Abstract:
Purpose: To propose an objective method for evaluating the craniofacial asymmetry in congenital muscular torticollis patients, and to determine the correlation between the craniofacial asymmetry and clinical parameters such as age and the limitation of neck motion. Materials and Methods: Forty eight patients with congenital muscular torticollis, who underwent cephalometry for an evaluation, were enrolled in this study. The craniofacial curvature on the coronal plane, calvarial asymmetry, and mastoid process length were analyzed on the radiograph of the cephalometry. These radiographic measurements were analyzed to determine the correlation between the craniofacial asymmetry and clinical parameters. Results: The craniofacial axis was tilted to the affected side by 5.2degrees+/-2.8degrees. The skullbase axis was tilted to the affected side by 2.6degrees+/-2.6degrees, and the mandible axis was tilted to the affected side by 1.0degrees+/-2.3degrees. The difference in the mastoid process length from the skullbase was 7.0%+/-8.5%. The calvarial width from the vertical midline was 15.4%+/-11.6% larger in the affected side. In patients older than 5 years, the mandibular tilting angle (p=0.017) and the length of the mastoid process (p=0.007) were greater than those of the younger patients. Conclusion: We proposed a new objective method for quantifying the craniofacial asymmetry in congenital muscular torticollis patients. This method confirmed the patients to have an angular deformity and asymmetry in the craniofacial bone.
