Abstract: Objective To understand the cranial shape of 6 to 30 month-old children with cerebral palsy (CP) in Shenyang,and to analyze its correlation with the mental development index (MDI) in the Bayley Infant Development Scale (BSID),in order to provide reference for promoting MDI in CP children. Methods Totally 663 CP children in four hospitals in Shenyang were selected as case group,and 587 non-CP children were selected as control group from February to September 2017. The STAR laser scanner performed a skull scan on the participants and the level of mental development was assessed with BSID. Results 1) The prevalence rate of cranial malformations was 40.7% in the 663 CP patients in the case group,29.3% and 11.4% for mild and moderately severe cases,respectively. The rate of cranial malformations was 31.7% in 587 non-CP children,20.9% and 10.8% for mild and moderately severe malformations. And the rate of cranial malformations in case group was significantly higher than that in control group (χ²=2.612, P<0.05),and so were for mild and moderately severe malformations (χ²=3.217,1.534, P<0.05). 2) Totally 43.7% of children in case group were screened as mental retardation (MDI≤69). And with the severity of head malformation increasing,MDI gradually decreased (χ²=0.025,P<0.05). Conclusions Cranial malformations are associated with mental development and may be a risk indicator of mental retardation,especially in children with CP. Medical staff and parents should pay attention to the relationship between skull shape and intelligence development,attach importance to the inspection of the head shape of infants,in order to reduce the incidence of skull deformity.
