Abstract：Objective To investigate the efficacy of 2-month course of sleeping position correction in the treatment of positional plagiocephaly in infants aged < 8 months. Methods A total of 73 infants with positional plagiocephaly between January 2015 and June 2016 were divided into treatment group (n=46) and control group (n=27) according to parents' wishes. The treatment group received sleeping position correction, while the control group received sleep curve mattress. The oblique diameters A and B in the two groups were measured and the cranial vault asymmetry (CVA) was calculated before and after treatment. The severity of positional plagiocephaly based on CVA was compared between the two groups before and after treatment. The Gesell Developmental Scale was used to determine the developmental quotients (DQs) in the motor, adaptive, language, and social domains in the two groups before and after treatment. Results Before treatment, there were no significant differences in oblique diameters A and B, CVA, and DQs in the four specific domains between the two groups (P > 0.05). After 2 months of treatment, the treatment group had a significantly greater oblique diameter B and a significantly smaller CVA than the control group (P < 0.05); there were no significant differences in DQs in the four specific domains between the two groups (P > 0.05). After treatment, both groups had significant improvements in oblique diameters A and B, CVA, and DQs in the motor and adaptive domains (P < 0.01); moreover, the treatment group showed a significant improvement in the DQs in the social domain (P < 0.01). There was no significant difference in the severity of positional plagiocephaly between the two groups before and after treatment (P > 0.05). Conclusions For infants with positional plagiocephaly, sleeping position correction has better efficacy and is more convenient and economical than the sleep curve mattress, so it holds promise for clinical application.
