How much fat should be liposuctioned to get 200cc of pure fat?

Although this is a great question, there is not an exact answer to this question. I find that in athletic thin patients, close to twice as much fat must be obtained to have the amount wanted for transfer. So, in your case, obtaining about 400 cc of total fat will typically yield 200 cc of "pure" fat. These numbers vary though. Sometimes 300 cc total can yield 200 cc. It's up to the surgeon to make the determination on the amount of areas to be addressed to obtain an amount that will result in enough fat to transfer.

Thank you for your question. To provide a valid medical opinion I will need to see pictures of you body from different angles. I would suggest to be treated by board certified plastic surgeon with experience in this procedure, to get the best desired results.

Sounds like the surgeon who you selected told you how much they wanted to suction and if they offered you the procedure it sounds like they feel like they can achieve what you are looking for and they are offering. If you dont trust them I would get a second opinion or not go with them for the procedure.

Depending of the technique used for fat harvest/liposuction, fat content (supernatant fat) should be 70% and more of the aspirated volume. This should be best discussed with your surgeon, based on specific technique he uses for fat harvest. Good luck.

The actual volume removed is dependent upon how much fluid is used to pretreat the area. Your surgeon will aspirate until he/she gets at least 200 cc's of fat.

To remove 200 mL of fat the surgeon will stop when the canister reads 200 mL. The aspirate that is removed from Liposuction contains some water which will be at the bottom of the container and it’s pretty simple to simply calculate the total volume minus the water part equals the amount of fat in the container. Fat grafting for a procedure like you describe not require an exact 200 mL of fat. The surgeon may use less or may use more but it’s always good to have enough fat to finish the procedure.
You didn’t include pictures but my biggest concern is that fat grafting will not work for your condition.
Whenever I’ve seen cases of indentations due to childhood injections it’s always scar tissue pulling down the skin and not a lack of fat.For that reason the contour regularity is more like cellulite and can be made worse from fat transfer rather than better.
I suggest you have the surgeon work with fillers on one spot to see if volume restoration will even make an improvement. What you describe doesn’t sound like it’s going to be a successful outcome but you didn’t include pictures and my opinion and experience is just that my opinion and my experience.
There are lots of things other surgeons can do that I can’t and I’m sure there’s many who know things I don’t know.
Did the doctor show you before and after pictures of other patients who had this done successfully?
The condition you describe does not sound like it’s due to a lack of subcutaneous fat.
Consider getting a couple of second opinions before having surgery.

Hi and welcome to our forum!During performance of liposuction, one can measure the percentage of fat being aspirated compared to the total volume of aspirate (the so-called "fatocrit"). The aspirate also contains blood and by products. If this percentage drops below 50%, the surgeon should cease liposuction in that area to avoid over-suctioning. Thus at least 200 cc of fat can usually be harvested from 400 cc of aspirate.Best wishes...
