Dystonia treatment with selective denervation surgery

Selective peripheral denervation remains a surgical option for dystonia when conservative drugs can't help. It is used mainly for neck dystonia (cervical dystonia). During the operation, the neurosurgeon cuts the nerves that control the hyperactive muscles that cause the symptoms of dystonia. After the procedure, the tension in the muscles should stop. It is called "selective" denervation because the operation does not affect all muscles but only those affected by dystonia. Multiple studies show that a significant improvement persists over time in 30-60% of patients. Suppose dystonia of the neck affects many muscle groups. In that case, the operation is not performed since this will require cutting too many nerves, some of which you need to maintain movement. The surgery also is not indicated for patients with pronounced dystonic involuntary movements or head tremors. The procedure is performed under general anesthesia. The neurosurgeon makes an incision in the neck and then cuts some nerve endings connected to the affected muscles. After the operation, there may be some loss of sensitivity in the neck area. You might need physical therapy sessions to strengthen your neck after the operation.
