Posterior Thigh Lift After Liposuction?

It's definitely possible to perform a posterior thigh lift through incisions placed along the buttock crease. Unfortunately, this procedure is associated with unsightly scars that tend to spread and migrate in an inferior direction. For this reason, this procedure is rarely indicated.In your particular case, it's difficult to make recommendations without pictures or a physical examination. In light of the fact that you've already had thigh liposuction and continue to have problems with your posterior thighs, this procedure may offer some value. Under these circumstances, redundant thigh skin can be removed and the thigh lifted in an upward direction. The benefits of this maneuver must be weighed against the high probability of scarring.It's important to realize that no two patients are ever exactly the same. For this reason, it's important to tailor procedures to meet the patient's specific needs. Under these circumstances, excision of skin at the junction of the thigh and buttock may be occasionally indicated.If you're considering this type of procedure, it's important to consult a board certified plastic surgeon with experience in this area. This surgeon should be able to formulate a treatment plan that addresses your anatomic deformity and achieves your aesthetic goals.

Dear Sugarplummy:

Typical thigh lifts are done through an incision in the groin or an incision from the groin to the inner knee. 
Sometimes the incision is also placed on the lateral portion of the leg.  It is possible to place an incision in the inferior portion of the buttock to get rid of excess skin and fat in the upper medial thigh. 
The scar is best hidden in the buttock.  It get rids of approximately four to six inches of skin but not too much more.  It is more geared towards removal of the banana roll of excess skin and fat than a true posterior thigh lift. 
A better surgery for excess skin and fat on the posterior aspect of the thigh lift is to do an extensive medial thigh lift with a significant amount of undermining to pull the posterior skin inward and reduce it also with liposuction.
Congratulations on your weight loss surgery.

The problem that you describe is quite common. In my practice, I call it the "Del Mar Butt Tuck". This removes the redundant extra tissue along the bottom of the buttocks via an incision in the crease. The patients are extremely happy with the results, and the incisions heal very nicely.
