I felt fully informed and comfortable before surgery. The perfect breast shape for natural breasts should have a little more breast volume below the nipple than above with nipples tilted slightly upward. One limitation is in implant sizing. Yates injects the area with a lot of local anesthetics. Are you a good candidate? These implants are more cohesive than other round silicone implants, and as such, are able to be manufactured in a teardrop shape. It is also harder to correct surgically, as the implant material may need to be removed as well.
