O objetivo deste estudo foi demonstrar a precisão e a acurácia de medidas maxilofaciais lineares e angulares obtidas por tomografia computadorizada por feixe cônico (TCFC). A amostra consistiu de quinze crânios humanos secos submetidos à TCFC. Medidas lineares e angulares foram realizadas em imagens em terceira dimensão (3D) após a identificação de pontos craniométricos convencionais. As imagens em 3D-TCFC foram analisadas por dois radiologistas, duas vezes, independentemente. Medidas físicas foram realizadas por um terceiro examinador utilizando paquímetro e goniômetro digitais. Os resultados não demonstraram diferenças estatísticas significantes para as análises intra e interexaminadores. As comparações entre as medidas físicas e as obtidas em 3D-TCFC para ambos os examinadores também não foram estatisticamente significantes tanto para as medidas lineares quanto paras as angulares (p= 0,968 e 0,915, p= 0,844 e 0,700, respectivamente). As imagens em 3D-TCFC podem ser utilizadas com precisão e acurácia para a obtenção de medidas lineares e angulares a partir de estruturas anatômicas e pontos craniométricos. / The purpose of this research was to provide further evidence to demonstrate the precision and accuracy of maxillofacial linear and angular measurements obtained by cone-beam computed tomography (CBCT) images. The study population consisted of 15 dry human skulls that were submitted to a CBCT, and threedimensional (3D) images were generated. Linear and angular measurements based upon conventional craniometric anatomical landmarks, were identified in 3D-CBCT images by two radiologists twice each independently. Subsequently physical measurements were made by a third examiner using a digital caliper and a digital goniometer. The results demonstrated no statistically significant difference between inter and intra-examiner analysis. Regarding accuracy test, no statistically significant difference were found of the comparison between the physical and CBCT-based linear and angular for both examiners (p= 0.968 and 0.915, p= 0.844 and 0.700 respectively). 3D-CBCT images can be used to obtain dimensionally accurate linear and angular measurements from bony maxillofacial structures and landmarks.
