It uses the principle
of tissue expansion, achieved in this case through long term suction to stretch the lactiferous ducts.
«Surgeons use a variety of techniques to grow skin
for tissue expansion procedures designed to grow skin in one region of the body so that it can be auto - grafted on to another site [sometimes used for burn victims],» said Guy German, assistant professor of biomedical engineering within the Thomas J. Watson School of Engineering and Applied Science at Binghamton University.
During postnatal growth of the skin and homeostatic hair cycling, different proliferative compartments contribute to
tissue expansion and establishment of a functional epidermis.
The surgical treatment options include simple excision and re-suturing (single or multi-stage),
tissue expansion and excision, fat transfer for contour deformities, free tissue transfer etc..
