A case of synovial chondromatosis of the TMJ: treatment based on stage of the disease.

: A patient with synovial chondromatosis of the temporomandibular joint extending to the preauricular skin, parotid, and infratemporal fossa was operated and followed with a stable remnant, for 2 years postoperatively. In light of literature and what the authors have learned from this case, the authors emphasize stage of the disease as a risk factor for recurrence. The long history of symptoms, calcified and conglomerated radiological appearance of the lesion, and extensive involvement of the joint and periarticular area of this case indicate a late-stage disease in which the metaplastic activity dwindles. For late stages, the authors suggest a conservative approach that will only provide symptom relief and prevent secondary joint deformity to avoid potential complications and morbidities of a more extensive surgery.
