Implant placement - should I leave it or get it fixed?

If the location of your implants are not really a problem and you look good in and out of your clothes, you might leave things alone. Sometimes implants do slip out from behind the muscle.

Are you having a problem with your implants? Is the outcome not desirable?
Usually there needs to be a good indication before having surgery.
It is highly unlikely a surgeon would place one implant under the pectoralis muscle, and not do the same on the other side, unless there are unusual circumstances.
Why don’t you ask for a copy of the operative report which describes exactly how the procedure was performed.
It sounds like you need to have a little more faith in your provider.
He can also schedule an in person second opinion consultation.
For second opinion consultations come prepared bringing with you a complete set up before and after pictures and a copy of your previous operative report.
Best,
