Arm lift in February 2016 and a revision that was suppose to include liposuction in oct 2016. (photos)

Brachioplasty scars can be very hard to achieve a nice fine line scar due to a variety of factors. So nice your last revision was in October I would wait for the scar to soften and become less thick before considering anything surgical. You can have your surgeon inject some steroids or laser the scar in the mean time to help 

I'm sorry to hear about your experience. I believe you will need a two step revision approach. In the first surgery, I would likely only recommend liposuction to the arms. I would then compress for 6 months and then return to perform skin removal with complete scar revision. More compression  (3 months) can be performed after the scar procedure. The banding will likely improve, but may not fully resolve.
This should be followed by 8 to 12 weeks of scar therapy with Embrace Scar Defense. 
Find a board certified plastic surgeon for a second opinion in your area.

Congratulations on having undergone an arm lift or brachioplasty.  Currently, you are only four months from your arm lift revision. I would wait at least another two months before you do anything. In the meantime, I would suggest silicone cream, silicone tape, and continuing arm compression garments. In addition, you may want to consider laser treatment to the arm scar or even a derma pen.  To determine if arm liposuction was performed during your arm lift or arm reduction (brachioplasty), please request for a copy of your operative report. In regards to the arm band, it is difficult to tell. If this arm band was present before your surgery, this can be difficult to treat. I believe this is arm band is a genetic or congenital condition. If this arm band was there before you had surgery, this arm band can be treated with very selective arm liposuction performed on each side of the arm band.  If the arm band resulted after the arm lift surgery, then the arm band and scar may need to be released. This arm band and scar release can be difficult to perform and made make the scar more noticeable. What may be  needed is what is called a z-plasty. To release the arm band and scar, a zigzag incision is made. Tissues are rearranged and release the tension in the arm band or scar tissue.  The arm z-plasty works very well, however, the arm z-plasty may make for arm scars more noticeable. I hope this answers your question regarding your arm lift results and the possible need for rebision.  For now, I would sit tight and do the conservative treatments mentioned above.  In two months, I would revisit with your board-certified plastic surgeon and discuss possible revisions.  Good luck! If you have any further questions regarding the arm lift, brachioplasty, arm reduction, arm liposuction, arm liposculpting, arm scar revision, or arm banding after an arm lift, please contact my office.
