3D-printed plastic used to patch up this man's skull

In November 2016,Etienne Coon-Come Masiringi suffered severe head trauma and brain swelling, forcing doctors to remove part of his skull to relieve the pressure.

And when he finally woke up in a hospital bed,he couldn'trecall what brought him there.

"I just remember being very confused, and a little bit angry, because not only was a piece of my skull missing but alsoI had dreadlocksbefore,and the dreadlocks were gone," he told CBC Radio'sOttawa Morning earlier this week.

Accounts vary aboutwhat happened the night he was injured. Doctors told Coon-ComeMasiringihe fell from a balcony, but later on he was told he'dbeenassaulted.

Coon-Come Masiringi may never know what actually happened that night.

Dark moments

After the piece of skull was removed,he had to protect his exposed brain by wearing a helmet while standing, even after he left the hospital.

He felt self-conscious about it, and foundit difficult to relax in public.

"Having that helmet,it was just a constant reminder of what happened that night," he said. "There were some dark momentswhere I was depressed and just not in a good mood."

It continued for 10 months,until doctors were able to replace the missing piece of his skull with a 3D-printed piece of plastic.

He said it's helped he put the incidentbehind him.

'Feels a little bit different'

His skin grew back on top of the 3D printed piece, and with it his hair.

"Sure it feels a little bit different than the rest of your skull, but other than that it looks exactly the way it did before the injury," he said.

"Physically I feel just top shape, and I'm looking forward to the future."

Coon-ComeMasiringiwill return to Carleton University next week, where he is starting his third year studingsocial work. He also is volunteering at the Ottawa Hospital, taking inspiration from the volunteers whohelped him through his recovery.

But what he looks forward to most is the return of the dreadlocks that originally took him three years to grow. He'sbeen re-growing his hair for about eight months.

"I'm just in the beginning stages but I will get to my destination."
