The back is vulnerable to refractory fat deposits, which results in many females suffering from the disturbance of a “stocky build,” and losing weight hardly achieves a distinct improvement. Therefore, liposuction is considered to be the most effective method to correct the problem. Because most fats accumulated on the back region are surficial fat globules closely adhering to the skin, traditional mechanical liposuction does not work effectively but rather likely causes uneven skin. Therefore, Dr. Chuang currently applies Ultra-Z lipolysis to emulsify and lyse the hard fat globules by high-frequency ultrasonic waves and then utilizes various lengths and sizes of liposuction tubes to suction out the fats. Besides being able to achieve results traditional liposuction fails to achieve by the effective lysis and suction of superficial fats, this surgery avoids skin unevenness due to the excess damage of subcutaneous tissues and is thus the safest and most effective liposuction method.

As the back extends from the lateral side of the scapula posterior to the arm to the upper margin of the posterior waist, the site of liposuction needs to be determined based on patient’s requirements and conditions. The surgery is conducted by making a 0.5-cm incision at both sides of the back and by perfusing hemostatics and painkillers under the skin first. Then, Dr. Chuang introduces a high-frequency ultrasonic lipolysis probe into the skin to dissolve and emulsify superficial fats and suctions liquefied fat globules with the assistance of a liposuction machine. Because subcutaneous fats at the back are relatively few, suctioning 200–300 cc of fats on average presents obvious effects.

This surgery does not remove large amounts of fats but rather suctions out superficial fats whose amount cannot be reduced by weight loss to make the back curvature slimmer and mitigate cellulite deposits due to cloth compression. If the fat deposits are relatively mild, a non-surgical lipodissolve injection is given in approximately 2–3 sessions for the regional obese parts. Although the treatment lasts for relatively a long time, it finally renders distinct fat removal.
