Dear Lesh1953, Thank you for your clinical post. It is quite common to see patients with chest wall anatomical variation such as a protruding sternum or excavated sternum or flat or rounded chest walls and asymmetries. Experienced surgeons will work with you and devise a plan that accommodates your chest wall shape and size. In my practice I adopted a high-tech 3D imaging system called the Vectra 3D approximately 6 years ago. This high-tech 3D breast imaging system allows you to confirm various sizes of implants and shapes with a great degree of accuracy the post-operative appearance that will likely be achieved. In meeting with my patients I devise a plan of incision, pocket selection and implant type, round or teardrop, saline or cohesive gel depending on the goals and concerns and various anatomical and tissue characteristics including the sternum. I then provide several sizes that I think will work well and patients then do a 3D imaging, look at those sizes as well as others until they arrive at the best possible implant selection for them. This try before you buy eliminates a lot of the stress and certainty around breast augmentation surgery and it certainly results in a very high instance of patient satisfaction. At this point it’s important you seek the consultation of experienced plastic surgeons and Toronto has many of them to decide on the right implant approach and model and size for you. I hope this information has been of some assistance and best of luck. For more information, please review the link below. R. Stephen Mulholland, M.D. Certified Plastic Surgeon Yorkville, Toronto
