Can a concaved chest (pectus excavatum) be fixed with chest implants/plastic surgery instead of a hospital operation?

It's still surgery: The answer is yes, it can be fixed with implants (not the best solution) and/or plastic surgery. Either procedure is surgery. In the past a procedure called the nuss procedure was used to correct the shape of the rib cage using an implanted metal plate and i assume you are referring to this procedure. Recently fat injections have been used to correct minor deformities.

Yes. fat grafting .: Fat grafting tecniques allow for fat and bulk to soften the appearance of the depression associated with pectus excavatum. This technique is much less involved than some of the more traditional manners of correcting this problem. It can be performed as an outpatient with minimal recovery, scarring, or down time.

Yes : Assuming the pectus excavatum does not require reconstruction for physiological purposes ( limitation of cardiopulmonary function for example), the “defect” can be camouflaged with custom-made silicone implants.
