Difference between scar tissue and residual gland post gynecomastia?

Scar tissue will have a completely different look to healthy tissues or other glands when viewed with an ultrasound. If indeed these scar tissues are under your skin, then 2-3 months after surgery is a reasonable enough time to consider cortisone injection if the scar tissue is excessive.

Thank you for your question. Sometimes, in the early postoperativ period,  there may be a firm area just below the areola which could be related to fluid and blood that have collected in the space left by removal of the gland. This will usually improve over a 4 to 6 month period of time. Even on ultrasound, it's sometimes difficult to tell organizing scar tissue from residual gland. I would give it some time. Should it not get smaller over the next few months, then a re-excision may be necessary. Hope that's helpfu
