Osteoarthritis of the temporomandibular joint (TMJ) is the end point of long-standing TMJ dysfunction. It is a common finding incidentally on a base of skull imaging, and it should be remembered that TMJ pain does not correlate well with osteoarthritic changes. Indeed pain from TMJ dysfunction is often self-limiting.
Radiographic features
Changes are usually more evident on the condylar side of the joint:
flattening: common (in one series 27%)
osteophytes: common (27%)
erosions: 13%
sclerosis: less common (9%)
subchondral cysts
Treatment and prognosis
Symptomatic treatment usually involves the intra-articular injection of hyaluronic acid, corticosteroids, diclofenac, or glucosamine 4. Injection can be preceded by arthrocentesis (joint lavage). Definitive treatment consists of prosthetic replacement of the joint articular surface 5.
