I had 295cc subgland. polyurethane implants for 5 years with late onset contracture (potentially due to an old haematoma found in surgery). After explant, my breasts are similar to pre-surgery, a small 34a. I would be happy with a modest increase to a full b cup (with 295cc I was 32dd). What would give best / safest long-term outcome: new small implants under the muscle or fat transfer?
