Do you lose implant volume when you place implants in a subfascial position just as you would in a subpectoral position? (Photo)

Hi Bearbear,Your body's tissue will compress your implants slightly, regardless of which placement you use. Most PS upsize by 25-50 cc over your desired size.  However, you are getting pretty big is you go up to 575 or even 600, so check with your PS directly about your personal dimensional analysis.  Many PS around the world favor the subfascial placement.  Happy Holidays, Dr. Joe

The actual volume of the implant will be identical no matter where it is placed.  The wish pics you posted do show high, round breasts that look obviously augmented, and it appears that the implant outline is visible.   This look might be more achievable if the implants are subfascial since there will be less tissue coverage.  On the other hand, if you are choosing very large implants there will already be an increased risk of visible rippling so putting the implants under the muscle may be a better option because it will provide a little more coverage.  Your plastic surgeon will help you understand the pros and cons of each pocket.

I do  not see any advantage to place implant subfascial. This is basically the same as subglandular.  I prefer submuscular.

     Implant position may affect the appearance and projection of the breast tissue but the overall volume is still the same regardless of the placement(subglandular, subfascial or subpectoral).  The choice for placement is usually determined by the thickness and quality of the overlying upper breast tissue and whether or not there is any drop or ptosis of the breast.  Implants placed under the pectoral muscle may seem slightly smaller due to the compressive effect of the pectoral muscle and will project less for that reason (this problem can be minimized by release of the lower pectoral muscle during surgery).  The fascia of the pectorals is quite thin and should not result in any significant reduction in the appearance of the implant volume.

It is common misinformation that an implant has less volume when placed under the muscle. There is no study that actually measured this and it is really not possible since neither saline nor silicone lose volume when compressed (unlike a sponge which gets smaller with compression). Furthermore, if it was true, it would depend on the amount of muscle coverage (Dual Plane 1, 2, or 3) and also on compression due to skin tightness. Discuss with your surgeon to make sure your implant has proper dimesions for your chest & breast.  

When you place implants under the muscle there is compression of the implant by the muscle.  This gives the implants about 25cc less volume than when implants are placed over your skin,  subglandular or subfascial.  A pinch test will determine if subfascial placement is an appropriate position in your case.  With such large implants you may experience some visibilty or rippling.
