Abstract
BACKGROUND: We investigated the utility of pallidotomy for cervical dystonia following failed selective peripheral denervation.
CASE DESCRIPTION: A 36-year-old man presented with cervical dystonia with limited range of motion of the left shoulder, particularly in abduction. His Tsui score was 8. Due to the ineffectiveness of botulinum toxin injection, he underwent selective peripheral denervation with an unsatisfactory outcome, with a postoperative Tsui score of 6. Simultaneous bilateral pallidotomy was performed with local anesthesia at one year after the initial surgery. The day after the pallidotomy, all dystonic symptoms were markedly improved except for the limited range of shoulder abduction. The Tsui score was recorded as 1 at one week after the pallidotomy. Transient aggressive behavior was the only postoperative complication in the present case. During clinical follow-up period of one year, no recurrence of the symptoms was observed.
CONCLUSIONS: Pallidotomy represents a feasible and efficacious treatment for cervical dystonia refractory to SPD without hardware related complications.
