Background: The umbilicus is a key aesthetic unit of the abdominal wall. It contributes to the natural curvature of the abdomen and is now considered as one of the most important factors in the overall results and patient satisfaction. In this study, we present an inverted-U incisional technique for umbilicoplasty. This study aims to describe the senior author's approach to umbilicoplasty and compare the aesthetic outcomes of the inverted-U method with those of the vertical oval incisional technique., Methods: In this retrospective cohort study, we analyzed a total of 109 patients including 51 who underwent umbilicoplasty with the inverted-U incisional technique and 58 who had surgery with the vertical oval incisional method. With the description of our operative technique, the aesthetic outcomes of both techniques were compared by two independent surgeons using a 5-point Likert scale in terms of shape, size, depth, natural appearance and periumbilical scarring. Also, the total scores of the five items were calculated to give a final score for each patient (range, from 5 to 25 points)., Results: On all measured parameters, the inverted-U incisional technique produced favorable outcomes compared with the vertical oval incisional technique. Also, the inverted-U incisional technique was given significantly higher total scores than was the vertical oval incisional technique (inverted-U 14.73 ± 2.47 vs. vertical oval 11.26 ± 3.02, p = 0.002)., Conclusions: In this study, an inverted-U incisional technique produced significantly favorable outcomes in terms of shape, size, depth, natural appearance and overall score compared to a vertical oval incision (p < 0.05). We believe that this technique enables surgeons to achieve a better shape, natural retrusive appearance and superior hood., Level of Evidence Iii: In this study, an inverted-U incisional technique produced significantly favorable outcomes in terms of shape, size, depth, natural appearance and overall score compared to a vertical oval incision (p < 0.05). We believe that this technique enables surgeons to achieve a better shape, natural retrusive appearance and superior hood.

Background: A previous abdominal scar is generally considered as a challenge for breast reconstruction using abdominal flaps. Since it may interfere with the perfusion of abdominal tissue and weaken the abdominal fascia, many plastic surgeons are concerned about the theoretical risk of postoperative complications. This study aims to assess the effects of previous scar on complications in abdominal flap-based breast reconstruction., Methods: This systematic review of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline using MEDLINE, Ovid, and Cochrane databases in March 2020. All studies comparing the complication rates between patients with previous abdominal scars and control group without a scar were included. However, articles such as case series fewer than 10 patients, letters and animal studies were excluded., Results: A total of 2109 patients underwent 2792 abdominal flap tissue transfers for breast reconstruction in the 11 studies reviewed. A previous scar increased the risk of overall flap complications (RR 1.12; 95% CI, 0.95-1.32; fixed-effect model, I 2  = 13%) and donor-site complications (RR 1.35; 95% CI, 1.13-1.62; fixed-effect model, I 2  = 42%, p > 0.05). In particular, the risk of donor-site wound problem was significantly higher than that in the control group (RR 1.83; 95% CI, 1.35-2.46; fixed-effect model, I 2  = 19%, p > 0.05)., Conclusions: This study result showed that the previous scar increased the risk for all types of complications compared with the control group. In patients with a vertical midline scar, it requires careful preoperative planning with CT angiography and attentive follow-up. However, with careful preoperative planning and an appropriate strategy, it is possible to overcome the detrimental effect of previous scar., Level of Evidence: I., (Copyright © 2020 Elsevier Ltd.
