Silicone Breast Implants and the Keller Funnel

When you’re finding out all you can ahead of a breast augmentation surgery you may come across a few terms you don’t know the meaning of!

Like… what is a Keller Funnel?!


Straight up, all surgery carries the risk of complications.

Things like bleeding or infection are a risk of all surgical procedures. With a breast augmentation the most common complication is something called capsular contracture.

Capsular contracture is when thicker-than-normal scar tissue forms around the breast implant, which tightens and causes changes in the look and feel (pain and discomfort) of the breasts.

It is a complication that can be fixed (with further surgery) but… prevention is always better than cure!

Your Board Certified plastic surgeon will use their knowledge and surgical skills to ensure your breast augmentation goes smoothly and that any risks or complications are minimized. This includes minimizing your risk of capsular contracture.

For example, things like ensuring your surgery is carried out in sterile conditions - meaning it minimizes the presence of bacteria, which is theorized as being linked to capsular contracture.

There are also ‘tools’ that surgeons can use to ensure the risks of surgery are minimized or just to make the surgical process smoother. The Keller Funnel is one such tool which is used by some surgeons to minimize the risk of capsular contracture AND make surgery smoother.

The Keller Funnel

The Keller Funnel is a surgical tool that was created by a surgeon around 10 years ago after he noticed how difficult it was to place a silicone breast implant through a small incision.

When placing a silicone breast implant a surgeon would normally need to use pressure from their hand to push a breast implant in through the incision bit-by-bit.

The Keller Funnel was born to help make the insertion of silicone breast implants via small incision site much MUCH easier!

And a Keller Funnel looks like… an icing bag!

The Keller Funnel

The silicone breast implant is placed straight from its sterile packaging into the top (large) end of the funnel (without the surgeon touching it). The Keller Funnel is lined with a special solution to help the implant slide through the funnel and out the bottom (small) end. Placed against the incision site, the breast implant is placed into the breast pocket via the funnel. All of this happens without the surgeon ever touching the breast implant!

When using a Keller Funnel a surgeon can perform a ‘no touch’ technique, meaning the risks of introducing bacteria are minimized thus minimizing the risk of capsular contracture.

Capsular contracture (CC) is something you should be aware of as you start your breast augmentation journey. It’s also good to know that there are things your surgeon will do to minimize any risks of complications from surgery.
