Hello, thank you for your question regarding a thigh lift. I specialize in thigh lifts. First, thigh lift are not really thigh lifts, they are more thigh reductions with a thigh lift that comes during the thigh reduction. however, we are stuck with the phrase "thigh lift". Anyways, basically, there are seven types of thigh lifts: crescent, vertical, modified vertical, T, modified T, spiral and the lateral thigh lift. During a crescent thigh lift, an incision is made high in the groin--where the upper thigh meets the groin. The upper, inner thigh is pulled upward. A crescent area of upper, inner thigh skin and fat is removed. During a vertical thigh lift, liposuction is performed and an incision is made from the groin to the knee. The inner thigh is pulled together in a vertical fashion like closing the curtains (not pulling the blind down, though). An elliptical area of medial or inner thigh skin and fat is removed. During a modified vertical thigh lift, the incision does not go completely to the knee. Only the upper inner thigh is involved. This is ideal for patients who have "normal" knees. The "T" thigh lift combines the crescent thigh and the vertical thigh lift. During the "T" thigh lift, a "T" shaped area of inner thigh skin is removed. The final scar is also in the shape of the letter "T". The "modified T" thigh lift combines the crescent thigh lift with the modified vertical thigh lift. During the spiral thigh lift, the buttocks are involved. During a lateral thigh lift, an incision is made on the outer (not inner) thigh and extends from the top of the hip to the outer knee. An elliptical area of outer thigh skin is removed. All thigh lifts are performed under general anesthesia. Recovery from a thigh lift is about three to four weeks. In regards to your questions about inner thigh scar migration, this is more common during the crescent thigh lift, T, or modified T. Scar migration is rare during the vertical thigh lift. Inner thigh scars migrate because the weight and tension of the upper, inner thigh pulls on the groin scar. If the inner thigh scar pulls too much, the vulva or opening to the vagina can spread open. NOT GOOD!! One way to avoid this is to secure the upper, inner thigh to the pelvic bone and fascia. I have developed and presented this inner thigh anchoring technique in several conferences. Once the tension has been transferred to the pelvic bone, the upper, inner thigh scar cannot spread. In regards to inner thigh scars getting wider and larger, this is rare. To achieve almost invisible thigh scars, the thigh must be closed in multiple layers with very specific suture types. There must be minimal tension. Wounds sometimes do occur. When wounds occur, they are mostly due to the thigh lymphatic system. Initially, the thigh lift scars may be lumpy, but over time, the lumps become smooth. In regards to the fact that you have "never seen a healed picture of (thigh) scars because they're covered by garments and closed legs!)". Well, I am happy to say, please visit my website. I am very proud to say, in almost all my before and after patient pictures, the patients are naked allowing the scar to be seen. However, in plastic surgeons' defense, you do not want to be able to see the inner thigh lift when someone is facing you; everyone wants the thigh lift scar hidden. It is my firm belief that post-operative scars must and should be shown to a prospective patient. And "yes", all thigh scars do fade and flatten. They will never disappear, but usually the scars are much better than having big thighs. I hope this helps you in your quest for a thigh lift. Please remember the thigh lift is not an easy surgery, and should be performed by an experienced plastic surgeon. I hope that I have answered your questions about the different types of thigh lifts and the potential complications, such a scar migration. If you have any more questions regarding the thigh lift, please contact my office.
