[Shape and aesthetic outcome evaluation of transposed umbilicus according to four surgical procedures]. / Évaluation de la forme et du résultat esthétique d'ombilics transposés selon quatre techniques chirurgicales.

ABSTRACT

INTRODUCTION: In abdominal plastic surgery, umbilicus is frequently transposed, generating scars and shapes variating with the techniques used. Various umbilical transposition techniques have been described, all of them attempt to reproduce the "ideal" umbilicus. This study aimed to define the shape and the aesthetic results obtained with four different surgical procedures, in order to choose an "ideal" umbilical transposition technique. PATIENTS AND METHODS: This retrospective study analyzed the characteristics of transposed umbilicus, in 50 patients who had undergone abdominal dermolipectomy for aesthetic reason, after a loss of weight or in breast reconstruction by Deep-Inferior-Epigastric-Perforator. Four surgical procedures were chosen, which differed by their counter-incision shape in the abdominal flap (Y, inverted Y, de-epidermized round with horizontal incision or U), and the deep points position of umbilical docking (along a horizontal or vertical axis). Shape and depth were evaluated by a panel of experts. The global assessment was based on a double evaluation, by the surgical jury and the patients themselves. RESULTS: The counter-incision type determined the umbilicus shape triangular for the Y (60%) or inverted-Y (41%), round for the U (52%) and vertical oval (67%) or round (32%) for the de-epidermized circle. The deep points position influenced the umbilicus axis. Regarding the appreciation, the de-epidermized circle had the best results for surgeons in a significant way, and for patients (respectively 72% and 100% satisfied), followed by the inverted-Y (57% and 92%) and Y techniques (55% and 89%) and at last the U (50 and 75%). CONCLUSION: Horizontal counter incision in a de-epidermized round, with two anchoring points on a vertical axis, generates vertical oval or round shaped umbilicus, considered attractive in the literature, and giving the highest aesthetic satisfaction for both surgeons and patients.
