Techniques for Oncoplastic Surgery

• Local Tissue Rearrangement • B to C cup breast •Small tumor •Grade 1 ptosis •No skin resection

• Oncoplastic Reduction Mammoplasty •C to D cup breast •Grade 2 to 3 ptosis •Some skin resection

Local Tissue Rearrangement

Oncoplastic Reduction Mammoplasty

-Use of neoadjuvant

chemotherapy

-Breast conservation

therapy (BCT)

-Oncoplastic mammoplasty

-Extends BCT option

-Improved cosmetic results

-Minimizes adverse

effects of XRT

Indications

- Minimal Skin Resection or Tumor within Wise

Pattern

- C-Cup Breast Size with ptosis or Small Tumor

- D-Cup Breast size

- Neoadjuvant chemotherapy

- Post-operative radiation therapy

•Oncoplastic mammoplasty with equivalent oncologic safety

and fewer complications in setting of neoadjuvant chemo and

•Early evaluation by plastic surgeon/multi-disciplinary

approach

•Role in pre-operative patient

counseling/decision-making

Conclusions

Low rates of local-regional recurrence

No recurrences in the NAC

Low rates of ischemic complications

Targeted technical improvements

-Incisions avoiding NAC

-Minimal pressure on NSM skin flaps

--2-stage tissue expander reconstruction

--Delayed autologous reconstruction
