Histologically, OC needs to be distinguished from osteoma, benign osteoblastoma, chondroma, and chondroblastoma.

Condylar OCs are frequently situated on the anteromedial surface of the condylar head.

A conservative condylectomy with articular disc repositioning combined with orthognathic surgery is an acceptable option for treatment of condylar OC.
