Silicone or saline? - Will 425 cc in silicone look as big as 425 of saline?

I agree that, in general, saline implants seem larger (more projection) than silicone implants (which tend to conform to the chest wall). Determining exact implant size is very difficult. Consult your board certified plastic surgeon to discuss the best and safest possible option for you. Every surgeon has a certain technique to determine the best implants to use. It is very important that I communicate with my patients prior to surgery to discuss the look they would like to achieve. Intra-operatively, I use sizers to determine the size and the profile of the implants to be used. This is best determined based on the patient’s body type and overall goals. The main difference between saline and silicone is the feel of the implant. Silicone gel is the more natural feeling of the two. Saline is not recommended for patients without enough coverage or breast tissue to begin with.

Hi, the difference in dimensions between saline and silicone is a factor of the profile, diameter and volume of the implant.  Your surgeon will guide you between the different profiles and diameter, at the same volume, based on your expressed preferences on breast shape, cleavage, etc., and your physical examination.  The ability to distinguish the saline implant from surrounding breast tissue is easier than a silicone implant, especially if the implants are placed above the muscle.  So, it is easier to make a breast appear "larger" by placing a full/high profile, fully filled saline implant above the muscle.
