Pallidotomy
Pallidotomy
Pallidotomy (/pælɪˈdɒtəmi/) is a neurosurgical procedure wherein a part of the brain called the globus pallidus is lesioned. This procedure is primarily used to treat symptoms of Parkinson's disease, dystonia, and other neurological disorders.
Etymology
The term "Pallidotomy" is derived from the Latin pallidus meaning "pale" and the Greek -tomy meaning "cutting". It refers to the surgical cutting or ablation of the globus pallidus, a pale-appearing structure in the brain.
Procedure
During a pallidotomy, a small hole is made in the skull and an electrode is passed into the globus pallidus. The electrode is then heated to create a small lesion, which can help to reduce symptoms such as tremors, rigidity, and bradykinesia.
