Introduction. The recommendation for supine sleeping position to decrease the risk of sudden infant death has increased the frequency of plagiocephaly without craniostenosis (PWC). This should be differentiated from true craneostenosis (CS). Objective. To identify and quantify causes of PWC, indicate appropriate treatment and observe its outcome. Population, material and methods. Design: prospective, descriptive, observational and analytic study with a comparison group. Inclusion criteria: infants under 12 months of age consulting from March 2000 to February 2001 because of cranial deformation. Exclusion criterion: loss of follow up. PWC patients where compared with a normocephalic control group. Results. 41 patients: 34 (83%) were PWC (25 right occipital) and 7 (17%) CS. There were no statistically significant differences in the age of detection and consultation, follow up time or sex. When compared with normocephalic children (n= 98), in the PWC group there were significantly more boys, torticollis, neurological problems, low birth weight, macrocrania, and supine position. There were no significant differences in gestational or delivery problems, gestational age or Apgar scores. Outcome in PWC was partially or totally favorable in 30 patients (88%). Conclusion. PWC is much more frequent than CS. Risk factors for PWC are: supine sleeping position, torticollis and neurological problems. Complex complementary exams are not necessary. With adequate recommendations outcome is very good.
