Synovial
chondromatosis of the temporomandibular joint.
Med Oral Patol Oral Cir Bucal. 2007 Jan 1;12(1):E26-9.
Synovial
Chondromatosis (SC) is a disease whose etiology is unknown, can be
defined as a benign synovial process characterized by the formation of
metaplastic cartilaginous nodes inside connective tissue of articular
surfaces, is considered an active metaplastic phenomenon better than a
neoplastic process; it presents a greater preference to affect women
who constitute almost 70% of reported cases, the age range is wide and
oscillates between 18-75 years (average 44.6 years). Between the main
clinical findings are: pain, crackle, volume augmentation and a
limited buccal opening. SC is an unusual state and the reports in the
English literature are no more than 75 cases, only 66 of those where
histologically verified, most of those were affecting great joints
like hip, knee and shoulder, but if SC is not frequent in this sites,
is even more infrequent on temporomandibular joint. The aim of this
paper is to report a clinical case and at the same time to realize a
brief review of the literature.

Craniofac Surg. 2007 Nov;18(6):1486-8.
Synovial
chondromatosis is a cartilaginous metaplasia of the mesenchymal
remnants of the synovial tissue of the joints. Its main
characteristic is the formation of cartilaginous nodules in the
synovium and inside the articular space (loose bodies). Synovial
chondromatosis mainly affects big synovial joints such as the elbow
and knee and is uncommon in the temporomandibular joint. The main
symptoms are pain, limitation of jaw movement, crepitation, and
inflammation. Diagnosis is made by panoramic radiograph, computed
tomography scan, and mainly magnetic resonance imaging. Surgery is
the therapeutic choice. The authors describe their experience in the
treatment and in the follow up of a patient with unilateral synovial
chondromatosis.
Arthrocentesis in the treatment of loose bodies of the
temporomandibular joint associated with synovial chondromatosis.Br
J Oral Maxillofac Surg. 2007 Oct 6.
Synovial
chondromatosis is a benign disorder of joints of unknown aetiology,
characterised by the presence of loose bodies in the articular space.
We present a case that affected the temporomandibular joint (TMJ) and
was treated with arthrocentesis, which is an efficient, conservative,
and inexpensive treatment.
Synovial chondromatosis of the temporomandibular joint with middle
cranial fossa extension.
Int J Oral Maxillofac Surg. 2007 Jul;36(7):652-5. Epub 2007 Mar
26.
Synovial
chondromatosis of the temporomandibular joint (TMJ) is relatively
rare. An unusual case with extension through the glenoid fossa and
into the middle cranial fossa is reported. Invasion of the
infratemporal fossa and the middle cranial fossa was seen on both
computed tomography and magnetic resonance imaging. Complete removal
of the loose bodies with excision of the affected synovium is the
accepted treatment of synovial chondromatosis. A conservative approach
should be followed while trying to eliminate any remaining lesion in
the infratemporal fossa and the middle cranial fossa. An overview of
previously reported cases of synovial chondromatosis with cranial
extensions is also presented.
