340-360 CC saline is equivalent to what CC in silicone?

I am 96 lbs, 5’4, 38 years old. I want modest breasts. I wanted 275 CC but my surgeon said 330-360 CC when we discussed saline. But then I decided on silicone and he said 365CC. I don’t want to be a “D” cup.

Bra sizing is extremely difficult to use—different at different stores and different from one change in band size, i.e. 34B is the same volume as a 36A and a 32C. Saline implants don't account for the volume of the shell which is 10-15 cc. I hope this helps. I have found that bringing wish pictures to your consultation helps a lot when trying to determine what size you are both talking about. Good luck!

If you want 275cc implants, find another plastic surgeon for a second opinion. I generally recommend putting an implant of the size you want in your bra at the office and see if that is the look you are going for. Do the same for the larger sizes and see if they are too big. You should be able to get what you want. I once knew a surgeon who did not ask patients and put 300cc implants in every patient—crazy. And cc's in saline are the same as cc's in silicone, though the implants may differ slightly in their dimensions.

CC's is same in silicone or saline and every 120-150cc increase is about 1 cup size.

Both silicone and saline devices are safe and reasonable options.

Patients should be aware of the inherent differences between the available implants.

Saline vs. Silicone differences include:

-The "feel"- silicone is more natural

-The "look"- silicone is less prone to rippling

-The "cost"- silicone is more expensive

-Customization-Silicone implants are pre-filled to a particular volume. Saline can be adjusted on the table within a recommended range.

-Monitoring-Saline implants, if ruptured, will deflate and the saline fill will be absorbed. Silicone implants require surveillance MRI's at 3 years and every 2 years after.

-Incisions- Because saline implants are placed empty they can be passed through slightly smaller incisions

With regards to volume, saline and silicone are equivalent. While there is a difference in the final appearance, it is not necessarily an issue of volume but more likely projection.

I would try not to focus on a particular cup size as this can be variable and instead focus on the look you are trying to achieve. This will help guide you through the implant selection process.

As always, discuss your concerns with a board certified plastic surgeon (ABPS).

Generally saline implants tend to project more or achieve a fuller look than silicone implants of the same number of CCs. Therefore, if choosing silicone over saline primarily or if replacing saline implants with silicone it is usually necessary to select a higher volume (more CCs) implant...typically at least 20% more to achieve a similar size result.

My partner just had a breast augmentation. She wanted bigger breasts and went from 450cc's to 520cc's. She is 36" in the chest, 5'3" tall and a size 12 (curvy). What cup size will she be? I love my girlfriend dearly and didn't want her to go through with the surgery, but she insisted. She wants to be a F or G cup.

I have not gone for a consult at all, but have always wanted a breast augmentation/enlargement for the last 12-14 years. I want to know what I can use in order to try out the right size at home and possibly around town to make sure I am looking to the right size when I go for the consult. Also, I am looking for a detailed number of CCs that would get me to that size. .

Hi, I heard that Motiva ergonomix implants are better than other implants brands/smooth or textured type. Is it true? I'm so confused due to lots of advertisement on the internet and somewhat short of real reviews. (FYI, I'm an Asian.) I would be grateful if you could give me some advice on this. Thanks in advance!

I had a breast augmentation (implants) 5 years ago. One of my breasts has always hurt, and now it is starting to get a flap/droop towards the inside of that breast. This drooping breast has a red mark where the flap is, and it hurts. My doctor claims it is due to gravity. Is this true? What could be causing the pain?

I had a breast augmentation and lift June 20. My left breast looks lower but dr ignores my concern. However, I went in three days ago, and the redness and now pain on left side continues. He put me on Keflex 500 mg, 4 times a day for 10 days. My right side feels better, but something is still wrong with the left. I go back in a week, but am getting more worried. Also, I still need Percocet to sleep. What's going on? Is my doc doing all that he can to help me?

I am four weeks post op and see my surgeon for my follow up tomorrow. My breasts look 100% better! But they look good, not great. They are not what I expected and not what I was made to think they would be. I don’t want to upset the surgeon but to go through all of this and pay this much money and not be happy... I started my journey with VSG. After losing the weight my breasts had deflated! So I had a reduction, lift and implants. We kept going over the “fullness at the top” and it’s not there.

It’s been two years since breast enhancement surgery, and my right boob fell today. I’m not in pain, and I did not feel it happen. That breast still has the fold/crease underneath, but it’s 1.5 inches lower than my left, feels flatter, and is not as tight. How much does a crease fix cost?
