Neo-Omphaloplasty within a Vertical Scar: The Double Trapezium Flap Technique

Background: Various techniques for neo-omphaloplasty (or umbilicoplasty/umbiliconeoplasty) have been established in recent decades. However, when the omphaloplasty must be integrated into a vertical scar, most of these techniques are unsuitable. Method: We established a technique comprising two "cross-border" trapezium flaps that come together in a key-lock fashion to be applicable for umbilical reconstruction in vertical scars. Between 2020 and 2023, we performed the double trapezium flap technique in 11 patients requiring abdominal wall correction due to previous operations resulting in the loss of the original navel and a vertical midline scar. The follow-up period was 12 months. Results: We encountered two minor wound healing disorders not involving the omphaloplasty. One patient experienced a more severe wound healing complication involving the vertical scar and the lower flap of the neo-umbilicus. No cases of umbilical flattening or detachment of the anchorage stitches were detected. Patients ranked the aesthetic outcomes as "excellent" (n = 9) or "good" (n = 2). Physicians ranked the results as "excellent" (n = 7), "good" (n = 4), and "average" (n = 1). Conclusions: For the selected patients, this technique appears to be a good and reliable option to create a natural looking neo-umbilicus, creating sufficient umbilical depth with minimal scarring. While a study population of 11 patients is hardly enough to endorse a new technique, appropriate cases are comparatively rare and very specific.
