Thalamotomy
Thalamotomy
Thalamotomy (pronounced: tha·la·mot·o·my) is a surgical procedure that involves the creation of lesions in the thalamus to treat movement disorders, such as Parkinson's disease and Essential tremor. The procedure is typically reserved for patients who have not responded to other treatments.
Etymology
The term "Thalamotomy" is derived from two Greek words: "thalamus," which refers to the part of the brain where the procedure is performed, and "otomy," which means "cutting into."
Procedure
During a Thalamotomy, a small hole is made in the skull, and a probe is inserted into the thalamus. The probe is then heated to create a lesion, which disrupts the abnormal brain activity causing the movement disorder. The procedure is usually performed while the patient is awake, so that the surgeon can monitor the patient's symptoms and adjust the location of the lesion as necessary.
Risks and Complications
As with any surgical procedure, Thalamotomy carries certain risks, including infection, bleeding, and damage to surrounding brain tissue. Some patients may also experience changes in sensation, speech difficulties, or problems with balance after the procedure.
