This is impossible for me to answer except on an individual basis. For my patients, it depends totally upon the amount of drainage. I use two drains except in thinner patients with very little associated liposuction, when I use only one. For others, the length of time it take to remove the last drain (the first one comes out in 5-7 days), is a function of two major factors.First and foremost is the amount of associated abdominal and flank liposuction performed simultaneously. I am very aggressive with suction along with tummy tucks. It helps eliminate the "dog ear" issue you may have read about. But liposuction is also the most important factor in reducing your overall size during the procedure. Therefore, the more size reduction via suction, the longer you will drain fluid. Secondly, a large separation of the muscle, tightened at the time of the tuck, will increase the time of drainage. This is an important part of the surgery to say the least. The bottom line is, the second drain comes out when it is ready. Five to seven days in thinner patients, two weeks or even longer in very large patients with more extensive procedures. When leaving drains for longer periods, I use small doses of antibiotics to prevent infection and have never had issues with infection. The good news for the larger patients with longer drain times is that the drain can be hidden easily and return to activity time is rarely affected.
