Accounting for a large body surface area, the thighs are always the first priority to be improved for many females since they are most likely to accumulate excess fats. Because thigh fats are mostly deep fats, as long as the skin is thicker than 2 cm, liposuction is conducted to achieve distinct improvement. Based on the site of fat deposits, the surgery is divided into regional liposuction (mainly the medial or lateral parts of the thigh) and annular liposuction (around the entire thigh). If necessary, the liposuction extends to the lateral buttocks at the superior lateral part of the thigh or the medial lateral knee. Although the field of thigh liposuction is very flexible, attention should be paid to avoid excess liposuction at the anterior or lateral inferior side of the thigh to prevent postoperative skin depression or an obvious muscular texture.
This surgery is performed by making a 1-cm incision at the anterior groin and posterior gluteal fold. After injecting hemostatics and painkillers into liposuction sites, Dr. Chuang uses Ultra-Z lipolysis to emulsify superficial and deep fats and introduces liposuction tubes of various lengths and sizes into the subcutaneous area to remove lysed fat globules all around the thighs. This method not only effectively increases the volume of fats removed but also prevents the risks of skin unevenness or irregularities. If necessary, it can be conducted with gluteal fold liposuction to sculpt a smiling line between the thigh and buttock. Clinically, the liposuction volume at the thighs is much larger than that at other body parts. Annular liposuction of both thighs removes 2500–3000 cc of fats on an average, which is a relatively large-volume liposuction. Therefore, patients should stay in the hospital for 3–4 h of observation before returning home to rest. All patients should wear a compression garment for over 3 months to ensure skin smoothness and tightness, thus achieving the ultimate result of leg sculpting.
