Plagiocephaly--new classification and clinical study of a series of 100 patients.

The term of 'plagiocephaly' coined by Virchow in 1851, that literally means 'cranial asymmetry' has been applied to dysmorhic skulls that look similar but which sometimes have a different etiology. The authors report a new clinical classification of plagiocephaly in order to simplify the categorization of this disease. A series of 100 patients with plagiocephaly were observed and treated. A clinical investigation of these cases, some considerations about the techniques used, the analysis of the results and a long-term follow-up complete the study reported.
