A Comparison of Aesthetic Outcomes of Umbilicoplasty in Breast Reconstruction with Abdominal Flap: Inverted-U Versus Vertical Oval Incision.

[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.
