We report a 22\u2010year\u2010old woman with right preauricular pain, a closed lock, and a maximum unassisted interincisal opening of 19\u2009mm. Cone\u2010beam computed tomography and magnetic resonance imaging confirmed Stage II osteoarthritis of the right temporomandibular joint, right anterior disc displacement without reduction with limited opening, left anterior disc displacement with reduction, and bilateral joint effusion consistent with synovitis. Hormonal testing showed values discordant with the expected follicular\u2010phase ranges after recent discontinuation of injectable contraception; this finding was interpreted as a potential modulatory factor rather than evidence of causation. Management included bilateral temporomandibular joint arthrocentesis, intra\u2010articular administration of betamethasone and sodium hyaluronate, a stabilization splint, pharmacological therapy, physical therapy, and behavioral modification. Pain decreased markedly within the first week. At the 3\u2010month follow\u2010up, maximum unassisted mouth opening was 42\u2009mm, with a straight opening path, pain\u2010free function, and resolution of the right masseter spasm. This case highlights the value of early imaging\u2010based diagnosis and individualized multimodal management in young patients with concomitant mechanical, inflammatory, and early degenerative temporomandibular joint changes.<\/jats:p>","DOI":"10.1155\/crid\/2040786","type":"journal-article","created":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T08:24:53Z","timestamp":1790756693000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Anterior Disc Displacement in a Young Patient With Stage II Osteoarthritis: Diagnostic and Therapeutic Approach.
