A new classification for mandibular condyle osteochondroma based on CT scans aids surgical planning. This system helps surgeons select appropriate procedures, leading to successful patient outcomes and facial symmetry restoration.
Area of Science:
- Oral and Maxillofacial Surgery
- Radiology
- Oncology
Background:
- Osteochondroma of the mandibular condyle is a benign bone tumor.
- Accurate classification is crucial for effective treatment planning.
Purpose of the Study:
- To introduce a computed tomography (CT)-based classification system for mandibular condyle osteochondroma.
- To present treatment experiences based on this classification.
Main Methods:
- A retrospective review of 61 patients with condylar osteochondroma treated between 2002 and 2012.
- Analysis of clinical and radiological data, including CT imaging.
- Follow-up periods ranging from 6 to 120 months.
Main Results:
- Two main types of condylar osteochondroma were identified: Type 1 (protruding expansion, 82.0%) and Type 2 (globular expansion, 18.0%).
- Type 1 presented with five distinct forms (anterior/anteromedial, posterior/posteromedial, medial, lateral, gigantic).
- Surgical treatments included local resection for Type 1 and condylectomy with reconstruction for Type 2, with no recurrence or new deformities observed post-operatively.
Conclusions:
- A CT-based classification system provides a valuable tool for surgical decision-making in managing mandibular condyle osteochondroma.
- The proposed classification facilitates the selection of appropriate surgical procedures, leading to favorable outcomes and restoration of facial symmetry.

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...
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
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...
