What is the dual plane technique?

The dual plane technique positions a breast implant in two anatomical layers during augmentation surgery. The upper half of the implant sits beneath the pectoral major muscle, while the lower half rests under the breast tissue directly. This partial muscle coverage creates a transition zone that combines structural support with natural breast contour.

Surgeons choose dual plane placement to address specific aesthetic and functional goals. The muscle coverage in the upper breast provides support for the implant and helps prevent rippling that can occur with tissue-only placement. At the same time, the lower portion's positioning under breast tissue alone allows for a more natural lower pole projection and fullness, particularly important for patients with minimal natural breast volume.

The technique works best for patients who want defined upper breast shape without the flattened appearance sometimes associated with full submuscular placement. It also reduces animation deformities (visible muscle movement during chest exercises). Placement decisions depend on factors including existing breast tissue, skin thickness, and body frame. Ontario surgeons performing breast augmentation evaluate each patient's anatomy to determine whether dual plane, submuscular, or subglandular placement aligns with their goals.
