RESUMO
OBJECTIVES: Using a clinical survey, panoramic, cone-beam computed tomography (CBCT), and magnetic resonance (MR) imaging, this study was conducted to ascertain primary maxillofacial abnormalities in patients with mucopolysaccharidosis VI (MPS VI). STUDY DESIGN: Two patients previously diagnosed with MPS VI underwent clinical and imaging surveys (panoramic radiographs, CBCT, and MR imaging). RESULTS: Jaw involvement was present in all patients. The most prevalent findings were enlarged marrow spaces, osteopenia, dentigerous cyst-like follicles, effacement of the jaw structures, and osteosclerosis. This is the first study to describe temporomandibular joint (TMJ) involvement for MPS VI. CONCLUSIONS: CBCT and MR imaging were needed to observe features that were not clear in conventional radiographs. Both patients reported symptoms in the TMJ and demonstrated involvement during their examinations. A multicenter study is necessary to better document maxillofacial involvement in MPS VI.
