Hi Chalani, Thank you for your question regarding a seroma that developed after your arm lift. After arm surgery like an arm lift, seromas are a rare complication. However, arm seromas do occur. I would suggest needle aspiration. This procedure is performed in the office. The skin around the seroma is anesthetized (made numb). A needle is then inserted, and the fluid inside the seroma is drained. Sometimes a sclerotic is injected into the seroma. A sclerotic is a substance that reacts with the wall of the seroma and causes the seroma to shrink and collapse. Most arm seromas disappear after 3 to 4 aspirations with a needle. Stubborn arm seromas require surgical drainage. This procedure can also be performed in the office. The arm skin is anesthetized, and small 1inch incision is made. A Penrose drain is placed. A Penrose drain is a passive drain, which means it is not on suction. Suction drains may prolong a seroma. Typically, after 7 to 10 days, the seroma “has burned out” and the drain can be removed. Good luck. If you have any other questions in regards to an arm seroma or arm lifts in general, please contact my office. Sincerely, Dr. J. Timothy Katzen
