Can a Seroma/hematoma Be Absorbed by the Body on Its Own...how Long Will It Take?

It’s not unusual for small seromas to resorb on their
own. Unfortunately your pictures indicate the presence of a large fluid
collection. Whether this collection is the result of a seroma or hematoma, it
needs to be drained.

For this reason, the vast majority of plastic surgeons
would drain this fluid collection and explore the breast pocket to determine
its cause. Failure to adequately treat either a seroma or hematoma could have
long term adverse consequences. Under these circumstances, capsular
contracture, infection, and even loss of the implant could result.

It’s important that you discuss drainage of this fluid
collection with your plastic surgeon. Failure to adequately address this
problem could have significant long term consequences.

Seroma is a condition involving the collection of clear tissue fluid around the implant that may need to be drained, although it could be absorbed by your body. However, seeing your photo, I would recommend you have it drained because it is quite prominent.

If there was acute trauma and an abrupt change in size, it usually needs to be drained.  If it is not drained and it needs to be, there will be an increased risk of infection and capsular contracture, as well as implant exposure.
