Q. What's the difference between a lobotomy and a lobectomy?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Lobotomy and lobectomy are two distinctive brain surgeries, each serving different medical purposes. Let's explore the essence of these procedures to understand their significance in the field of neurosurgery.
What is a Lobotomy? A lobotomy, categorized as a psychosurgery, involves severing the connections between the frontal lobe and other brain areas to treat mental illnesses, most notably schizophrenia. Although widely performed in the 1940s, lobotomies have largely fallen out of favor due to severe side effects such as reduced motivation, impaired emotions, and personality changes. Presently, lobotomies are rarely utilized and considered as a last resort when all other treatment options have proven unsuccessful.
What is a Lobectomy? On the other hand, a lobectomy is a surgical procedure wherein a portion or the entire lobe (or section) of the brain is meticulously removed to address specific neurological conditions, including epilepsy or tumors. In some instances, lobectomy may also be considered as an alternative form of treatment for certain psychological disorders. Unlike lobotomies, lobectomies directly target the source of neurological issues, making them a more common and preferred option in contemporary medical practice. Many cases can now be treated using less invasive methods such as medications or electrical stimulation therapy (EST).
Key Differences: Intent and Approach The primary distinction between these two procedures lies in their intent. Lobotomy involves severing neural networks within the brain without removing any brain tissue. In contrast, lobectomy requires the selective removal of parts or an entire lobe from within the skull cavity. This procedure may involve either removing some neural networks while preserving others within intact structures or completely excising pieces, depending on the specific condition being treated.
