Key messages for GPs

• Oncoplastic volume replacement (e.g. local intercostal artery perforator / LICAP flap) can fill a large wide-local-excision cavity so women with a moderately sized breast and a ~3–4 cm tumour may keep a breast with less contour deformity — they still need radiation when indicated.
• Smoking is a major reconstruction risk; ideally ~3 months off (often longer in practice). Cotinine testing exists but is rarely used; threat of testing may be enough.
• Fat grafting is used to thicken skin, reduce rippling, and improve irradiated fields — ideally after adjuvant treatment and once skin/implants have settled (~6 months preferred by the speaker); inject in linear subcutaneous passes, not blobs.
• Radiation permanently affects the hemithorax; exposed implants after radiation are hard to salvage; autologous tissue failures are often more recoverable than a lost implant.
• Long shared-decision consults (second visit, family present) matter — many patients do not know conservation options exist.

Oncoplastic conservation and LICAP flaps

Speaker 1 framed modern breast conservation: for a three-centimetre tumour in a moderately sized breast, mastectomy used to be routine. If the tumour is in the right place, the team can take a flap of the patient’s own skin/tissue, de-epithelialise it, swing it on its pedicle into the cavity after tumour excision, and fill the space so symmetry and contour are better preserved.

The worked example was what Otter transcribed as a “white cat flap”, clarified in the same breath as a local intercostal artery perforator (LICAP) flap. A patient with ~4 cm tumour had the flap inset, went on to radiation, and finished with less deformity than a large cavity alone would have left. Scar from the flap harvest was part of the trade-off.

Implants, perfusion checks, and MDT

Beyond conservation, Speaker 1 listed reasons reconstructions feel better for patients when complications are avoided: keeping a breast or getting a reconstructed breast supports identity through the cancer journey. Technical advances mentioned:

• Cohesive-gel implants framed as less prone to rupture and with fewer capsule / immune-type problems than older devices.
• Intraoperative ability to check flap blood supply — “almost like fluoroscopy” — to see perfusion at the time of surgery.
• Strong MDT collaboration with other breast surgeons, oncology, and radiology to decide who qualifies for which pathway.

Prophylactic and cancer vignettes

Prophylactic bilateral reconstruction

A woman with a high-risk family history, lifetime risk framed as about 50–60%, who had not completed BRCA testing as told in the talk (“did not have the bracketing” in Otter), was having frequent MRIs and, after psychology input, chose bilateral reconstruction and wanted to go smaller with a natural look. Challenge: naturally lateral nipples can look even more lateral after implants and stitching. Post-op plan included fat grafting to thicken skin and reduce rippling.

Young cancer — thin flaps

A young patient with right breast cancer, lateral nipples and some ptosis, and a large tumour very close to skin edges needed thin flaps on the cancer side. The reconstructed side looked a little thinner with some colour change; she was mostly happy and had fat grafting afterwards.

Smoking, cotinine, and fat-graft timing

Smoking can “bite you” if patients lie — ideally three months off for reconstruction (said to match public-sector expectation). Minimum three months was restated in Q&A; duration also depends on adjuvant treatment — wait until systemic therapy is done and health recovers.

For fat grafting after implants, Speaker 1 prefers about six months: skin healed, implants settled, and early rippling often improves as fat redistributes over the implant before more fat is placed.

How fat grafting is done

Q&A detail from Speaker 1:

• Harvest with a MicroAire-style liposuction device; tumescent fluid with local anaesthetic and adrenaline into abdomen or inner thighs (wherever spare fat is).
• Collect what is needed — sometimes up to ~500 mL — without creating donor-site defects.
• Speaker 1 does not wash the fat (notes some surgeons do); load into small syringes.
• Inject with a thin flat-ended tip (not a standard gauge needle) into the subcutaneous fat plane.
• Use slow linear passes, not blobs — blobs risk fat necrosis lumps that feel like new “cancers.”

Animation deformity

Asked about the term animation deformity: when an implant sits under the pectoralis and the capsule adheres to the back of the muscle, flexing the pecs squeezes the implant so it visibly moves up and down. Can happen in cosmetic augmentation and in reconstruction.

Shared decisions and breast implant illness

Patients increasingly arrive having used ChatGPT, Google, and friends, already wanting reconstruction — which can limit influence toward a conservation pathway, though the surgeon still gives an opinion on the tumour and the least invasive sound option. Roughly 50% walk in with a preference (half of those may change); ~50% want to be guided. Many do not know options beyond “cut the breast off.” Long consults, a second visit, and bringing a family member help information land. Breast implant illness questions sit in this shared-decision era.

Complication case: radiation, expanders, infection

Speaker 1 presented (at David’s request) a delayed-reconstruction failure:

• Met at age ~56 (now 58 in the talk); right breast cancer 2017 → wide local excision + radiation → early recurrence ~6 months later → bilateral mastectomy without reconstruction (patient unsure why; speaker assumed radiation).
• Long-term Herceptin via portacath.
• After ~6 months of planning: sub-pectoral expanders chosen because of infection risk after radiation; radiated side tethered with some ooze/oedema but thick, mobile skin — felt relatively safe.
• Week 1: dramatic rash under Cranio dressing — allergic reaction; settled immediately when dressing removed.
• Expanded over ~6 months to ~400 mL each side; infection risk highest when needling the expander.
• Implant exchange + fat grafting to toughen skin — initially healed well.
• ~2 weeks later: febrile leak on the radiated right side with implant on view → return to theatre.
• Salvage with a Veraflow-type instil-and-suction saline wash machine (Sydney experience); grew Staph aureus; implant replaced; long antibiotics with Dr Jones.
• Weeks later (around early January after a pre-Christmas period): breakdown again; room sutures and simple vacuum dressings failed to hold.

Panel: radiation, Veraflow, Craig’s salvage view

Radiation as lasting enemy

A colleague (referred to as Dr Sheena by another speaker) stressed that radiation is “the gift that keeps on giving” — the hemithorax is affected for life; revisions and fat grafting are common. Free flaps can still look compromised even when the flap itself was never irradiated — likely recipient-vessel territory. Advantage of autologous: if the flap suffers, patients often still smile — you fat-graft toward symmetry rather than losing the whole reconstruction the way an exposed implant can vanish overnight.

Veraflow / irrigant salvage

Speaker 1 recalled limited Sydney use (~2–3/year) with some success. Another surgeon’s New Zealand risk-reconstruction experience with Veraflow was not successful for colonised implants; antiseptic irrigants (Otter: “Hong sin” / similar) were mentioned as sometimes endorsed, still with poor salvage once the implant is frankly infected and exposed.

Craig’s senior view

• Fat graft irradiated fields (often repeatedly) — softens tissue; framed as a stem-cell-type effect; take improves on second sessions (~50% then ~90% in aesthetic analogy).
• Autologous tissue with its own blood supply similarly improves the surrounding bed.
• For implants that look infected: generally remove, clean, wait ~three months, then replace ± fat graft — because “salvaged” implants often return with worse capsule/contracture (orthopaedic prosthesis analogy). Stated few losses over 26 years and >10,000 implants; rare true durable salvage.

MDT and psychosocial support

Asked about psychology services: Speaker 1 described a monthly MDT (Otter garbled the group name), routine phone calls to referred oncology / radiation / radiology colleagues for complex cases, and heavy use of breast care nurses at Pindara (one also works from the rooms). Nurses link younger women (<35) to foundations — Otter heard “yellow freesia” — and to psychologists; physio involved when needed. No on-site psychologist in that private setup — a close-knit phone network instead.
