1. | Free flap for immediate breast reconstruction as part of ablative surgery (modified radical mastectomy, SSM, NSM) |
2. | Free flap for repair of chest wall defects |
3. | Free flap for delayed breast reconstruction after ablative surgery |
4. | Free flap for conversion to autologous reconstruction in prosthesis-related complications |
B. Breast-conserving surgical procedures | |
1. | Simple breast-conserving cancer surgery |
(histologically complete tumour excision, performed as a "wide excision" up to quadrantectomy with defect repair involving only direct apposition without mobilisation of glandular tissue or skin flaps) | |
2. | Complex breast-conserving cancer surgery |
(additional intramammary reconstruction of the mammary gland by mobilisation of subcutaneous or epifascial glandular lobes and, if necessary, mobilisation of the skin envelope for defect repair of ≤ 25% of the area of the breast) | |
3. | Oncoplastic breast-conserving surgery |
(additional intramammary reconstruction of the mammary gland by mobilisation of subcutaneous or epifascial glandular lobes and, if necessary, mobilisation of the skin envelope for defect repair of > 25% of the area of the breast) | |
4. | Complex oncoplastic breast-conserving surgery |
a . | Tumour-adapted mastopexy (breast lift) without additional removal of healthy breast tissue |
(selection of skin incision pattern depending on amount of excess skin and desired scar pattern, i.e. purely circumareolar, vertical, segmental or "inverted T") | |
1. | Central pedicles |
2. | Inferior-central pedicles |
3. | Cranial pedicles |
4. | Modified B mammoplasty |
5. | Free nipple transfer |
b . | Tumour resection with defect repair using local flaps without or with skin replacement |

1. | Central pedicles |
2. | Inferior-central pedicles |
