Is liposuction possible on a fat pad above the buttock area? (photos)

Yes, based on your pictures, it looks like this area could be easily treated with liposuction. For small areas of liposuction like this, I give patients an option to have the procedure done awake. Patient are generally quite comfortably with just local numbing medicine. This also speeds recovery and eliminates the additional cost of anesthesia.Emile Brown, MDBoard Certified Plastic Surgeon, Johns Hopkins & Harvard Trained

You could get liposuction to the entire flank / lower back area and it would likely even and smooth it out. It would be expensive to just liposuction that one section and the results would likely be very uneven if the surgeon tried to remove the fat deposit alone.  Always be sure to get a consult with a board certified plastic surgeon in your area for the best results.

Hi, thank you for your question. 
The short answer is yes, liposuction can likely be used to treat this area. The best way to determine if it can definitely be used would be through an in-person consultation with your plastic surgeon. 
In order to have the best results with liposuction, you would need to be healthy enough for elective surgery, maintaining a stable weight for 3 months, refrain from smoking for at least 4 weeks and maintain a BMI of 30. 
I hope this helps. Best of luck!
