Association between dynamic asymmetry of the newborn's head and intrauterine factors.
A non-comparable, individual, observational and contemporary cross-sectional study in newborns was made to determine the dynamic lateralization in the head turning after release from the midline and its relationship with obstetric variables. From October to December of 2005, 320 newborns were admitted to the Adjacent Lodgings of the University Hospital of Santa Maria. From those, 89 were selected for assessment of the vestibular function since they have had previously fetal static control through ultrasound. Our results show that the right-sided head lateralization was significantly greater than the left-sided. The predominancy of the lateralization towards the right side also occurred in cephalic presentations and left-sided back, however these were not significant. Results corroborate with the existing literature and suggest an association between fetal static and vestibular function.
