Also called arm tuck surgery, this surgery decreases the annular area of the upper arm, particularly in patients with severe obesity. Considering the obvious laxity or droopiness due to long-term fat deposits at the arm, liposuction aggravates skin looseness, so arm fats and partial loose skin should be concurrently resected to achieve the dual results of arm slimming and skin tightening. The surgery is conducted by making a 15–20-cm incision from the armpit to the medial side of the elbow joint to concurrently remove the posterior one-half region of the loose skin and fats before stitching the wound. Despite the results being significant, this surgery is less frequently performed for the correction of arm fats as oriental females are usually not as obese as Westerners. Moreover, Dr. Chuang reminds that the surgical incision is generally long and obvious, so patients should take into account the individual constitution and acceptability of scars and care about the wound to avoid scar proliferation or contraction.
