Population analysis of the perfect breast: a morphometric analysis

Area of Science:

• Plastic Surgery
• Aesthetic Medicine
• Human Anatomy

Background:

• Previous research identified objective parameters for the aesthetic ideal of natural breasts.
• This study surveyed public opinion on ideal breast proportions.

Purpose of the Study:

• To determine the general public's preferred breast proportions.
• To validate previous findings on ideal breast aesthetics.
• To establish a guideline for aesthetic breast surgery.

Main Methods:

• 1,315 respondents ranked images of breasts with varying upper-to-lower pole ratios (35:65, 45:55, 50:50, 55:45).
• Demographic factors including age, sex, nationality, and ethnicity were analyzed.
• The opinions of 53 plastic surgeons were incorporated.

Main Results:

• A 45:55 upper pole-to-lower pole ratio was universally preferred.
• This ratio was highly favored across diverse demographics, including men, women (especially those in their thirties), and plastic surgeons.
• Specific high agreement percentages were noted for men (90%), plastic surgeons (94%), North Americans (92%), South Americans (95%), Caucasians (87%), and Asians (87%).

Conclusions:

• The 45:55 ratio is reaffirmed as having universal appeal for ideal breast aesthetics.
• This proportion is proposed as a standard for aesthetic breast surgery design.
• Consistent aesthetic preferences suggest a biological or cultural basis for the ideal breast shape.
