Male breast enlargement is often a combination of both extra fat and extra breast tissue (referred to as gynecomastia), and sometimes extra skin as well (as in the case of patients who have had massive weight loss). Techniques such as Coolsculpting or liposuction will address any fat that's causing the breast enlargement, but they won't address gynecomastia tissue or excess skin. Depending upon a patients anatomy, Coolsculpting may be a reasonable option, although an evaluation by a plastic surgeon knowledgeable about surgical management of gynecomastia or excess skin will be best to understand all the potential options. In order to get a qualified, ethical, and expert opinion on your surgical options and expectations, schedule an in-person office consultation with a plastic surgeon certified by the American Board of Plastic Surgery.
