Q: Dr. Eppley, I have a question regarding capsule formation that I was hoping you could clarify. I have heard what I believe is misinformation that the material of Medpor facial implants produces a different aesthetic outcome than silicone facial implants in terms of chin/jaw implants . The reasoning this individual used was that silicone implants form a capsule and therefore the appearance of such an implant will always appear “off”, and that Medpor implants will not result in such a capsule.
Correct me if I’m wrong, but I believe that Medpor also forms a scar capsule (albeit a smaller one) and that while silicone forms a capsule, it is not one that has any significant or noticeable aesthetic impact. Capsular contracture can form aesthetic complications, but that is a actually rare complication not common to chin or jaw implants.
Is my understanding correct? If one were to make a custom silicone implant the exact same size and shape as a Medpor implant, wouldn’t the aesthetic outcome be identical?
I would appreciate any clarification you could provide on this topic.
A: All implants placed in the body produce a surrounding scar, whether it is a facial implant or a breast implant, regardless of the material. This is a natural protective reaction of the body. (self vs non-self) Thus both silicone and Medpor facial implants produce a surrounding scar (capsule) with the only difference being is that the capsule produced around a Medpor implant will be more adherent or stuck due to the irregular semiporous surface of the implant. The scar capsule will also be slightly thicker as a result.The internal surface of a silicone implant capsule will be very smooth (and thinner) since the implant surface is smooth. But beyond that, the biology and make-up of both implant material’s capsules are similar.
From the outside and its aesthetic results, identically shaped and sizes of Medpor and Silicone facial implants will look the same.
