Facial photogrammetric measurements as beauty landmarks

Abstract

Introduction: Beauty and attractiveness of a person's facial features are very subjective and also influenced by many factors, such as cultural, social, and personal. It is due to many complex neural mechanisms, that we are able to perceive everything, and also decide if something is attractive or not. The most common and the most significant factors associated with good facial aesthetics are symmetry and proportions of the face. It is important to note that they can be thoroughly analysed using photogrammetry, which represents a non-invasive technique that involves using photographs or 3D imaging methods to capture and analyze the craniofacial structures and features for diagnostic, treatment planning, monitoring and research purposes. When it comes to photogrammetry, angular parameters such as nasofrontal, nasolabial, mentolabial and facial profile angle and linear parameters such as facial width to height ratio, nasal width, interocular and interpupillary distance, philtrum length, chin and forehead height of the face are of great importance. Aim: In this literature survey authors wanted to highlight if these measurements and parameters were enough for determining the beauty and attractiveness of a face if used on their own. Conclusion: Facial photogrammetry has several applications in the field of medicine, particularly in areas such as dermatology, orthodontics, maxillofacial and plastic surgery, due to the usage of angular and linear parameters, as well as other purposes. With many advancements and adjustments, it has become accurate and accessible and has also significantly improved diagnostics, patient care, treatments and outcomes in various cases in medicine and dentistry.
