Photogrammetric Analysis of Facial Soft Tissue from Profile View of Patients Referred to Imam Reza Hospital in Ardabil for Analysis of Facial Plastic Surgeries(Original Article)

Background: Photogrammetric analysis of facial soft tissue plays an important role in facial plastic surgeries. In many countries, planning for facial plastic surgery is done based on the defined facial metric standards for the same society. Few research works have been conducted in the field of facial cephalometric criteria of the Iranian race. The main goal of this study is to determine the average values of facial profile view metrics of people referred to Imam Reza Hospital (Ardabil). Methods: First, in a period of 3 months, facial profile view images of the referred patients including 30 males and 30 females were provided. Then, the angular criteria of the profile view were measured by selecting 11 facial anatomical landmarks applicable for Rhinoplasty and Mentoplasty surgeries in the MATLAB software. Results: The results showed that among the facial profile view metrics, the Nasofrontal, Nose Tip and Mentolabial angles are close to the criteria of the Turkish, Nepalese and Brazilian races, respectively. The Facial Convexity Including Nose (FCIN) metric is close to the Brazilian and Nepalese races, and also, Facial Convexity Excluding Nose (FCEN) is close to the Bangladesh and Brazilian races. Conclusion: In this study, cephalometric analysis of facial soft tissue was done by measuring the facial profile view metrics to help facial plastic surgeons. Considering the difference in facial metrics of Iranians with other races, the criteria measured in this study can be interesting for surgeons in planning of facial cosmetic surgeries, especially Rhinoplasty and Mentoplasty
