Is it common for skin glue to be used to close incisions after breast reduction?

Thank you for your question.
Using a skin glue such as dermabond is incredibly common. This is placed over dissolvable sutures to provide another layer and aid in keeping the incision closed. I recommend speaking with your plastic surgeon to discuss your concerns.

It is not common to use "only" skin glue to close breast reduction incisions. However, it is likely that your surgeon utilized dissolvable sutures under the skin, called subcuticular sutures, that were holding the incision together in addition to the skin glue. You would not see these sutures as they would be deep to the skin. Unfortunately, while not common, wound healing issues following breast reduction, on either the horizontal or vertical limb, are fairly common due to the size and shape of the incisions. Thankfully, this typically does not have a large impact on the shape or character of the resulting scars.
