Pictured: X-ray of Australian teenager with 12-inch kitchen knife lodged in head after he SURVIVES attack

The 19-year-old was on a night out with a group of friends in Sydney, Australia, when he was attacked.

They had been to the harbourside Star City casino, but trouble broke out as they were heading home.

'A friend got involved in an argument with two guys behind me,' Alex said.

'I turned back to see if he was all right. Before I knew it, a fight broke out.

'One of the guys threw a punch in my face - or at least I thought it was a punch.'

In fact, Alex had been stabbed in the head with the kitchen knife.

Admitting he had never seen such a horrifying knife injury in which the victim had survived, the surgeon said Alex was 'unbelievably lucky'.

'Alex was stabbed in his right temple alongside the lateral canthus [the tissue where the upper and lower eyelids meet] of the right eye,' he said.

'Travelling parallel to the skull in the temporalis muscle [tissue on the side of the skull which controls jaw movement], the knife missed his eye, his skull, as well as the major arteries, veins and nerves, which are tightly packed in that region.'
