Osteoarthritis of the temporomandibular joint

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.
