Better than Pre-Op
In fairness, I have never had an umbilical hernia
repaired (u need a different website for that), but I have fixed hundreds.
The cosmetic results depend on the size of the hernia, the size of the patient, and the method of repair. If you see a hernia surgeon, they can draw what your scar will look like and describe the cosmetic changes. Either way, it will look better than before surgery :-).
