A Brisbane veterinary clinic has performed a surgery to remove a part of a snake's jaw to help it eat again.

Veterinarian Emma Sciacca said the three-kilogram snake had a bone trauma to the right lower jaw that caused its teeth to heal abnormally.

The procedure was a first for the Brisbane Bird and Exotics Veterinary Services team when three-and-a-half-year-old python Tigerlilly was brought to them after refusing to eat for three months.
