Osteochondroma of the mandibular condyle is a relatively rare condition, which is composed of cartilage and boney tissue.

Cartilage-Forming Tumors

Cartilage tumors account for the majority of primary bone tumors and are characterized by the formation of hyaline cartilage—fibro cartilage and elastic cartilage are rare components. Benign tumors are much more common than malignant ones.


Benign tumors cause a progressive enlargement of the condyle, resulting in facial asymmetry, TMJ dysfunction, limited mouth opening and imperfect positioning of the teeth when the jaws are closed. Pain is rarely associated with this tumor.


Radiographs demonstrate a one-sided enlarged condyle with the tumor growing beyond the tissue of the condylar head.


Surgical intervention is indicated to remove the tumor and therefore stopping the benign growth process while at the same time improving facial symmetry, jaw function, and symmetry while jaw is closed.


Reoccurrence is rare and a favorable outcome is very likely.
