Surgical approach and clinical outcome of a deforming brown tumor at the maxilla in a patient with secondary hyperparathyroidism due to chronic renal failure.

Brown tumors are relatively uncommon but they are serious complications of renal osteodystrophy. We describe a 31-year-old woman with end-stage renal disease who had undergone hemodialysis for nine years and developed severe secondary hyperparathyroidism and a maxilla brown tumor despite increasing doses of oral calcitriol and calcium carbonate. The fast increase of the right maxillary bone tumor led to indication of parathyroidectomy (PTx).

Comparison of mandibular rami width in patients with prognathism and retrognathia.

Purpose: The purpose of this study was to assess the ramus thickness in skeletal Class III and Class II patients.

Methods: Forty patients were evaluated using computed tomography scanning.

Results: Compared with the Class II patients, the mandibular ramus of Class III patients was thinner.
