This is Dr. Bonilla.
I understand your concerns. A normal liver size depends on height, sex and body mass. The normal size in the average population is 14 cm +/- 1.7 cm. However in tall men can be bigger. In you case the size is in the upper limit but still consider a normal variation. In patients on dilantin more than the size of the liver, it's important to check the function. Let me know if you have any other questions.
