    Patients with laterocollis or rotatory type torticollis tend to show abnormal contraction of the levator scapulae muscle and the scalene muscles. These muscles are innervated from the anterior branches of the cervical spinal nerves. Because of this, the traditional Bertrand operation dealing with posterior branches does not adequately affect the symptoms of laterocollis. The authors report selective denervation of the levator scapulae muscle in three patients and discuss its rationale. All the three patients underwent denervation of both the C1 - C6 posterior spinal rami and the branches from the C3 and C4 anterior rami to the levator scapulae muscle. We added myotomy of the scalene muscle in one patient, and denervation of the omohyoid muscle which is innervated from the ansa cervicalis and the descending branch of the hypoglossal nerve. The pre/post-operative Tsui scores were 12/4, 15/1, and 14/3 respectively. There were no complications. We conclude that selective peripheral denervation of the levator scapulae muscle is safe and effective in the treatment of laterocollic type torticollis.
