Comparison of the Cosmetic Results, Quality of Life and Patient Satisfaction Achieved With Round-block and Retroglandular Oncoplastic Breast Conserving Surgeries

We de-epithelize the gap between the double round-lines, and we dissect the dermis from the best localization where we can reach the tumor. If the tumor located close to the skin then we are not performing de-epithelization, we excise it with the skin. We mark every wall of the tumor bed with clips. We dissect the surrounding parenchyma- so called parenchyma pillars- from the pectoral fascia and the skin, and we mobilize it. The line under the skin means, the layer under the subcutis, above the superficial fascia, so gives appropriate blood supply to the skin. After this the incision line should be placed 5 mm from the outer round line, so a dermis pillar should be left, and the skin is dissected from the parenchyma as needed. The outer round line should be tightened with a non-absorbable running Benelli suture to fit the areola then interrupted sutures placed to make tensionless the running intracutaneous suture.

We incise the skin slightly lateral in the IMF, around 7 cm long. We dissect with electrocauther the parenchyma with the pectoral fascia from the pectoralis major muscle at least until the mamilla. We incise the fascia along with the parenchyma which contains the tumor and macroscopically 10 mm safe zone. If the tumor is palpable, we turn the parenchyma slightly inside-out, if not, we localize it at the maximum measurement detected according to the ROLL labeling. After marking the tumor bed, we directly adapt the surrounding parenchyma pillars with absorbable sutures, or inverting sutures, or if it requires, we adapt the tumor bed with so-called dual plane mobilization. After revision, we close the fascia with absorbable running suture over the Redon drain then subcutaneous running suture with absorbable suture and finally intracutaneous skin closure.
