In inverted nipple, nipple is on a lower plane behind the areola, hiding in a sulcus from which it can usually be pulled out. The inversion presents a functional problem because it interferes with nursing, and a psychological problem because of its abnormal appearance.
  Many operative techniques can be grouped in two, those which only involve a cutaneous repair (and which seem to be less satisfactory), and those which set out to correct the real problem-the shortness of the lactiferous ducts and the fact that they are embedded in shorter, denser, and highly resistant collagen fiber.
  The Elsahy's method used two dermal flaps to add to the bulk of tissues underneath the nipple and to form a sling to prevent recurrence of the inversion. In addition, two similar sized cores of breast tissue under the dermal flaps are sutured together to fill the dead space and hold the nipple forward.
