Linear Regression Algorithm for Male Nipple-Areolar Complex Anthropometry and Placement, Using Body Mass Index

Area of Science:

• Plastic Surgery
• Anthropometry
• Male Aesthetics

Background:

• The nipple-areolar complex (NAC) holds significant aesthetic and functional importance.
• Established methodologies for male NAC placement are lacking.
• This research addresses the need for normative data in the male Mexican population.

Purpose of the Study:

• To determine normal NAC measurements in the male Mexican population.
• To investigate the association between NAC anthropometry, body mass index (BMI), and age.
• To develop a linear regression model for preoperative NAC planning and placement.

Main Methods:

• Anthropometric measurements of the NAC were conducted on 385 adult males in the State of Mexico.
• Descriptive statistics and Spearman correlation tests were employed.
• A linear regression model was generated to predict NAC measurements based on age and BMI.

Main Results:

• Body mass index (BMI) demonstrated a strong correlation with NAC anthropometry, independent of age.
• The average NAC diameter was found to be 2.25 cm.
• NAC diameter was independent of both BMI and age.

Conclusions:

• The study provides essential anthropometric values for the male Mexican population.
• A validated linear regression equation is presented for preoperative planning of NAC placement.
• The developed model is applicable across a broad range of BMI and age values.
