Management of progressive facial asymmetry owing to a rare temporomandibular joint tumour: A case report

Osteochondroma of the condyle is a rare, slow-growing, benign tumour of the temporomandibular joint that can result in facial asymmetry, limited mouth opening, temporomandibular joint dysfunction and malocclusion. The large majority of osteochondromas occur at the distal metaphysis of the femur and the proximal metaphysis of the tibia, whereas only 0.6% of osteochondromas have been reported as occurring in the craniofacial region. We discuss the diagnosis and treatment of a 56-year-old fit and well male patient who presented to the Orthodontic Department at Wexham Park Hospital with a four-year history of progressive facial asymmetry and functional concerns, owing to a rare osteochondroma of the condyle.
