Abstract
OBJECTIVES: Congenital muscular torticollis is a common and controversial condition in infancy. We studied prospectively a group of infants with clearly defined sternomastoid tumor treated with a well-defined protocol. STUDY DESIGN: A total of 510 cases of sternomastoid tumor in infants over a 10-year period were studied prospectively with a mean follow-up of 3.5 years and a range from 1. 5 years to 13 years. The clinical presentations, associated abnormalities, treatments, and outcomes of the overall group and subgroups were evaluated to determine the most important prognostic factors. RESULTS: The mean age of presentation was day 24, with most (92.7%) presenting before the age of 3 months. There was a high correlation with breech presentation and assisted delivery. Clinical subgroups according to the deficit in passive rotation of the neck correlated with the incidence of hip dysplasia (up to 11.6%), mode of delivery, time of presentation, degree of craniofacial asymmetry, head tilt, and the size and extent of the pseudotumor (P <.05). With an early and prolonged manual stretching program, 90.7% had excellent and good overall results. The 6.7% of patients in the poor outcome group requiring surgical treatment all belonged to the more severe rotation limitation groups. CONCLUSIONS: Subgrouping patients with sternomastoid tumor according to the passive limitation of rotation of the neck has prognostic significance, with good overall results of conservative treatment with manual stretching.
