Dr. David T. Greenspun specializes in the most advanced methods of natural-tissue breast reconstruction. He is a Board Certified Plastic Surgeon practicing in New York City and Greenwich, Connecticut. For women who choose to have natural-tissue breast reconstruction after mastectomy, sophisticated microsurgical techniques make it is possible to reconstruct breasts that restore a natural shape and feel without sacrificing important functional muscles. These procedures, known collectively as perforator flaps, include the DIEP flap, SIEA flap and GAP flap. These same perforator flap techniques of breast reconstruction can also be used to treat patients with other conditions such as Poland's Syndrome and tuberous breast deformity.
