The areas of the nasopharynx and its contents have been measured on the lateral cephalometric radiographs of 41 normal children who had been examined at yearly intervals for a minimum of 12 years between the ages of three and 19. The means and standard deviations of the areas of the nasopharynx, the soft tissues and the airway have been calculated for each year from three to 11 and for alternate years to age 19. The size and shape of the soft tissues of individual children are shown to vary from year to year, and the anterior convexity changes to a concave shape with maturity. The soft tissues appear to grow more rapidly from three to five than does the nasopharynx, with a consequent decrease in size of the airway at this period. Subsequently the soft tissue area remains relatively constant whilst the nasopharynx increases in size so that the airway progressively enlarges. There is a significant difference between the sexes in nasopharyngeal area from 13 onwards (p less than 0.005).
对41名正常儿童的头颅侧位X线片上的鼻咽部及其内容物区域进行了测量，这些儿童在3岁至19岁之间每年接受检查，最少检查了12年。计算了3岁至11岁每年以及19岁之前每隔一年的鼻咽部、软组织和气道区域的平均值及标准差。结果显示，个体儿童软组织的大小和形状每年都有所不同，随着成熟，前部凸度变为凹形。从3岁到5岁，软组织的生长速度似乎比鼻咽部更快，导致此期间气道尺寸减小。随后，软组织区域保持相对恒定，而鼻咽部尺寸增大，气道逐渐扩大。从13岁起，男女在鼻咽部面积上存在显著差异（p小于0.005）。
