Complete tight fibrous band release and resection in congenital muscular torticollis

Abstract

Congenital muscular torticollis (CMT) is caused by shortening of the sternocleidomastoid (SCM) muscle, which may lead to neck movement limitation and craniofacial deformity. The authors retrospectively reviewed clinical experiences of CMT at their hospital from February 2007 to June 2008. During the study period, 20 CMT patients underwent complete tight fibrous band release and resection. Mean patient age was 47.6 months at operation. Eighteen of the 20 patients started a programme of physical therapy preoperatively. All patients received well-controlled postoperative physical therapy and wore a soft neck collar to correct head position for at least 3 months. At 3 months postoperatively, passive ranges of neck motion were determined, and compared with those of uninvolved sides. Eighteen patients showed a full range of motion of neck rotation and lateral flexion, but one patient showed a 10 degrees limitation in lateral flexion, and another showed 10 degrees limitations of neck rotation and lateral flexion. The authors recommended that the described operative technique involving complete fibrous band release and resection, combined with intensive postoperative physical therapy and application of a soft neck collar, provides good functional and cosmetic results.
