QUIROS ALVAREZ, P.; GARCIA MARIN, F.; BURGUENO GARCIA, M.  and  VAZQUEZ CARNERO, R.. Synovial chondromatosis of the temporomandibular joint. Rev Esp Cirug Oral y Maxilofac [online]. 2006, vol.28, n.2, pp.100-105. ISSN 2173-9161.

Synovial chondromatosis very rarely affects the TMJ. It is a metaplastic disorder of the synovial tissue that usually produces intra-articular loose bodies, or chondromas. It has variable clinical features and the symptoms are unspecific. Examination by means of magnetic resonance imaging and arthroscopic observation are the diagnostic techniques of choice. Treatment consists in the removal the loose bodies and partial synovectomy. Occasionally the skull has been destroyed and the middle cranial fossa invaded. There are cases of malignant transformation to chondrosarcoma. A long-term follow up is necessary. We describe a case with incipient intracranial extension.

Keywords : Synovial chondromatosis; Intracranial extension; Treatment; Follow-up.
