What happens after explant/capsulectomy if no drain tubes are used?

Drains are sometimes used after implant removal to help collect healing fluids and prevent seroma formation. If a seroma develops your surgeon can aspirate it in the the office. Sometimes multiple aspirations are needed. If the seroma persists another drain may be placed or it may even be surgically addressed. I encourage you to discuss your concerns with your surgeon.

Not all surgeons drain breast pockets after explantation. You might be at slight increased risk of fluid accumulation.

If it was a simple implant removal without manipulation of the capsules a drain usually is not needed in my experience. There may be a bit of fluid after but this eventually gets reabsorbed. If you are having a capsulectomy I would recommend a drain since this is much more involved. If you feel more comfortable with a drain, ask your surgeon. They most probably would comply.
