pocket dissection

Full Definition

The surgical technique of creating an appropriately sized anatomical space or 'pocket' to house a breast implant or tissue expander during reconstructive surgery. Pocket dissection involves careful separation of tissue planes, typically between the pectoralis major muscle and chest wall for subpectoral placement, or between the muscle and breast tissue for prepectoral placement. Proper pocket creation is crucial for optimal implant positioning, symmetry, and long-term aesthetic outcomes.

Usage

Usage note: Distinguish from capsulotomy (cutting existing scar tissue) and pocket revision (modifying existing pocket).
