  • Abstract
  • Look Inside

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