No, you are not too old for arm lift or brachioplasty. Before any surgery is performed, I always order blood tests, EKG and chest x-ray. If all these studies are within normal limits, there is no reason why you should not be allowed to undergo arm surgery. The arm lift or brachioplasty takes approximately two to three hours under general anesthesia. There are a variety of incisions. For you, I would imagine healing would take two to three weeks. Most people are very pleased with their arm lift or brachioplasty results. I hope this answers your question regarding the safety of performing a brachioplasty on a patient who is 78 years old. If you have any questions, please feel free to contact my office. Sincerely, Dr.Katzen
