Introduction: The use of quilting suture in the abdominal flap, fixing it to the aponeurosis and the use of progressive tension suture were incontestable technical advances in order to prevent seroma in abdominoplasties. Moreover, this sutures act distributing the flap tension over the undermined area of the subcutaneous tissue, what, in theory, reduces the traction in the cutaneous end of the abdominal flap. This fact would reduce the risk of necrosis, dehiscence, enlarged and hypertrophic scars. The objective of this study is to evaluate if the quilting suture reduces the traction on the skin closure in abdominoplasties. Method: Thirty four patients who underwent abdominoplasty with quilting suture were evaluated. The skin closure traction was measured with a digital dynamometer before and after the quilting suture, in order to assess the decrease in tension after it. The correlation between BMI, patients’ age, flaps weight and number of pregnancies with reduction of the flap traction was evaluated. Complications as seroma, hematoma, necrosis, dehiscence, enlarged and hypertrophic scars were also evaluated. Results: We observed a mean reduction of 27.36% in the skin closure traction after the quilting suture of the flap to the aponeurosis. There was no significant relation between BMI, patients’ age, flaps weight and number of pregnancies with reduction of the flap traction. There was one seroma, two enlarged scars, no hematoma, necrosis or scar dehiscence. Conclusion: The quilting suture of the flap to the anterior abdominal wall aponeurosis contributes to the reduction of skin traction when moving down the abdominal flap in abdominoplasties.
