Anthroposcopy means judging the body’s built by inspection. Visual assessment, one of the oldest methods of examination, still used in medicine today, is not reliable because is highly subjective. Anthropometric studies are therefore needed for quantitative assessment. Traditional methods use an assortment of instruments (goniometers, rulers and tapes), which can cause varying measurement errors, depending on the region of interest and the examiner’s experience and consequently may produce conflicting results, making the worth of scientific information doubtful. In this paper we discuss the use of photogrammetric techniques for craniofacial studies, explaining how this technique can be implemented and what are the comparative advantages to the commonly used methods that are still favored by the majority of medical doctors. Photogrammetry not only can minimize the above sources of errors, but it can also assist the doctor to perform and repeat the measurements in later time periods from that of the time of acquisition. We investigated 102 dissected facial halves and we used pins as markers of anatomic facial details in order to determine the Modiolus area relative to other stable, anatomic, osteal craniometrical points and measure details of the Zygomaticus Major muscle. The image acquisition and the photogrammetric processing including camera calibration, using a low cost software that supports maximum ease of use, are analyzed and results from the quantitative assessment are presented. Moreover, the paper demonstrates the feasibility that non-experts in photogrammetry can use commercial cameras and simple photogrammetric software tools to derive the required information.
