Many surgeons do not perform TUBA for a variety of reasons. It is not uncommon to see ridges/irregularities in the upper abdomen as the process of getting up to the breast to make the pocket requires passage of a tubular structure using a blind technique that pushes through the tissue to make a pathway. This can obviously lead to irregularity or a hollow tunnel in the fat, which can result in ridges. You might have some improvement with liposuction, possibly in combination with some fat grafting to the ridged areas (not a very precise technique, to be honest) to get some improvement. I took the training course from the inventor of the TUBA technique and have to say I had significant reservations about its safety and predictability as a technique, so I decided against offering it, especially when inframammary incisions can fade very nicely when properly placed, and when we now know that capsular contracture rates are higher with periareolar incisions from a risk standpoint.
