Hi ChabeL in Rancho Cucamonga, CA, Thank you for your question regarding whether a posterior thigh lift will remove excess skin under the butt crease. Thank you for your history and pictures. Let’s analyze your pictures. Based on your pictures, especially the posterior and side profiles, you have excess skin and fat in the infra-gluteal fold. The infra-gluteal fold is also called the banana roll. If you only do liposuction on the banana roll, you will be left with excess skin in the posterior thigh. Therefore, a better surgery than isolated banana roll liposuction would be to remove both skin and fat in the intragluteal fold. To achieve this, an incision is placed underneath the buttock. The incision is placed where the buttock meets the posterior thigh. From this incision, tissue dissection is carried down the back of the posterior thigh. A crescent-shaped area of skin and fat is taken from the posterior, inner thigh. The osterior crescent thigh lift is also called a crescent thigh lift or a spiral thigh lift. A thigh lift is also called a thigplasty. Again, thigh liposuction alone will not achieve these results, as you have an infra-gluteal skin and fat “tissue issue.” To get an accurate assessment of what exactly you need, schedule a free virtual consultation. Most plastic surgeons offer free virtual consultations. I hope that I have answered your questions regarding the thigh reduction. More specifically, I hope I have answered your question about whether a posterior thigh lift will remove excess skin under the butt crease. 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.
