在30例（男19、女11）新生儿尸体上，解剖观察了食管的形态和位置；测量了食管各段长度，食管全长为89．90±6．11mm，与身长之比为1：5．5，与臀顶长之比为1：3．8；测得从上牙槽正中至食管起始处、左主支气管压迹处、穿隔处及贲门中点的距离分别为66．02±5．81mm、108．02±7．42mm、144．93±9．08mm、155．91±9．65mm；鼻孔至以上四处的距离分别为80．42±5．81mm、122．33±6．41mm、159．33±9．01mm、170．31±9．54mm；同时测量了以上四处及颈胸交界处、食管最宽处的内横径、外横径和管壁厚。
The morphology and location of the esophagus were observed anatomically on the corpses of 30 newborns (19 males and 11 females). The length of the esophagus was measured. The total length of the esophagus was 89.90 ± 6.11 mm, the ratio of body length to body length was 1: 5.5, and the ratio of the length of the top of the hip to 1: 3.8. The distance from the middle of the upper alveolar to the beginning of the esophagus, the left main bronchial lesion, the middle of the perforation and the cardia was 66 respectively. 02 ± 5.81mm, 108.02 ± 7.42mm, 144.93 ± 9.08mm, 155.91 ± 9.65mm respectively. The distances from the nostril to the above four were 80.42 ± 5.81mm and 122.33 ± 6.41mm, 159.33 ± 9.01mm and 170.31 ± 9.54mm respectively. Meanwhile, the inner diameter, outer diameter and wall thickness were measured at the four locations and at the junction of the neck and the chest and the widest part of the esophagus.
