About this study
The main objective of this research is to identify the focal length that allows the most accurate and reproducible 2D assessment of facial aesthetics, without introducing significant distortion. Ultimately, this will enable the establishment of a standardized photography protocol for maxillofacial and aesthetic surgery, facilitating harmonized pre- and post-operative assessments and improving communication between healthcare providers and patients.
Read the detailed description
Facial aesthetics are a central concern in both reconstructive and aesthetic surgery. Photography has become an essential tool for documenting, comparing, and evaluating facial outcomes before and after surgical procedures. However, variations in camera settings-particularly focal length-can significantly influence the perceived proportions of the face, potentially leading to misinterpretation or distortion in aesthetic assessment.
This project seeks to address this issue by developing a standardized photographic protocol for facial aesthetic evaluation. Specifically, it aims to identify the optimal photographic parameters, with a focus on focal length, that produce the most accurate and consistent two-dimensional (2D) representations of the face. It is well known that different focal lengths affect the visual perception of depth and facial proportions, making the subject appear more or less harmonious or attractive depending on the configuration.
To do this, a collection of facial images will be created using different focal length settings, while keeping other shooting conditions constant (subject-camera distance, lighting, background, and subject posture).

What is being measured
The primary outcome is the main question the study is designed to answer.
Identify the focal length setting for optimal assessment of facial aesthetics on 2D photographs
Attractiveness score from 1 to 5 (from very unattractive to very attractive, respectively). The images will be evaluated by 4 independent raters (2 experts: facial surgeons, and 2 non-experts) based on the focal length used: 50 mm, 85 mm, 105 mm, 135 mm, and 200 mm.
Measured: Up to 3 months
