Does Fat Necrosis Cause Thigh Dents?

You can have fat necrosis in or on any part of the body that contains fat. It is frequently seen on the breasts as a complication of breast surgery. The literal meaning of fat necrosis is fat death. The dying fat may forms a lump that may resolve with time or may need to be removed. When fat is removed or destroyed, it doesn’t grow back in the affected area. A dent is the result. Filling in depressions or dents are plastic surgery procedures, and quite common ones.

Dents in Fat

Dents in fatty tissue can be the eventual result of fat necrosis or of intentional fat removal. Liposuction can result in dents. These sometimes will be improved by touch-up liposuction. Liposuction dents that do not respond, as well as dents from fat necrosis or other causes, can be filled in by fat grafting. Fat grafting is also referred to as fat injection. This is done using your own fat, so there is little chance of tissue rejection.

Fat Grafting

Fat grafting requires that you have an area of fatty tissue where the removal of a sufficient quantity will not cause yet another cosmetic defect. The abdomen, buttocks or thighs are often the sites chosen. Since some of the fat transferred by grafting will not survive, it’s necessary to overfill the dent. The surviving fat cells will fill the dent and draw nourishment from the blood as it did in its original location.


The exact procedure used will depend on the amount of fat to be transferred. In direct terms, fat is drawn out by syringe or liposuction instruments and injected by syringe into the area with the dent. Your plastic surgeon will want to be sure the area has good circulation as fat necrosis is sometimes due to insufficient blood supply. For most dents, this will be an outpatient procedure with a short recuperation time. It is essential to follow the instructions for aftercare and follow up to assure the best results.

Financial Considerations

Fat grafting can be a good solution to a dent in the thigh. However, you do need to check your medical insurance. Fat grafting is usually considered a cosmetic procedure and not covered by most insurance. This means that you will have to pay a plastic surgeon for the procedure before it is done. Most plastic surgeons offer a free consultation for cosmetic procedures so you will be aware of the risks, benefits and costs. Be sure to ask your plastic surgeon’s office for details on payment options. They may be able to direct you to a low interest or even interest free credit card.
