Plagiocephaly without synostosis and sleep possition

We have noticed an increase in craneal deformities in healthy toddlers the last few years, probably due to sleeping position. A four years prospective study has been made in a consulting room of primary pediatric care. The frequence of plagiocephaly without sinostosis was 11.8% among newborn babies we have seen in this period, mean timing of initial diagnosis was 2.6 months and resolution occurred at 11.4 months. These findings suggest that this deformitie has a moderate frequency if its detection is carefully attempted and that positional changes should be recomended in babies who tend to rest their head always on one side.
