Best Ways Pre and Post Surgery to Avoid Capsular Contracture?

I would have to agree with most of the comments made previously.
No matter what is done during surgery, this is a biological process and no once can ever predict the outcome or necessarily prevent capsular contracture. It is a highly controversial topic for which we still have many unanswered questions.
As stated, the two most popular theories relate to either:

blood around the implant
low grade bacterial contamination around the implant, called a biofilm

In the first case doing all you can do to minimize bleeding requires:

meticulous control of bleeding during surgery some surgeons feel it is best performed with a bipolar cautery but this is not proven
limited/controlled postoperative activity
avoidance of aspirin, etc.
ice compresses
some feel compression is useful

In regards to the second, options to potentially minimize biofilm include:

Perioperative antibiotics
Triple antibiotic irrigation during surgery
Multiple glove changes
Use of a nipple shield, tegaderm, and insert sleeve during surgery
The use of silicone vs saline implants is controversial in regards to capsular contracture.
Placement under the muscle seems to be correlated with lower capsular contracture
Placement throught the breast crease is believed to be the source with the least potential of contamination

Postoperatively: options include::

Breast implant displacement excercises
The use of accolate is controversial
The use of Vitamin E is generally felt to be of little benefit

In cases of recurrent capsular contracture at the time of implant exchange it is probably best to perform a complete capsulectomy (not partial or capsulotomy) and use a completely new implant.

Capsular contracture may recur regardless of surgeries being performed at this time and may require additional surgeries. There is as much as a 40% chance that additional surgery will be needed following this operation. 
Nicotine users, such as smokers, have up to a 30 times increased #risk of capsular contracture. The #reason capsular contraction happen is unclear. It's possibly caused by microscopic bacteria on the implant, a   collection of blood after surgery or perhaps it is a tendency for some women to form scar tissue. What we do know is that is cases reported have decreased from 25% to  5-10% or less.
One way to attempt the prevention of it is to follow your surgeon's post op instructions as recommended and ask questions of your surgeon when healing concerns arise.

There are things that the surgeon can do to reduce the risk of capsular contracture, but in medicine we cannot 100% guarantee that you will not experience capsular contracture. In your case, with a history of capsular contracture, your risk may be higher just due to your body's wound healing biology. To help prevent recurrent capsular contracture, one can use pre and post op singulair for 3 months or use an ADM in the pocket (i.e. alloderm, strattice). While this is not 100% preventive, it may help reduce the chances as much as possible.You should be sure your surgeon is well-experienced in not only treating patients with capsular contracture, but also using the most advanced techniques available that we know mitigate the risks of capsular contracture. First, the surgeon should make sure everything is very sterile and antibiotics are used to reduce the chances of an infection. Second, you want to go to a surgeon who uses an advanced technique that minimizes the amount of bleeding during surgery. Best of luck!

Capsular contracture is one of the most difficult
problems seen following breast augmentation surgery. For this reason every
effort should be made to avoid this complication before it occurs. Even when
these efforts are made capsular contracture may still occur because of wound
healing biology.Several steps can be taken at the time of surgery to
minimize the potential for this complication. These include submuscular implant
placement, avoidance of large implants, meticulous hemostasis, and avoidance of
infection and biofilm formation.Following surgery, most surgeons recommend implant
displacement exercises. When early signs of capsular contracture are noted,
some surgeons start their patients on a course of vitamin E or Singulair. Many
surgeons feel that these maneuvers are helpful, but no scientific evidence is
available to support their use.Despite these efforts, capsular contracture may still
occur. If capsular contractures occur and don’t respond to conservative
management surgical intervention may be necessary.If you have a history of capsular contracture, it’s
important to discuss the management of this problem with your plastic surgeon
prior to surgery. Your surgeon should be able to formulate a treatment plant
that minimizes the potential for this complication.

Hello! Thank you for your question! Recurrent capsular contracture is a very difficult problem. Assuming you tried conservative measures in the past - implant massage and may add the medication Singulair and Vitamin E. If these fail, surgical correction may be necessary. It is a matter of surgeon preference as well as what is seen during your procedure that will determine whether or not a complete capsulectomy is performed. If significant capsule formation is seen intraoperatively, a full capule removal may be warranted with a drain in order to completely remove all of the tissue and allow better adherence of your breast back to its normal anatomic position down on your chest wall. Irrigating with certain medications may also be if benefit. Some other things that may have been tried include changing the position of your implant, addition of a dermal matrix, or consideration for the the shaped, textured, anatomical gel implants. Without knowing your issues and without an examination, it is difficult to tell you what may be the best thing for you. I tend to favor performing capsulectomies in order to create a fresh pocket, reshape the pocket, allow better shape and adherence of the overlying breast. I would discuss your issues with your plastic surgeon who will assist you in determining the right modality for you. At a 3rd recurrence, it may continue to occur despite all of these modalities and consideration for explantation or living with the contracture are options. Hope that this helps! Best wishes!

Capsular Contracture is always a risk with any breast augmentation, and in your case, given your history, it is likely a higher risk than in the average patient. As the other doctors have written, 2 things we know increase the risk of capsular contracture are blood around the implant or a low grade infection. With this in mind, I think it's important to pick a surgeon who prides him or herself on meticulous techinque, not just fast technique. Given what we know about what increases the risks of contracture, namely blood around the implant or infection around the implant, I think it's crucial to pick a surgeon that will take his time and do everything possible to avoid these problems.
That being said, the risk always exisits, and the surgeon may do everything right and you could still end up with a contracture. I also agree with the idea of not choosing implants that are too big, and perhaps placing the implants under the muscle, in particular if they are not there already. Some surgeons really believe in this, others think there is no great data to support this, but in your case, I would try everything possible to give you the best result.
Good luck,
Dr. Salemy
