The use of 3D technology has become important in the practice of surgeons, due to the limitations of 2D photographs. This is a prospective, analytical, and comparative study, which aims to analyze in a comparative way the three-dimensional reconstruction of two different systems, through computed tomography of the face and the respective stereophotogrammetry acquired from the same face. It was possible to reconstruct a total of 25 meshes from participants who underwent facial tomography and photogrammetry at the IPO Hospital. The study aims to describe the computerized technique of three-dimensional reconstruction of the face and mainly to evaluate the equivalence of the surface of the face obtained by two different techniques that propose the analysis of the anatomy. The first mesh was obtained by computed tomography. The second by the stereophotogrammetry technique, with capture performed by the clOner scanner and with the reconstruction of the mesh in the Reality Capture application. In addition, to demonstrate a three-dimensional facial evaluation system without ionizing radiation, low cost, and high availability. The results obtained were sufficient to demonstrate the equivalence between the meshes. Thus, stereophotogrammetry of the face is a new option for anatomical analysis of the face. It does not cause discomfort or risks to the patient and increases the possibilities of analysis.
