What is the difference in SSX-SRX implants? (photo)

At size 34 A, each 100 cc of implant corresponds to 1 cup size change.  580 cc implants weigh over 1 lb each and you will increase to approximately a cup size G.  They will most likely not fit but if they did fit they will eventually descend inferiorly and laterally causing complications.  The difference between implants is irrelevant.  Best Wishes,Gary Horndeski, M.D.

Dear samanthac1994,Breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.Daniel Barrett, MD

The X profile implants are extra projecting. They deliver greater volume and projection for a given device width. This represents the highest available profile.The difference between the 2 is not a function of dimension but rather gel fill. the Natrelle INSPIRA line includes three fill variations of increasing cohesivity. The SRX is the lowest of the three (which is still more cohesive than gels used in the past). The SSX is the Soft Touch variation and represents the middle ground between a form stable "gummy bear" and the traditional INSPIRA.With regards to your specific question, implants will not create cleavage in the sense that they cannot centralize wide or lateral set breasts. The implants will be centered on your native breast mound which may seemingly worsen the wide set nature of the breasts without actually changing the measurements. It is often helpful to think of breast augmentation as a magnifying glass or IMAX screen where all aspects of the breast are enlarged (+) and (-).
One option for creating a more central or medial mound is subglandular augmentation. In this scenario, the medial boundary as defined by the pectoralis muscle attachments to the sternum are not present. This can allow for greater medial dissection and by association greater cleavage (not recommended). However, this does in crease the risk of symmastia. There is also the risk of deformity which stems from failure to center the implant on the native breast mound.
Ultimately, cleavage is essentially a function of the anatomic starting point. If you have wide set breasts, implants are only likely to accentuate this deficit. However, patients with closely spaced breasts will accentuate their cleavage via augmentation. Trying to force the mound centrally often leads to a mismatch between implant and native breast. They must be centered on each other in order to obtain a good result.
When placing the implants submuscular, greater width will not improve cleavage. On the contrary, increasing width and exceeding your specific BWD will lead to a frame mismatch and lateral migration towards the armpit.It is difficult to say for certain whether your chosen implants can deliver the result in your goal photos without your pre-op photos for comparison. The choice of an X implant will deliver greater volume and projection on your smaller frame.The SRX vs. SSX gel variation will yield a slightly firmer implant with less give and more shape (with the SSX).
As always, discuss your concerns with a board certified plastic surgeon (ABPS). 

Thank you for your question. Breast implant sizing and styles can often be confusing to patients. Implant sizing and style depends on the amount of breast tissue the patient has as well as their chest measurements and their desired results. SSX and SRX are different styles of Allergan silicone implants. The X stands for extra full projection. The difference between the two implants is not dimension but rather the gel fill. Which implant is best for you is decided after physical examination and multiple measurements.  I would review the before and after photographs of the surgeons and see which photographs you prefer and discuss the implants used in those. Also bring photographs of breast implants that you find aesthetically pleasing so you and your surgeon can review those and make sure you are on the same page. 
Best regards,

Thank you for the wish photo. SSX and SRX are different styles of Allergan silicone implants. The X stands for extra full projection. The R is the softest implant and the S is a slightly firmer implant. Your wish photo shows large breasts that are positioned close together on a small frame. If you are also small framed, then it is possible that your surgeon is picking an X implant to allow larger implants on your smaller frame. An S will also give a more round full shape than an R particularly under the muscle. Generally speaking an SSX is not an unreasonable style of implant but that alone is not enough information to tell whether it will work to achieve your goal. Picking the right implant requires many measurements and a detailed physical examination to know what will work best. Hope this helps!

The overall dimensions of the two are the same, the cohesivity, or stiffness, of the silicone is more in the ssx vs the srx. The X is extremely high profile and so is the most unnatural looking of all the implants. The discussion of implants for a patient is lengthy and requires a full consultation and examination and all the details will be discussed with you by your surgeon during the consultation. If you want width, you will probably want the M profile, or possible the F depending on the volume you are trying to achieve.
