Macrognathia of renal osteodystrophy in dialysis patients

A multiinstitutional study of macrognathia secondary to renal osteodystrophy in dialysis patients is presented. The nine cases reviewed reveal a variety of radiographic and histopathologic features, some of which resemble fibrous dysplasia and others suggestive of Paget's disease of bone. This article contains diagnostic criteria for differentiating renal osteodystrophy from similar fibro-osseous proliferations along with a discussion of the underlying cause and appropriate therapeutic interventions.
