Abstract
We describe here the temporomandibular joint and masticatory muscle abnormalities
disclosed by computed tomography and magnetic resonance imaging in a 25-year-old man
with centronuclear myopathy (a congenital myopathy) who presented with marked limitation
of jaw movements. We found an intense and general fatty replacement of the masticatory
muscles, and magnetic resonance imaging signals indicated articular fibrosis. We conclude
that in centronuclear myopathy, the presence of weakness and hypomotility of the masticatory
muscles can induce chronic abnormalities of the temporomandibular joint. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2000;90:118-21)
