A clinical analysis of 101 infants with plagiocephaly / 中国当代儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the possible causes of plagiocephaly in infants and the therapeutic effect of postural correction training on plagiocephaly.</p><p><b>METHODS</b>A total of 101 infants who were diagnosed with plagiocephaly were enrolled. According to the age at diagnosis, these infants were divided into 1-4 month group (31 infants), 5-8 month group (40 infants), and 9-12 month group (30 infants). The possible causes of plagiocephaly were analyzed in three groups. The cranial vault asymmetry index (CVAI) before and after postural correction training was compared in three groups.</p><p><b>RESULTS</b>Of the 101 infants, 89 (88.1%) had a sleeping posture in the supine position, and there was no significant difference in the percentage of infants with such posture between the three groups. Compared with the 5-8 month group and the 9-12 month group, the 1-4 month group had significantly higher rate of preterm birth, incidence rate of adverse perinatal factors, and incidence rate of congenital muscular torticollis. The three groups showed a significant decrease in CVAI 3 months after postural correction training (P<0.001). Compared with the 5-8 month group and the 9-12 month group, the 1-4 month group had a significantly greater change in CVAI after postural correction training (P<0.001).</p><p><b>CONCLUSIONS</b>The sleeping posture in the supine position may be associated with the development of plagiocephaly. Adverse perinatal factors, preterm birth, and congenital muscular torticollis as possible causes of plagiocephaly are commonly seen in early infancy. Postural correction training has a significant effect in improving plagiocephaly, especially in early infancy.</p>
