Summary
Women with ideal buttocks have a narrower waist and hips but a wider C point and larger gluteus maximus muscle (GMM) compared to women with normal buttocks. This GMM size contributes to buttock projection.
Area of Science:
- Plastic Surgery
- Anatomy
- Aesthetics
Background:
- Understanding the anatomical differences between aesthetically ideal and normal buttocks is crucial for surgical planning.
- Previous studies have focused on specific measurements, but a comprehensive 3D analysis is lacking.
Purpose of the Study:
- To delineate the anatomical characteristics of women with aesthetically ideal buttocks.
- To differentiate these characteristics from those of women with normal buttocks.
Main Methods:
- A case-control study was conducted.
- Participants were categorized into 'buttocks models' (ideal) and 'normal' groups.
- Magnetic resonance imaging, anthropometric measurements, and photography were utilized for anatomical comparison.
Main Results:
- Buttocks models exhibited a narrower waist and iliac crest compared to controls.
- Models had a wider C point and hips.
- A larger and thicker gluteus maximus muscle (GMM) was observed in models, contributing to increased C point projection.
Conclusions:
- Aesthetically ideal buttocks result from a combination of bone structure, gluteus maximus muscle development, and subcutaneous fat.
- Key differentiating features include a narrower waist/iliac crest, wider C point/hips, and a more developed GMM.
- This detailed anatomical understanding can refine surgical techniques for buttock augmentation.
