Thank you for the question. Tailor tacking is an important part of the mastopexy and mastopexy/augmentation procedure. It involves TEMPORARY closure of the skin (for example with temporary skin staples) to double check the amount of skin that is to be excised during the procedure. This maneuver is done to ensure that enough skin, but not too much, is removed. On the one hand, it is important that enough skin be removed to achieve the aesthetic breast lifting results the patient is looking for; on the other hand, is important not to move too much skin creating tension upon closure and potential wide scars. The tailor tacking technique is very important when performing breast augmentation/mastopexy procedures. Again, this technique allows for a double check of the skin excision prior to the actual excision being carried out. In this procedure (breast augmentation/mastopexy) if too much skin is removed it will limit the size of implant that can be used and/or the surgeon may experience tension upon closure of the skin resulting in wide scars, wounds healing problems, and/or implant exposure. On the other hand, when performing breast augmentation/mastopexy surgery, if too little skin is removed the patient will be left with loose skin and may be dissatisfied with the end result achieved. This loose skin may need to be excised at a later date. You should also be aware that the complications discussed above can occur despite using the tailor tacking technique leading some surgeons to prefer a two-stage breast augmentation mastopexy procedure.The combination breast augmentation / mastopexy surgery differs from breast augmentation surgery alone in that it carries increased risk compared to either breast augmentation or mastopexy surgery performed separately. Furthermore, the potential need for revisionary surgery is increase with breast augmentation / mastopexy surgery done at the same time. In my opinion, the decision to do the operation in a single or two staged fashion becomes a judgment call made by a surgeon after direct examination of the patient. For me, if I see a patient who needs a great degree of lifting, who has lost a lot of skin elasticity, or whose goal is a very large augmentation then I think it is best to do the procedures in 2 stages (in order to avoid serious complications). However, doing the procedure one stage does increase the risks of complications in general and the potential need for further surgery. This increased risk must be weighed against the practical benefits of a single stage procedure (which most patients would prefer). Conversely, if I see a patient who requires minimal to moderate lifting along with a small to moderate size augmentation (and has good skin quality), then doing the procedure one stage is much safer. Nevertheless, the potential risks are greater with a 1 stage procedure and the patient does have a higher likelihood of needing revisionary surgery. I hope this helps.
