In children with positional head deformity (posterior plagiocephaly), the occiput is flattened with corresponding facial asymmetry. The incidence of positional head deformity increased dramatically between 1992 and 1999, and now occurs in one of every 60 live births. One proposed cause of the increased incidence of positional head deformity is the initiative to place infants on their backs during sleep to prevent sudden infant death syndrome. With early detection and intervention, most positional head deformities can be treated conservatively with physical therapy or a head orthosis ("helmet").
在患有体位性头部畸形（后斜头畸形）的儿童中，枕骨扁平并伴有相应的面部不对称。1992年至1999年间，体位性头部畸形的发病率急剧上升，现在每60例活产中就有1例出现这种情况。体位性头部畸形发病率上升的一个可能原因是提倡婴儿睡眠时仰卧以预防婴儿猝死综合征。通过早期发现和干预，大多数体位性头部畸形可以通过物理治疗或头部矫形器（“头盔”）进行保守治疗。
