Cervical dystonia is the most common form of local dystonia encountered in a movement disorders clinic. Rotatocollis is involuntary contraction of sternocleidomastoid and contralateral splenius muscles resulting in twisting of the head clockwise or counterclockwise on the axial plane. We injected phenol solution into the affeced muscle or nerve branch in two patients with rotatocollis. There was significant improvement in neck movement and position. Phenol block may offer an easy and inexpensive alternatives for patients with cervical dystonia. (J Korean Acad Rehab Med 2005; 29: 438-440)
