When doctors try a different breast implant size during surgery, will that increase capsular contracture?

Capsular Contracture is most likely caused by biofilm which is the result of bacteria entering the pocket and colonizing the surface of the breast implant. During surgery, most board certified plastic surgeon who specify in aesthetic breast surgery will use what is called a no touch technique which minimizes bacterial inflow to the pocket. Use of antibacterial and irrigations, use of a no touch delivery device, use of antibiotics, change of gloves, and multiple other technical things will minimize the risks of capsular contracture. Even when sterilized sizers are used, a Keller Funnel is always used again minimizing the risks of bacteria entering the pocket. So in answer to your question, when multiple sizers for implants are placed in to the pocket, as long as an antibacterial, no touch technique is utilized, the risks of capsular contracture are not increased.

Dear rainrain90,
capsular contracture happens. In fact, every implant has a capsule form around it, its just a certain percentage develop thick capsules. There is a lot we don't know about it actually. Some think that bacteria that gets on the implant during insertion can increase the risk. Thats why we use a Keller Funnel in our practice to reduce that possibility. Our capsular contracture rate is less than 2% because we use a keller funnel as well as meticulous operating room techniques.

Any implants that are placed inside a patient’s body should be sterile and typically, only one implant is placed rather than “trying out” different sizes. The size is determined before surgery.
