Spasmodic torticollis (cervical dystonia) can be a disabling condition resulting in neck pain and deformity. Patients with refractory torticollis, despite physical therapy, medications, and injections of neuromuscular blockade, may be surgical candidates. Selective denervation is a well-known but relatively rarely performed procedure that can be considered for patients with rotational torticollis, laterocollis, or retrocollis. Denervation of the C2–6 dorsal rami and spinal accessory nerve can be performed with myotomy of the sternocleidomastoid and levator scapulae, and myectomy of the splenius capitis or semispinalis capitis muscles. Results often improve pain and head position but do not cure the underlying dystonia. Risks are relatively rare.
