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.
RESUMO
O objetivo deste trabalho foi comparar o plano de tratamento delineado a partir do diagnóstico obtido através de duas análises cefalométricas distintas, com a decisão clínica tomada para o tratamento cirúrgico de pacientes portadores de maloclusão classe III esquelética. Para isto foram avaliados 82 pacientes classe III esquelética, divididos em três grupos de acordo com o procedimento cirúrgico realizado para a correção da deformidade dentofacial. Suas radiografias cefalométricas pré-operatórias foram submetidas à análise cefalométrica de McNamara e de Steiner. A associação das variáveis foi avaliada pelo teste de correlação de Kappa (α=5%). A concordância entre a indicação do tratamento cirúrgico baseado na decisão clínica e o tratamento cirúrgico proposto a partir da avaliação das análises de McNamara e de Steiner não foi significante (p=0,6094 e p=0,5442,respectivamente). As análises de McNamara e de Steiner apresentaram concordância razoável entre si para o diagnóstico, porém não apresentam concordância com a decisão clínica para o tratamento de pacientes CIII esquelética, sendo as duas análises igualmente imprecisas na indicação do tratamento cirúrgico dos pacientes da amostra.
