Accuracy of two cephalometric analyses in the treatment of patients with skeletal class III malocclusion.

The aim of the present study was to compare the treatment plan outlined from the diagnosis obtained by two different cephalometric analyses with the clinical decision made for surgical treatment of patients with skeletal Class III malocclusion. For this purpose, 82 skeletal Class III patients were evaluated, divided into three groups according to the surgical procedure performed for dentofacial deformity correction. Their preoperative cephalometric radiographs were submitted to McNamara and Steiner cephalometric analyses.
