Umbilicoplasty for large protruding umbilicus accompanying umbilical hernia: a simple and effective technique.

A large umbilical protrusion with redundant skin accompanying an umbilical hernia sometimes needs umbilicoplasty. Although several different techniques for making umbilical depression have been used, the results of the plastic surgery are sometimes unsatisfactory due to postoperative flattening or disappearance of the umbilical depression. To make a permanent umbilical depression that is cosmetically acceptable, we have modified the techniques. Umbilicoplasty was performed in 14 children whose ages ranged from 6 months-6 years and 3 months (median, 1 year and 10 months) and who had umbilical hernia with a large umbilical protrusion. After the fascial defect was closed, the diameter of the umbilicus was reduced to half that before surgery by removing fan-shaped skin flaps and approximating skin edges, and then inverting the umbilicus and fixing it caudally to the fascia and skin. There were no postoperative complications, and no flattening or disappearance of umbilical depression was observed during the follow-up of 10-19 months. The authors' technique of umbilicoplasty for a large protruding umbilicus accompanying umbilical hernia is a simple method that produces acceptable cosmetic results.
