Osteoarthritis is a type of articular origin Temporomandibular disorders, being one of the most common degenerative processes affecting the temporomandibular joint. It is characterized by remodeling of the underlying subchondral bone, deterioration and abrasion of articular tissue. Intra-arti- cular injections of hyaluronic acid are considered beneficial for treatment of pain and recovery of joint tissues properties. The aim of this article is to describe the use of hyaluronic acid in the management of osteoarthritis of temporomandibular joint in an adolescent patient. Female patient, 15 years old, presented pain with a year of progress in the bilateral preauricular region, with increased pain at maximum aperture. Considering the clinical and imaging tests the patient was diagnosed with disk displacement with reduction with bilateral osteoarthritic and inflammatory component. Mandibular rest, liquid diet, NSAIDs were indicated and the application of intra-articular hyaluronic acid (Suprahyala 25 mg / 2.5 ml) bilaterally. Control was quoted at 2, 3 and 16 weeks where the patient has no spontaneous pain and tenderness. The use of hyaluronic acid is one of the most commonly used therapeutic alternatives for the management of osteoarthritis of temporomandibular joint. However, further evidence of its use in intra-articular application in adolescents and children should be incorporated.
