The Bertrand's method of selective peripheral denervation for spasmodic torticollis has already been established as being an effective and safe method. However, such effectiveness has not yet been established in Korea. The authors have performed several cases of selective denervation for the treatment of spasmodic torticollis and we hereby describe the details of the operative method to determine the effectiveness of the method. METHODS: Ten patients who had the selective denervation for the spasmodic torticollis from October 1997 to December 2003, were analyzed. There were 4 rotational and 6 combined types (3 rotational plus retrocollis, 3 rotational plus laterocollis). We performed preoperative electromyograms and neck muscle tonograms in all cases. The technique was used to involve denervation of the ipsilateral posterior paraspinal muscles. Denervation of the sternocleidomastoid muscle was performed on the contralateral side for rotational torticollis and on the ipsilateral side for laterocollis combined type. The surgery was followed by a rigorous physical therapy program. RESULTS: The surgical results were divided into 4 groups labeled excellent, good, fair, and poor. There were 5 excellent patients who showed no detectable abnormal movements, 4 good patients who showed slight residual deviations or slight residual abnormal movements, and 1 fair patient with appreciable residual abnormal movements. Postoperative pain was well tolerated. There was no significant surgical complications. CONCLUSION: The study confirms that selective peripheral denervation for the treatment of spasmodic torticollis is a very useful and safe surgical technique.
Key Words: Spasmodic torticollis; Selective peripheral denervation; Effectiveness
