Analysis of the correlation between deformational plagiocephaly and neurodevelopmental delay

Area of Science:

• Pediatric neurology
• Developmental pediatrics
• Craniofacial abnormalities

Background:

• Deformational plagiocephaly (DP) is a common condition characterized by cranial asymmetry due to external forces.
• A significant association between DP and developmental delay has been observed in previous studies.

Purpose of the Study:

• To investigate the relationship between the severity of deformational plagiocephaly (DP) and the degree of neurodevelopmental delay in affected infants.

Main Methods:

• Retrospective review of 155 patients diagnosed with DP between 2010 and 2016.
• Quantitative assessment of cranial deformation using the cranial index (CI) and cranial vault asymmetry index (CVAI).
• Evaluation of neurodevelopment using the Bayley Scales of Infant Development-II.

Main Results:

• The study population exhibited various cranial shapes, with brachycephaly being the most common (141 patients).
• A majority of patients (108) presented with severe cranial vault asymmetry (CVAI > 8.75).
• While statistically significant neurodevelopmental delays were noted, correlation analyses showed no definitive relationship between DP severity (CI, CVAI) and developmental indices (MDI, PDI).

Conclusions:

• Infants with DP demonstrate statistically significant neurodevelopmental delays, but accelerated development also occurs.
• The mental development index (MDI) is more susceptible to confounding factors than the psychomotor development index (PDI).
• This study did not establish a definitive link between the severity of DP and the extent of developmental delay.
