The aim of this study was to validate the experts' clinical diagnosis test (ECDT) as a way of measuring the facial vertical excess (VFE).
After principal factor analysis, ECDT included, finally, six variables: Facial profile, Anterior lower face height, Size of the body and mandibular ramus, gonial angle, and menton position.
This last subjects were classified as without VFE when Receiver Operative Characteristics of ECDT was made.
Principal factor analysis (varimax rotation) was used to build ECDT. Internal consistency was evaluated with Cronbach's alpha coefficient.
ECDT was clinically and statistically different in patients qualified through QA-VFE in both, first and second evaluation (Table 3).
The ECDT is represented by six of nine clinical variables used to facial evaluation, and has the ability to discriminate patients with severe VFE.
Additionally, it will allows the use of the ECDT as a gold standard in sagital malocclusions, comparing to previous studies or evaluating the need and reproducibility of new cephalometric analysis (18).
Within this study, the experts considered that the ECDT could be used as a gold standard for vertical facial excess.
