The procedure as pioneered by Nobel laureate Egas Moniz in the 1930s consisted of drilling holes through the skull and severing or interfering with nerve fibers to the midbrain, particularly to the thalamus. In a later development, instruments were passed through the eye sockets to sever the connections. Lobotomies were performed on numerous patients between 1936 and 1956. In approximately one half there was at least temporary relief of symptoms. However, some patients exhibited worse behavior after the operation, and others whose tensions were relieved by the surgery degenerated to a vegetative state. Since the mid-1950s such psychosurgery has been largely abandoned in favor of less radical means of treatment, e.g., the administration of tranquilizers and other chemical substances. Most psychiatrists today do not view lobotomy as an acceptable form of treatment. lobotomy[lō′bäd·ə·mē] (medicine) An operative section of the fibers between the frontal lobes of the brain.

lobotomy [lo-bot´ah-me] a form of psychosurgery consisting of cutting of nerve fibers connecting a lobe of the brain with the thalamus. In most cases the affected parts are the prefrontal or frontal lobes, the areas of the brain involved with emotion; thus the operation is referred to as prefrontal or frontal lobotomy. Once fairly common as a method of controlling violent behavior, in recent decades its use has become rare because of the development of medications for treatment of severe mental illness, such as the antipsychotics that suppress violent symptoms of psychosis.lo·bot·o·my (lō-bot'ŏ-mē), 1.
