Abstract
PURPOSE: Manufacturing a spectacle frame for a facially deformed individual is challenging because of facial asymmetry. One of the solutions is the customization of spectacle frames. Customization of spectacle frames for facially deformed individuals requires a better understanding of the facial anthropometry of deformed faces. This study aimed to analyze the facial anthropometry of deformed faces to understand the range of variability. The results of this study will be used to find customization methods in the future. METHODS: We measured and analyzed the 12 facial parameters of individuals with facial deformities using the ImageJ software. RESULTS: The data collected were normally distributed. Paired sample test revealed a statistically significant difference between innercanthus distances (right innercanthus distance [RICD] and left innercanthus distance [LICD]). Correlation analysis showed a positive difference between horizontal and vertical pupillary distance-innercanthus distance (PD-ICD) (0.68, 0.75, and 0.81) and pupillary distance-helix distance (PD-HD) (0.57, 0.68, and 0.59) relations. PD-ICD correlations are stronger compared to the PD-HD relation. CONCLUSION: Altering the frame center distance and the temple heights are the most important for asymmetric faces. Large population-based data are required to make concrete decisions to design a spectacle frame for asymmetric faces.
