Facial Plastic Surgery: Q&A
Ask a QuestionMedpor or Silicone Jaw Implants?
I have had a number of consultations with my maxillofacial surgeon about jaw implants and he says that Medpor is the better of the two and that silicone has a much higher rejection rate, and would probably have to come out at some point. Is this true? Because I hear many scare stories of how difficult Medpor is too remove? And which in your opinion gives the better end result?

Rejection rate for Medpor vs. silicone implants
We perform a great number of silicone chin implants and the rejection rate is almost nil.
Reoperations, if they are ever necessary, are very easy with silicone implants. They are a nightmare with Medpor because of the adherence of Medpor to the underlying bone. So if you are not happy with the shape of your chin, hope you had a silicone implant.

Medpor or silicone implant for the chin and jaw
In my experience, chin implants work great with either silicone or medpor implants. Once you involve the oral cavity and any approaches with this it gets to be more prone to issues like infection when you use medpor. There are ways to avoid this but you have to be meticulous and there is no room for less than a perfect approach and procedure with jaw and chin implants using med por in my opinion. I do have know those elements that you need to get a great result with medpor...

Silicone jaw implant preferred over medpor
Medpor is a very porous substance that when used is extremely difficult to remove. Silicone jaw implants are quite easily removable if ever necessary. Medpor has a higher rejection rate than silicone. Silicone jaw implants will give a better end result for long-term stability and less likely have infection.

Silicone versus Medpor facial implants.
I have used both and have essentially returned to silicone implants for two reasons:
1) the Medpor is desireable because the density and structure is comparable to bone. It promotes tissue ingrowth and it does not tend to erode the underlying bone which the older silicone implants had a tendency to do. The problems I encountered were the larger incisions, difficulties in placement, problems with contouring to the underlying bone, and complicated removal.
2) Silicone implants do not...

Pros and cons of Medpor and silicone jaw implants
Surrounding tissue does not grow into/through silicone, therefore it is easier to remove at a future date should the need arise. It can also shift in position at any future date since there is little or no ingrown tissue to keep it in place.
Porex Medpor does develop tissue ingrowth or incorporation. The ingrowth may not be 100% but ingrowth prevents future shifting in position. It also decreases the risk of infection. Ingrowth should be complete within a few weeks, fixing the implant in...
