He's very lucky to be alive, it would be interesting to see an xray.

Sanjay Bahe , a 21-year-old laborer, was working at a construction site when he fell into a well and the rod directly pierced his head. The young man, originally from Balaghat, in central India, was immediately taken to the BJ hospital, near Gondia, in the state of Maharashtra.
The bar was removed by a team of neurosurgeons after an operation that lasted ninety minutes at the Neuron Hospital. Although the surgery was complicated by the critical state of low blood pressure with which Bahe was admitted, after an hour and a half, doctors were able to remove the bar safely and with almost no bleeding or injury to the surrounding area, the doctor reported.
According to Dr. Pramod Giri, the neurosurgeon who led the operation, the main channels that carry blood to Bahe's brain were saved by just millimeters.
"Applying anesthesia to the patient in such cases is difficult," the doctor said. "We did the right thing by placing the intubation to maintain vital channels in the brain during the operation." "I performed the surgery with all caution so as not to cause damage to the surrounding structures," Giri said.
The doctor added: "A complication that can occur in these cases is causing meningitis in the patient."
However, he said that Sanjay Bahe was recovering successfully and that they were monitoring to prevent meningitis for the time being.
