Multiplanar Assembly Mammaplasty Based on the Divine Proportion.

Background: The study sought to plan mastopexy and breast reduction according to the principle of the divine proportion, represented by the letter phi, via the convergent assembly of multiple layers to create the new breast. This strategy is based on the constancy of the submammary fold and the orientation of the vertex of a V-shaped triangle opening at approximately 60° at the umbilicus, with each branch opening in the direction of the acromioclavicular joint.

Methods: The strategy was prospectively investigated in 265 patients (n = 530 breasts).
