Hi PR. I wanted to say that Dr. Goldstein's answer to your question is important to consider. There are many causes for bulging in the upper abdomen after a tummy-tuck. It might be because the upper abdominal tissue was not cinched together tightly and the lower abdominal tissue was cinched more tightly together. This is well known to cause a bulge in the upper abdomen.
In your case, you mention that a suture broke. This is a very rare occurrence and only you and your plastic surgeon know the circumstances around being able to detect a broken suture. If you truly had a flat upper abdomen one minute, heard a suture break, then had a bulge, then you will likely need to have your tummy-tuck revised and the stitch replaced.
If the suture did break and you go ahead with liposuction, then you are in danger of causing damage to internal organs during liposuction. It is possible to be very cautious and thin the fat just under the skin, but if the suture was truly broken, then it would NOT be recommended. Have some more conversations with your plastic surgeon. Certainly waiting for 6 months before doing a revision is what I would recommend.
