Thank you for your question about whether this is loose skin and whether a thigh lift revision is necessary. Thank you for your history and your pictures. Congratulations on your massive weight loss of 120 pounds. In examining your pictures, you previously had a crescent, a hidden, or a mini thigh lift. During a crescent thigh lift, excess skin and fat in the upper inner third of the thigh are removed. The crescent thigh lift has a high complication rate of wound breakdown, not enough skin being removed, labial spread, and opening to the introitus (opening to the vagina). There is also a high risk of the scar spreading or migrating down the inner thigh due to tension in the incision and gravity. Most plastic surgeons would agree that your incision was not too low. It is more likely that the crescent thigh lift scar has migrated. In terms of revision, you do not need another crescent thigh lift. You have excess skin and fat from the groin to the upper portion of the knee. A crescent thigh lift will not address this area of inner thigh skin and fat. This area of skin needs to be addressed with a thigh lift. You either need a modified or complete longitudinal, vertical medial thigh lift with an incision from the groin, either partially down the inner thigh or completely to the knee. If the excess skin and fat of the inner knee area does not bother you, you only need an incision from the groin partially down the inner thigh. If the scar is too visible for you, do not consider a thigh lift. However, be forewarned that another crescent or mini thigh lift revision will not remove much more skin. Good luck. I hope I’ve answered your question about whether you have loose thigh skin and whether a thigh lift revision surgery is necessary. I hope that I have answered your questions regarding the thigh reduction. If you have any more questions regarding the thigh lift, thigh reduction, vertical thigh lift, medial thigh lift, spiral thigh lift, crescent thigh lift, or thigh lipo, contact an experienced plastic surgeon. Please seek an experienced, board-certified plastic surgeon with significant experience performing thigh lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 thigh lifts. Make sure they have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen, MD, MBA.
