This cross-sectional study investigated developmental changes of pharyngeal airway structures. The materials were comprised of 120 lateral cephalometric radiographs and were divided into three stages according to the dental age. Results indicated that the upper pharyngeal depth increased with age, whereas, the lower pharyngeal depth was established early in life. The pharynx increases its capacity predominantly by vertical expansion. The developmental changes in pharyngeal structures were signficantly greater in males than in females.
这项横断面研究调查了咽气道结构的发育变化。材料包括120张头颅侧位X线片，并根据牙龄分为三个阶段。结果表明，上咽深度随年龄增加，而下咽深度在生命早期就已确定。咽部主要通过垂直扩张增加其容量。男性咽部结构的发育变化明显大于女性。
