“…We measured (i) the angle between AAx and MAx and (ii) the shaft curve of the femur (CF) according to AAx (Figure 1), using MicroScribe G2X (Immersion Corp., San Jose, CA, USA) digitizer, the accuracy of the device is confirmed by previous study [19] and the data were obtained by Surfcam Velocity software (Surfware Inc., Camarillo, CA, USA) (Figure 2). …”

Objectives: This study was designed (i) to evaluate the angle between anatomical and mechanical axes of the femur and (ii) to compare shaft curve of the femur according to anatomical axis of femur with curve of the four femoral nail used in a Turkish population, in order to determine the safety degrees of distal femoral valgus cut for a routine surgical procedures. Methods:Sixty-six right femurs, 68 left femurs and 4 femoral nails were measured. We measured the angle between anatomical axis and mechanical axis, the shaft curve of the femur according to anatomical axis on the femurs and shaft curve of the femoral nail on 4 femoral nails, which are commonly used in Turkey, using a digitizer system. Results:In the 66 right femurs, the mean values of the angle between anatomical axis and mechanical axis was calculated as 6.386±0.820º and the mean value of the shaft curve of the femur according to anatomical axis was calculated as 16.713±2.371º. In the 68 left femurs, the mean value of angle between anatomical axis and mechanical axis was calculated as 6.915±0.712º and the mean value of the shaft curve of the femur according to anatomical axis was calculated as 16.148±2.689º. We calculated that curve of the 4 nails were Hipokrat 8.65º, Trigen 10.20º, Ortopro 6.38º and Recon 8.70º, respectively. Conclusion:According to our results, new nails should be designed in the light of anatomical studies for each population. This will reduce the complications during surgery.

“…Biologically meaningful landmarks are the basis of face recognition and analysis [48], and were also previously used for symmetry analysis [1,5,14]. Recent investigations assessed the performance of contact instruments in clinical practice, and found their usage satisfactory, also considering that these instruments can be used directly in any environment, for instance quickly meeting the attractive subjects during beauty competitions, fashion events, or castings [30][31]49]. In contrast, optical instruments (laser scans, stereophotogrammetric digitizers) usually need dedicated locations, which often cannot be organized outside specialized laboratories.…”

Three-Dimensional Facial Asymmetry in Attractive and Normal People from Childhood to Young Adulthood

Abstract:We are currently investigating measurable esthetic characteristics in persons considered "attractive" by the media. Three-dimensional soft-tissue facial asymmetry was quantified in 380 attractive (148 males, 232 females) and 669 control (397 males, 272 females) healthy persons aged 4-30 years. The coordinates of 50 facial landmarks were collected by a computerized digitizer, and asymmetry computed. Soft-tissue facial asymmetries reduced as a function of age in all cases. Attractive children were more symmetric than control children, but the reverse was true for young adults. The effect of symmetry on attractiveness seems to change as a function of age.

“…The facial landmarks are digitized one by one using a stylus connected to the digitizer. 2,4,7 Ultrasound probes use acoustic waves in the Megahertz frequency domain, while electromagnetic and electromechanic digitizers are based on electromagnetic waves. The main limitations of the instruments are the reduction of information obtained, and the data acquisition time, which is extremely long when compared to optical methods.…”

“…Together with these classic measurements, mathematics and geometrics allow the assessment of more complex characteristics from the same set of landmarks used by conventional anthropometry: estimations of volumes and surfaces, analyses of symmetry, and detailed assessments of shape.

Facial anthropometry plays a key role in clinical assessments, providing an accurate diagnosis for different syndromes. Clinicians working with the head and face (maxillo-facial, plastic and aesthetic surgeons; orthodontists and prosthodontists) are the mostly interested in this three-dimensional information, being able to estimate the normal and abnormal growth, planning and evaluating surgical or orthodontic treatment, plastic surgeries and anthropometric studies.
