A lobotomy piercing is not a medical term or procedure. A lobotomy is a type of brain surgery that involves severing the connection between the frontal lobe and different parts of the brain. It was developed in the 1930s as a treatment for mental health conditions such as schizophrenia. The procedure was later modified by American neurologists Walter J. Freeman II and James W. Watts, who developed the Freeman-Watts standard lobotomy. In 1945, Freeman streamlined the procedure, replacing it with transorbital lobotomy, in which a pick-like instrument was forced through the back of the eye sockets to pierce the thin bone that separates the eye sockets from the frontal lobes. However, lobotomies are now considered obsolete and are rarely performed.
