New research shows nearly half of all facial surgery in New Zealand is on young men who have been in fights while drinking.
Research published in the New Zealand Medical Journal by Christchurch surgeon Leslie Snape showed that 78% of alcohol-related fractures were the result of violence.
It found those aged between 16 - 30 years who had been drinking, were twice as likely to be hospitalised than those who were sober when they were injured.
Men made up 88% of those casualties.
The study looked at about 2500 patients over 11 years.
