Has the Keller Funnel Caused a Decrease in Chance for Capsular Contraction?

In your experiences have you seen a decrease in capsular contraction incidents after using the keller funnel on areola incisions. Thanks for your time.

Does The Keller Funnel Reduce The Risk Of Capsular Contraction?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

    Dear Rosy81,     The Keller Funnel is a wonderful device that has many benefits already listed by my colleagues. They include: smaller incision size, less trauma to the implant, less trauma to the incision itself, ease of use for the surgeon and reduced risk of implant contamination. I use this device on ALL of my silicone implants and I am able to place the implant into the pocket with a no touch technique. As you have read, most of us believe that this will lead to less capsular contractures. Studies are under way to confirm this belief. I would whole-heartedly recommend using this device.

The Keller Funnel insertion sleeve reduces capsular contracture

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Capsular contracture has been the number one complication of breast augmentation. Nationally this has occurred in up to 30% of breast augmentation surgeries. This is a complicated process with many factors to consider. The best current theory is that trace bacterial contamination of the implant stimulates white blood cells to release factors that over time can cause the capsule to contract. This can cause the implant to feel hard and look round and elevated. Other factors such as bleeding around the implant can also cause capsular contracture, but this is a minority of the cases. The current standard of practice is to make every attempt to reduce the chance of bacterial contamination of the implant during surgery. Even after a surgical prep, there are still bacteria on the skin and there are normally bacteria in the milk ducts. To minimize the risks of contamination, intravenous antibiotics are given at surgery. The implant and surgical field are irrigated with a combination of several antibiotics. The Keller funnel is a device much like a pastry bag that allows the implant to be inserted without contacting the skin or breast tissue. Since the milk ducts are normally colonized with bacteria, I recommend avoiding the peri areolar incision and use an inframammary crease incision to reduce the chance of contamination. Using these techniques, the incidence of capsular contracture has been reduced to less than 5%. If you are adamant about a periareolar incision, I think you may have a higher risk of capsular contracture but it would still make sense to use an insertion sleeve such as the Keller funnel. Him

The Keller Funnel should be used in all breast enhancement procedures

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The Keller Funnel is a wonderful device.   The idea is simple, yet genius.  I wish I had thought of it.  I use it on every single silicone breast implant that I place because it certainly does several things:

1) minimize incision size

2) minimize pressure on the implant shell and thus likely extend life of the implant

3) reduce potential bacterial contamination and infection and/or capsular contracture.

To me, it is a no brainer.  Why not use it?   Well, it costs about $125 per funnel list price.  Is it expensive?  Absolutely.  Is it worth it?  It is worth every penny....

Capsular contracture is miserable to deal with.  The funnel is a simple and easy way to minimize risk and while it is impossible to do a study where one side has the funnel and one doesn't to see if it really reduces capsular contracture, the downside is so minimal that I believe it should be used.  

Ask your surgeon about the device, and if he does not use it, ask why not?

Keller funnel and capsular contracture

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

great question!!!! current theories suggest that capsular contracture may be due to contamination with biofilm. an interesting study with the keller funel on cadavers suggest that the funnel is very effective in reducing contamination of the implant. we are currently involved in a study to look at capsular contracture rates with the funnel. so far we think it reduces the risk.

please note that i was asked by one of the implant companies to evaluate the funnel before it became available. i liked it so much i invested in the company and am currently on their advisory board!!! i have used it in every silicone implant case since they became available.

I always use the Keller Funnel!

The Keller Funnel® 2 increases patient safety and simplifies implant placement.   The improvement it provides is so significant that I use it for every breast augmentation I preform.  Before the Funnel came along the most common method of getting the implant into the pocket was the digit method.  This meant that the surgeon’s fingers had to push and position the implants.  The digit method increases the rate of infection and other complications. The obvious solution is to never touch the implant to begin with.

The Keller funnel is not necessary but it does decrease the risk for contamination and damage to the implant and surrounding skin. It's the no-touch technique. I use it every time I'm inserting an implant.

Does the Keller Funnel decrease capsular contracture rates?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
The Keller Funnel is a simple but effective device that aides in the insertion of gel breast implants into the breast pocket.  It allows for very minimal or no touching of the implant to the skin. This dramatically decreases the potential for implant contamination with bacteria.  That in turn translates into the potential for a lower risk of capsular contracture.  It also allows for a shorter skin incision and less trauma to the implant during insertion.  Combining the use of the Keller Funnel with excellent surgical technique and irrigation of the pocket and the implant with antibiotics should reduce the risk of capsular contracture to a very low percentage.

Keller funnel will reduce surface contamination of implants

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
There are many suspected causes of a capsular contracture but the most likely causes are implant contamination, bleeding and infection. Surgical technique is critical as prevention is the cure for capsular contracture. The risk of a capsular contracture when implants are placed above the muscle is in the 20 to 30% range. When the implant is placed either subfascial or sub muscular the risk is in the 4 to 7% range. The no touch technique was first described in 1991. This means avoiding any surface contamination of the implant during insertion. The no touch technique combined with irrigation with antibiotic and betadine solution as well as use of a funnel has greatly decreased the risk.

Keller Funnel

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
The Keller Funnel is widely thought to decrease the size of the incision to place silicone implants while using the no touch technique. Capsular contracture can introduce bacteria from the skin and this technique can limit or eliminate the implant from touching the skin. To be sure, capsular contracture and the cause thereof is poorly understood. It seems the best benefit of the funnel is to create a smaller incision and apply a large silicone implant through the axilla (underarm) or nipple areola incision. Hope this helps.

the funnel has no effect on capsular contracture. It however does reduce the size of the incisions for access and facilitates surgery
