Lobotomy is a medical procedure that involves cutting or damaging certain parts of the brain to treat mental disorders. However, this controversial procedure has largely been abandoned due to its harmful effects on patients. For this reason, there are not many commonly used synonyms for lobotomy. The closest related terms may include psychosurgery, brain surgery, or neurosurgery. These terms may be used in a medical context to describe procedures relating to the brain. However, it is important to note that lobotomy remains an outdated and unethical procedure and is not recommended as a treatment for mental disorders.
