Surgeons at the People's Hospital of Yuxi said they removed the blade Saturday after Li Fu, 37, came into the hospital Jan. 24 complaining of headaches, China's state-run Xinhua news agency reported Monday.
"A miracle of miracles: A knife pierced his skull and stayed in the nerve and vascular intensive area," neurosurgeon Luo Zhiwei said after the surgery.
Doctors said the blade apparently entered through Li's right lower jaw and lodged itself with the tip nearly touching his brain.
Li's brother said the man was stabbed during a robbery four years ago and police discovered a knife with no blade when they arrested the robber.
"The wound healed well, so he did not accept further examinations. We never thought the blade was left in his head," the brother said.
