Hi CanIgetSomehelp,
I read with interest some of the answers given to the question you posed. There in fact may not be a study out there that compares the two methods of breast lifting as to their longevity. That may not be possible to do. There is so much variability between patients and surgeons that large numbers would be required to have any statistical significance. The only other way to compare the two is to perform a skin lift on one side and an internal lift on the other. There actually was a study like that comparing face lift procedures but their conclusions were questionable. Therefore, I think we have to use other modes of reasoning to answer your question.
Firstly, It is well recognized that when plastic surgeons close an open wound, it is preferable to close the fascial layer under the skin for strength and support. This is done in traumatic wounds but also in cosmetic procedures such as tummy tucks, thigh lifts, arm lifts, etc. Without that fascial support there is a high chance of wound separation, poor scarring, and stretching. This is irrefutable. The breast, too, has a fascial framework. The same principles should hold here as well. Placing sutures in this fascial framework of the breast should lend additional support. Secondly, one needs to realize, that when placing sutures within the breast tissue, the skin is sutured as well. That is, an internal lift is a skin lift in addition to the internal support. To make the argument that a skin lift is as good as an internal lift is to argue that internal sutures add nothing to the support. That flies against logic and goes against all other principles of repair. Finally, I have my own experiences to compare. I was trained doing skin lifts only. Early in my private practice the vertical mammaplasty became popular. That is a breast lift technique that uses internal shaping and suturing. I have been using that technique along with my own modification since the mid 90's. In my opinion, the vertical mammaplasty is superior to the skin only lift in many ways. It produces a better shape. It produces exceptional scars. It can avoid the horizontal incision. And in my opinion it definitely stays higher for a longer period of time.
That being said, I don't believe you need to fear that your lift is doomed to fail if you had a skin only lift. Just because you had an anchor incision that does not imply that you had a skin only lift. Also, some patients do quite well with regardless of which technique is used.
Good luck,
