Inframammary Incision Planning in Breast Augmentation: A Patient- and Implant-Specific Pythagorean Method.

Area of Science:

• Plastic Surgery
• Biomechanical Engineering
• Medical Geometry

Background:

• Optimal inframammary incision placement is crucial for aesthetic breast augmentation outcomes.
• Minimizing visible scarring is a key consideration in breast augmentation surgery.
• Current methods for determining incision location lack standardization.

Purpose of the Study:

• To present a modified geometric model for determining nipple-to-inframammary fold (IMF) distance.
• To establish an objective method for planning inframammary incision placement.
• To improve aesthetic predictability and scar concealment in breast augmentation.

Main Methods:

• A modified geometric model based on the Pythagorean theorem was developed.
• The model integrates anatomical variables like breast tissue thickness.
• Implant characteristics, including gel cohesiveness, were incorporated into the model.

Main Results:

• The model offers a reproducible and individualized strategy for incision planning.
• Placement strategies are adjusted based on implant cohesiveness for optimal results.
• Soft cohesive implants require higher initial placement; firmer gels are placed lower.

Conclusions:

• This geometric approach standardizes inframammary incision placement.
• The model combines geometry, clinical anatomy, and implant biomechanics.
• This method enhances aesthetic predictability and scar concealment in breast augmentation.
