Thank you for posting your question here!My answer will be based on the limited information and pictures provided, for a more detailed and personalized plan please consult with your plastic surgeon in person . It is hard to tell if there is an issue with your implant just based on an AP xray , what you are seeing could be the gastric the bubble ( air in your stomach), that shows on xrays, xrays can look different based on the energy and exposure being used and they only gives you a 2D image. The gold standard for monitoring implants continues to be an MRI, though increasingly people are using ultrasounds.So if you are having symptoms or you are worried about your implants , I would encourage you to ask for an MRI.I hope this helps, best of luck!
