title: Accuracy of two cephalometric analyses in the treatment of patients with skeletal class III malocclusion.
abstract: 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. The association of variables was evaluated by Kappa correlation (α=5%). The agreement between indication of surgical procedures performed based on clinical decision and surgical treatment indicated based on the evaluation of McNamara and Steiner cephalometric analyses were not significant (p=0.609 and p=0.544, respectively). McNamara and Steiner analyses showed reasonable agreement with each other as to the diagnosis, but did not agree with the clinical decision to treat skeletal CIII patients. Both tests were equally inaccurate in the indication of the surgical treatment.
