Would a 275cc or 300cc silicone implant under muscle be best, for achieving my desired result? (photos)

Thank you for the question and photos. Based on your photos only, I believe either implant size will give you a good result. If both implants fit your measurement, then I would choose the larger one. The volume difference is less than one ounce. Wouldn't lose sleep over it. Good luck with your surgery.

Thank you for your question. It's difficult to give sizing advice online, without an in person examination, measurements, and most importantly getting a sense of your overall size goals.It's important to remember that 15cc = 1 tablespoon, so the actual volume difference between the 275cc and a 300cc is pretty small. Based on your photos you have a good starting place for augmentation surgery, and guessing that you will be happy with either size. Your correct that the muscle pushes the implant down slightly and makes it appear slightly smaller.Congratulations on your upcoming surgery.
