Persistent facial swelling after acne subcision?

Question

38 years old man, underwent bilateral acne scar subcision using Nokor needle. There is significant improvement in acne scars, however after about 6 months, there are 2 cyst like non-tender, non-erythematous soft swelling on both buccal areas with the size of 4x4 cm. Looks like some fluid filled cysts, however aspiration does not return any fluid or blood. No US or MRI is done. 1. What would be the diagnosis? 2. What should be the next step? 3. What would be the treatment?

I suggest posting photos or seeing an acne scarring/laser specialist.  This may need steroid injections or radiofrequency/laser treatments.  There are options for this type of issue.  Best, Dr. Emer.

Swelling should not be prolonged after subcision. In some cases, we recommend antibiotics if swelling persists and perhaps a Medrol dose pack. Best, Dr. Karamanoukian Los Angeles

You were correct to mention US and MRI/CT as the next steps in the process.  I would also repeat the cultures to ascertain if an infection was missed.  Please keep us posted. The scars can eventually be treated with lasers. Best, Dr. Green

I had a similar case 6 weeks ago. Persistent swelling 2 months post subcision, settled with 2 weak - dilute A5 triamcinolone CS injections. Given your case, I would suggest an USS, for my case I tried aspiration as without success. My theory is that that may represent an organised haematoma.
