SANCHEZ T., Marco    BECERRA B., Walter. Temporomandibular joint osteoarthritis (arthrosis). Rev. Otorrinolaringol. Cir. Cabeza Cuello []. 2020, 80, 4, pp.540-553. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162020000400540.

Osteoarthritis of the temporomandibular joint (TMJ) is a degenerative disorder of multifactorial etiology, which requires interdisciplinary management. It occurs between 8% to 16% of the population and is associated with excess joint load, trauma, genetic factors, parafunctions and internal disorders of the joint, a high frequency of reflex otalgia and tinnitus is also recognized in patients with degenerative TMJ disorder. The combined use of computed tomography and magnetic resonance allows to observe the morphological variations in the hard and soft tissues of the joint structure. Non-invasive treatment includes the indication of mandibular repositioning splints, in addition to the use of anti-inflammatory drugs and preference for selective cyclooxygenase-2 inhibitors (COX-2). Intra-articular injection of corticosteroids reduces inflammation of the articular tissues and improves mobility in the long term, while hyaluronic acid seems to decrease friction in the articular spaces. Surgical procedures such as arthroscopy, condylectomy, arthroplasty, autogenous disc replacement, or total joint replacement should be reserved for cases where non-invasive intervention shows no clinical improvement.
