“…It is a simple, fast and accurate method which captures the face shape and texture in 3D 1,[14][15][16][17] . Recently, several studies have adopted similar approaches in building their 3D facial models as they implemented stereophotogrammetry and computed tomography concepts 8 .…”

“…The image-assisted presurgical assessment and planning, including three dimensional volumetric data, surface topography and reconstruction of the defects using the mirror image, improves success of surgery. 18,19 Therefore, advanced imaging modalities could play a more important role in the pre-and post-treatment evaluation of patients undergoing anti-ageing procedures of the face. Since the appearance of the face is one of the most important measures for the evaluation of facial ageing, many studies have attempted to use qualitative measures to evaluate the progression of facial ageing and the response to rejuvenation treatments via the use of facial photographs as a primary assessment tool.…”

Objectives: To investigate the location-specific tissue properties and age-related changes of the facial fat and facial muscles using quantitative MRI (qMRI) analysis of longitudinal magnetization (T1) and transverse magnetization (T2) values. Methods: 38 subjects (20 males and 18 females, 0.5-87 years old) were imaged with a mixed turbo-spin echo sequence at 1.5 T. T1 and T2 measurements were obtained within regions of interest in six facial fat regions including the buccal fat and subcutaneous cheek fat, four eyelid fat regions (lateral upper, medial upper, lateral lower and medial lower) and five facial muscles including the orbicularis oculi, orbicularis oris, buccinator, zygomaticus major and masseter muscles bilaterally. Results: Within the zygomaticus major muscle, age-associated T1 decreases in females and T1 increases in males were observed in later life with an increase in T2 values with age. The orbicularis oculi muscles showed lower T1 and higher T2 values compared to the masseter, orbicularis oris and buccinator muscles, which demonstrated small age-related changes. The dramatic age-related changes were also observed in the eyelid fat regions, particularly within the lower eyelid fat; negative correlations with age in T1 values (p , 0.0001 for age) and prominent positive correlation in T2 values in male subjects (p , 0.0001 for male 3 age). Age-related changes were not observed in T2 values within the subcutaneous cheek fat. Conclusions: This study demonstrates proof of concept using T1 and T2 values to assess agerelated changes of the facial soft tissues, demonstrating tissue-specific qMRI measurements and non-uniform ageing patterns within different regions of facial soft tissues.

The investigations into the mechanisms of facial ageing have revealed a multifactorial process involving a combination of structures with functional and structural changes including loss of elasticity, facial fat atrophy, weakened muscular support and bony Correspondence to: Dr Memi Watanabe.

“…Within medicine, 3D photography is gaining acceptance as a useful clinical tool. Published reports in facial plastic surgery [4], maxillofacial surgery [5], and breast surgery/reconstruction [6,7] have all endorsed 3D photography for its ability to reliably and precisely detect changes in 3D shape and volume and to objectively assess and quantify surgical outcomes. 3D software allows volume, distance, and circumference measurements to be taken at any location along the 3D image, and sequential 3D images can be aligned to ensure reproducibility between measurements at different time points.…”
