Breast Implant Surface Type, Capsular Contracture & Re-Operation for Augmentation

Aug 2, 2011 by

Blah, blah, blah. I keep writing about and linking to information about capsular contracture.

But, this is important.  Capsular contracture is the leading reason for re-operation following breast augmentation. And there are studies comparing the rate of capsular contracture for each breast implant surface type. The common breast implant surface types are smooth and textured, with Polyurethane foam used in many countries, but not the USA.

Note- the discussion is not about the size or shape of the implant or even the manufacturer, but the type of implant surface. Every implant has a “shell” that is filled with silicone (or, formerly, saline for the USA breast implant market); the shell surface is what is focal point of the discussion.

There is a kind of breast implant surface with documented studies showing it reduces capsular contracture- Polyurethane foam. There are studies that show that Polyurethane foam breast implants have a lower rate of capsular contracture in primary augmentation and in re-operations following breast augmentations.

Here is a link with a summary article about how polyurethane foam covered silicone gel breast implants have a lower rate of capsular contracture than smooth or textured breast implants:


A highlight from that article (note, this company calls Polyurethane MPS for Micro-Polyurethane Foam Surfaced) :

Capsular contracture
The capsular contracture rate, respectively the risk
for capsular contracture, was determined in two
Capsular contracture (Baker III or IV) as a function
per 1,000 patient months follow-up over all
indications was:
 6.29 for smooth implants;
 3.03 for textured implants;
 2.19 for MPS implants.
The Kaplan-Meier survival analysis confirms
the significant reduction of the risk for capsular
contracture with MPS implants for up to ten years
after implantation.
Eight years after implantation 80% of the patients
with MPS implants remain contracture free,
whereas only 65% of the patients with textured
implants and only 50% of patients with smooth
implants are still without capsular contracture.
After eight years the superiority of MPS implants
to textured implants is therefore 15%, compared to
smooth implants it is even 30%.

And another note- I don’t work for the implant company from the link and had nothing to do with that article; I don’t work for any implant company.
