A young man in India survived having a key lodged more than an inch into his skull, according to news reports. But how does someone survive an injury like this?
The man, a 19-year-old from the Ahmednagar district of Maharashtra, in India, was impaled with a motorcycle key during a brawl in his village on April 18, according to South West News Service (SWNS). At the hospital, doctors performed a brain scan, which showed that the key had pierced about 1.5 inches (3.8 centimeters) into the man's brain, said Dr. Ashish Bhandari, the administrator of Anand Rishi Hospital, where the patient was treated. The man underwent a 3.5-hour surgery to remove the key.
"Luckily, he didn't suffer internal bleeding, and there was no damage to his brain," Bhandari said. "Had there been severe internal bleeding, it could have cost him his life."
Dr. Justin Thomas, a neurosurgeon at Northwell Health's Southside Hospital in Bay Shore, New York who was not involved with the case, said it is possible to survive a penetrating injury to the brain like this. Survival "depends primarily on the location in the brain where the object is lodged" and whether there's damage to adjacent arteries or draining veins of the brain, Thomas said.

In particular, a person has a better chance of surviving a penetrating injury if it avoids an area of the brain called the superior sagittal sinus, which is one of the largest vein channels; it drains blood from the brain and runs in the midline (or center line) of the brain, Thomas told Live Science.
Damage to the superior sagittal sinus could result in bleeding in the brain or a blood clot that could lead to a stroke, he said.
People can survive a penetrating brain injury if surgery is "done in such a way that the object can be removed while minimizing damage to the surrounding brain structures" and minimizing the risk of bleeding after surgery, Thomas said.
The man was discharged from the hospital three days after his surgery and is recovering well, according SWNS.
