Purpose: To evaluate the change in head shape in patients with a history of deformational plagiocephaly. Methods: The charts of all patients with the diagnosis of deformational plagiocephaly seen at the Loma Linda University Craniofacial Clinic from 1992-2002 were reviewed. Of these, all patients who had received a CT scan or MRI of the head prior to the age of 18 months were invited to participate in the study. A total of six children between the ages of 2-6 years were seen in our clinic for evaluation. Two children had received helmet therapy, four had not. The evaluation consisted of a questionnaire, cephalometric measurements of the head, independent parental and physician assessment of head shape deformity, and standard photographs. Results: Regardless of whether or not a helmet was used, most parents stated that their child's head shape had improved. Comparison of the patient’s current head shape tracing with their infant radiographic study also showed improvement of the head shape. However, most parents also noted that there was some persistent deformity. This was corroborated by physician assessment. Conclusion: Although deformational plagiocephaly appears to improve over time, many children continue to have a deformity that is noticeable to both parents and physicians.
