Summary
Aneurysmal bone cysts (ABCs) are rare, destructive lesions. While typically found in long bones and the spine, they can occur in the mandible, representing a small percentage of jaw cysts.
Area of Science:
- Oral and Maxillofacial Surgery
- Pathology
- Radiology
Context:
- Aneurysmal bone cysts (ABCs) are uncommon, osteolytic lesions of unknown origin.
- They predominantly affect long bones and the spine.
- Mandibular localization is rare, accounting for 1% of all mandibular cysts.
Purpose:
- To review the characteristics of aneurysmal bone cysts in the mandible.
- To highlight the rarity and diagnostic challenges of mandibular ABCs.
Summary:
- Aneurysmal bone cysts are expansive, pseudocystic, and osteolytic lesions with unclear etiology.
- While typically affecting long bones and the spine, 2-5% of cases present in the mandible.
- Less than 200 cases of mandibular ABCs have been documented in English and French literature.
Impact:
- Enhances understanding of rare mandibular pathologies.
- Aids in the diagnosis and management of aneurysmal bone cysts in the jaw.
- Contributes to the literature on the epidemiology of oral bone lesions.

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...

01:29Bone 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...

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

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...

01:18The 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...
01:24Bone Formation by Endochondral Ossification
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
