The upper arms are a challenging area for liposuction, as the skin in that area has less elasticity and is more prone to being loose after the underlying fat is removed. Contour irregularities, as you're experiencing, can also occur and are more common when technologies involving heat energy are used to try to encourage the overlying skin to shrink (e.g. laser liposuction or SmartLipo). I would not consider a revision procedure for at least 6 months after your original surgery. If it has been at least 6 months since your procedure, I would consider an arm lift during which loose skin is removed. The scar for this procedure is usually placed on the inner arm between the biceps muscle and triceps muscle. I disagree with one of the other surgeons that responded in that the arm lift scar tends to be one of the more disappointing scars in terms of its appearance. While this scar can be thin, flat, and inconspicuous, it is not uncommon for it to be wide and a little raised, particularly close to the elbow. I caution my patients that they have to be willing to accept this scar for the improvement in the shape and you may not feel that the trade-off is worthwhile. There is a "mini" arm lift that limits the scar to the armpit. The improvement in shape with that version of the procedure tends to be "mini" as well, but if you're not willing to accept the more extensive scar you could discuss the mini option with your surgeon also.
