Usually the surgery is performed under local anaesthesia. If the surgery is more invasive, for example, umbilicoplasty is combined with abdominoplasty, general anaesthesia is used. Based on an individual case, different methods are used:
in the case of umbilical hernia, the hernia is corrected and excess skin is removed;
in the case of excess skin, the excess skin is removed and the remaining parts of the navel are fixed to the abdominal wall;
in the case of a concave but relatively wide navel, the navel is narrowed.
Sometimes the old navel is removed and a new one is formed to avoid scars. In the case of other deformities, an individual corrective method is selected. After the surgery the incision is stitched up and covered with a special plaster.
