Textured silicone implant under muscle is poking out bottom of breast less than 2 months post surgery. What can be done? (Photo)

There are several possibilities to consider, such as capsular contracture, but likely the capsule was thin which would explain why the implants moved to the side when you lay down. Tightening the capsules and replacing the implants was certainly a good plan, but does not add coverage and support to the lower breast. If the capsule is thin then reinforcement would be needed, possibly with GalaFLEX mesh or Strattice. If not, the reshaping the pocket would work.

That may be an implant crease and can be followed to see if conservative measures improve it.Close follow up with your plastic surgeon is recommended. 

I think your implants have bottomed out slightly.  You will require some revision probably to both sides.  I don't think it is a bad idea to with a few months but i doubt this will happen to the other side.  I would think about a releasing the superior capsule, tightening the lower capsule, and possible fold excisions.Best Wishes,Nana Mizuguchi, MD
