Prominent Chest or Constricted Breast?

From your photograph, it appears that your chest prominence is less of a problem than is your breast deformity. Your right breast is somewhat underdeveloped and is a mild form of what is called "constricted breast deformity" or "tuberous breast deformity." In your case, correction of the right lower breast fold is going to be the most difficult portion. I do not think that it matters whether you go with an anatomical or round implant, though I feel that round implants generally look more natural once healed.
