recurrence rates based on surgical techniques (curettage vs. resection).
Main Results:
- JABCs most commonly affect the mandible (68.5%), particularly the ramus.
- The most frequent clinical sign is bone swelling (painless or painful).
- Radiologically, JABCs typically appear as radiolucencies (93.8%), often multilocular (69.4%).
- 15.2% of JABCs were secondary, with 8 cases linked to fibrous dysplasia.
- Recurrence rates did not significantly differ between curettage (15.2%) and resection (11.8%).
Conclusions:
- JABCs present diverse clinical and radiographic features, posing diagnostic challenges.
- Secondary JABCs can occur, sometimes associated with other bone conditions.
- Careful curettage is a suitable treatment option for JABCs, with comparable recurrence rates to resection.

01:26Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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...

01:18The Bone Matrix
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:27Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
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...
