Purpose:
To evaluate outcomes of total subcondylar excision of mandibular condylar osteochondroma.
Patients And Methods:
Two adult patients presented with progressive facial asymmetry, jaw deviation, and limited mouth opening. Computed tomogram (CT) showed a large osseous tumor arising from the right condyle occupying the subtemporal space in these patients. Complete surgical excision was performed without condyle reconstruction. The pathology report indicated osteochondroma. Patients were followed for an average of 5 years.
Results:
Long-term evaluation showed restoration of dento-occlusal function and facial appearance. Follow-up CT showed a partly regenerated and remodeled condyle. Patients' chewing function was acceptable, but predominantly on the lesion side.
Conclusions:
Condylar osteochondroma caused jaw deviation and joint dysfunction. Complete surgical excision achieved an adequate long-term outcome, but condylar reconstruction is advisable.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Bone 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...
