How many liters for a touch-up lipo/thigh lift 6 months after 360 debulking surgery?

For a touch up, you may be under one liter of fat. Your surgeon who has examined you will be the only one who can estimate how much fat might be removed.

There is no yes or no type answer to your question.
Each surgeon will have their own view on what appropriate and what’s not.
It also depends on each individual patient.
Generally speaking, most plastic surgeons will not do high volume liposuction in conjunction with Skin procedures, like a thigh lift.
If obesity is the primary problem, then perhaps that should be addressed as the primary problem rather than having Liposuction.
Without pictures, we can’t begin to make an assessment.
If you have a provider, then forward your questions to him or her.
If you don’t have a provider, then start the process by scheduling multiple in person consultations with board-certified plastic surgeons in your community who have experience with these procedures.
Best,
