Weird Looking Drain Hole Scar After Breast Reduction? (photo)

Allow further healing time. But a revision may be needed at 6 months post operative. Best to discuss with your surgeon in detail. 

Because all of the loose skin is essentially addressed only through the vertical direction with this technique, there is often the need to bunch or gather residual redundancy of the skin under the breast.  While your surgeon may have used this portion of the wound for drain exit, what you are really seeing is just the way that the closure often looks.  Usually this smooths out over time, but this may take a few months.  If it does not resolve satisfactorily, then a revision may be needed or desired, but this typically is done under local anesthesia.
