Procedure: Immediate breast reconstruction following bilateral mastectomy. Two stage procedure with expanders (1st stage) and breast implants (2nd stage).
Outcome: This patient had a bilateral mastectomy for a triple negative breast cancer and was immediately reconstructed with Mentor 350cc tissue expanders placed under the muscle and an acellular dermal matrix (FlexHD). Her second stage procedure involved exchanging her expanders for definitive breast implants. Her expanders were initially sitting high and apart. I tell my patients to expect that the expander will often ride high and feel irregular, but at the time of the 2nd stage exchange I can manipulate the pocket to correct any malposition. In the 2nd stage, I corrected the implant pocket, especially to fill out the medial inferior pole of the left breast. The patient was upsized to Motiva 450cc ergonomix full profile implants. This is her result 4 weeks after the second stage procedure showing a lift and increase in her breast volume. Her breasts are sitting close together offering an excellent contour and shape. The implants are also a lot more comfortable than the expanders.
