AbstractEighteen patients with congenital muscular torticollis, aged 6-22 (average 11) years, underwent surgical releases of the contractive bands. There were 8 boys and 10 girls. Preoperative open mouth radiograph of the odontoid process in 16 patients showed asymmetry of articular facets of the axis and tilt of the odontoid process to the side of the torticollis. Sixteen patients received bipolar releases, the others received distal releases. After the operation, a neck collar was applied and an exercise program was started. At an average follow-up of 5 years and 7 months, there were excellent or good results in 10 patients. All of the patients except 2 showed improvement of the facial asymmetry and all except 1 had a satisfactory range of motion of the neck. One patient underwent a second operation due to recurrence. The follow-up radiographs showed improvement of the tilt of the odontoid process, but the asymmetry of the articular facets of the axis persisted. We suggest that bipolar release is the treatment of choice for congenital muscular torticollis in patients of more than 6 years of age. To determine the influence of a bipolar release on the functions of the cervical spine, longer follow-up intervals are needed.
