Breast-Volume Displacement Using an Extended Glandular Flap for Small Dense Breasts

We defined the glandular flap including fat in the subclavicular area as an extended glandular flap, which has been used for breast-conserving reconstruction in the upper portion of the breast. Indication. The excision volume was 20% to 40% of the breast volume, and the breast density was dense. Surgical Technique. The upper edge of the breast at the subclavicular area was drawn in the standing position before surgery. After partial mastectomy, an extended glandular flap was made by freeing the breast from both the skin and the pectoralis fascia up to the preoperative marking in the subclavicular area. It is important to keep the perforators of the internal mammary artery and/or the branches of the lateral thoracic artery intact while making the flap. Results. Seventeen patients underwent remodeling using an extended glandular flap. The cosmetic results at 1 year after the operation: excellent in 11, good in 1, fair in 3, and poor in 2. All cases of unacceptable outcome except one were cases with complications, and more than 30% resection of moderate or large size breasts did not obtain an excellent result for long-term followup. Conclusion. This technique is useful for performing the breast-conserving reconstruction of small dense breasts.

Oncoplastic Technique Combining an Adipofascial Flap with an Extended Glandular Flap for the Breast-Conserving Reconstruction of Small Dense Breasts

We introduce a method combining two oncoplastic techniques for breast-conserving reconstruction. The procedure is as follows: first, an extended glandular flap is made by undermining the breast from both the skin and the pectoralis fascia to the upper edge of the breast at the subclavicular area. After modeling the breast mound with the extended glandular flap, an inframammary adipofascial flap is made. The flap is reflected back to the breast area remodeled using the extended glandular flap. After reshaping the breast, the inframammary line is then re-shaped. This method is indicated for patients with breast cancer in the outer portion of the breast, who have small dense breasts, and have undergone a large excision of about 40% of their breast volume. We treated four patients, all of whom had either excellent or good cosmetic results with no fat necrosis.

Abdominal advancement flap as oncoplastic breast conservation: report of seven cases and their cosmetic results.

An abdominal advancement flap (AAF) is a flap that pulls the elevated abdominal skin up and creates the shape of the inferior portion of the breast by making a neo-inframammary fold. Seven patients underwent remodeling using an AAF or a method combining an AAF with other volume displacement techniques after partial mastectomy. The excision volume ranged from 15% to 35%. AAF with only mobilization of the gland flaps was performed in two cases, with lateral mammoplasty in one case, with the round block technique (RBT) in one case, with a modified RBT in one case, and with medial mammoplasty in two cases. Although one patient treated with a RBT had a partial blood-flow insufficiency of the nipple-areola complex, it improved with conservative treatment. The cosmetic results were found to be excellent in three cases, good in three, and fair in one case.
