A\u00a0comprehensive review highlights a\u00a0frequent discrepancy between clinical symptoms and radiologic findings in TMJ arthritis among JIA patients. Key clinical indicators include facial asymmetry, limited mouth opening, and mandibular deviation. We present a\u00a0case of\u00a0a\u00a09-year-old girl with JIA and no reported TMJ symptoms. Clinical assessment revealed facial asymmetry, mandibular deviation, and restricted mandibular mobility. Cone beam computed tomography showed the\u00a0presence of\u00a0unilateral condylar flattening and shortening of\u00a0the\u00a0mandibular ramus. This case underscores the\u00a0importance of\u00a0recognizing facial asymmetry and mandibular hypomobility as potential early indicators of\u00a0TMJ arthritis in children with JIA, even in the\u00a0absence of\u00a0any symptoms or signs. Early detection through attention to subtle morphofunctional signs is imperative for improving patient outcomes in asymptomatic JIA cases.<\/jats:p>","DOI":"10.5114\/reum\/214399","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T06:08:09Z","timestamp":1778479689000},"page":"151-158","source":"Crossref","is-referenced-by-count":0,"title":["Facial asymmetry and mandibular hypomobility as early indicators of\u00a0temporomandibular joint involvement in juvenile idiopathic arthritis"],"prefix":"10.5114","volume":"64","author":[{"given":"Tamara","family":"Pawlaczyk-Kamie\u0144ska","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3061","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"ref-1855959","unstructured":"Martini G, Bacciliero U, Tregnaghi A, et al.
