1. A surgical procedure in which part of the globus pallidus in the brain is destroyed or lesioned to treat movement disorders, particularly Parkinson's disease.
Usage: medical; neurosurgical; also called pallidectomy

Examples

• The neurosurgeon recommended pallidotomy as a treatment option for the patient's severe Parkinson's symptoms.
• Pallidotomy has been largely replaced by deep brain stimulation in modern neurological practice.
• The procedure involves creating a small lesion in the globus pallidus to reduce involuntary movements.
• Patients who underwent pallidotomy showed improvement in rigidity and tremor in some cases.
