This week's West Aussie Great is Professor Marcus Atlas, a world-renowned ear, hearing and skull base surgeon scientist based in Perth.

Professor Atlas has a worldwide reputation in ear and hearing surgery and disorders, and is one of few surgeons whose outcomes are published in international journals.

Caller Margaret, who used to be deaf, told Parker that Atlas had changed her life.

"He's not only a West Australian Great, he's actually my hero," she said.

"I was virtually deaf and went to see him, and I can now hear everything. I can hear the birds singing, I can hear my grandson, and he's amazing."
