Can the chest implants for pectus excavatum shift?

Tags:man age 25-34 chest natural looking natural pecs

I suffer from severe pectus excavatum (a deformity where the sternum grows with a caved-in appearance). I developed this condition when I was a kid, and I think that I've finally had enough, I want to get my chest fixed. Fortunately, my pectus excavatum doesn't seem to cause any medical problems, and I want to correct it for esthetic reasons, which are of major importance to me right now. If someone has had this procedure or has information about it, can you please let me know if the results look natural and, more importantly, if there's a risk that the chest implants could move?
