The skull shapes of 615 consecutively born babies weighing over 2500 g were examined visually and by palpation. A characteristic deformity of the occiput was found which was strongly associated with breech presentation; it is suggested that this be termed hyptiocephaly. Severe forms of hyptiocephaly might partially explain the high incidence of occipital osteodiastasis in breech babies. A lesser occipital deformity was associated with occipito-posterior presentation. It was found that facial asymmetry declined with increasing parity. Statistical trends suggest that all of these abnormalities of skull shape are the effect, rather than the cause, of the abnormal fetal position.
对615例出生体重超过2500克的连续出生婴儿的颅骨形状进行了视觉检查和触诊。发现枕部有一特征性畸形，与臀位产密切相关；建议将其称为斜头畸形。严重形式的斜头畸形可能部分解释了臀位产婴儿枕骨骨分离的高发生率。较轻的枕部畸形与枕后位有关。发现面部不对称随着产次增加而减轻。统计趋势表明，所有这些颅骨形状异常都是异常胎位的结果而非原因。
