The inferior pedicle (central mound) features a blood vessel supply (arterial and venous) for the NAC from an inferior, centrally-based attachment to the chest wall.[21] The skin pedicle maintains the innervation and vascular viability of the NAC, which produces a reduced, sensitive breast with full lactational capability and function.[22] The volume and size reduction of hypertrophied breasts is performed with a periareolar incision to the NAC, which then extends downwards, following the natural curve of the breast hemisphere. After cutting and removing the requisite quantities of tissue (glandular, adipose, skin), the NAC is transposed higher upon the breast hemisphere; thereby the inferior pedicle technique produces an elevated bust with breasts that are proportionate to the woman's person. Nonetheless, breast-reduction with an inferior pedicle, occasionally produces breasts that appear squared; yet, the technique effectively reduces the very enlarged breasts of macromastia and gigantomastia.[citation needed]
