Svennilson's Publication on Pallidotomy for Parkinsonism in 1960: A Most Influential Paper in the Field.

The study design was prospective and patients were followed up for at least 1 year after surgery with the earliest patients of the series having follow-up for 5 years. Presently, we already see a re-emergence of lesioning surgery in the form of MR-guided focal ultrasound and other techniques.35 Certainly, there is a need for functional neurosurgeons worldwide to preserve knowledge and skills about therapeutic lesions in movement disorders surgery. The operation had little effect on dysarthria, but transient "dysphasia" was noted in 24% of patients with wide ventricles, and in 7.5% of those with normal ventricles when surgery was performed on the dominant hemisphere.
